It feels like a long time since Altair first adventured through the Holy Land. Now Assassin’s Creed, by Ubisoft, became one of the highest selling video game franchises of all time. It is even bigger if you consider the novels, comic books, animations, and well… that movie-thing. It is also one my top 3 favorite game series, so no wonder it would pop up on one of my articles eventually.

Besides the nice action and beautiful historical settings of Assassin’s Creed games, my favorite moments are when I suddenly stumble upon one of my real-life heroes. I enjoy talking to their in-game reconstructions and to see how they match both my expectations and the historical accounts of their real-world counterparts. Most of these people are, of course, scientists, even though some lived in a time where the word “scientist” was yet to be coined.

So, my goal here will be to show how these people are portrayed in Assassin’s Creed and how this matches reality. I will also explain their major achievements and their importance to science. But with so many games in the franchise, it would be a monumental task to write a single article with every scientist; thus, I decided to present this in parts. The first one, as you might have surmised from the title, will be about James Cook and Charles Darwin.

At first sight, this might seem a strange pairing, but it has its reasons. I’ve chosen to start with them because this year marks some anniversaries – and us humans just can’t help but be attracted to round numbers and meaningful dates. The year of 2019 marks 250 years from Cook’s historical first visit to New Zealand and 240 years from his death. It is also Darwin’s 210th would-be-birthday and the 160th birthday of the most groundbreaking book ever written: On the Origin of Species.


James Cook was born on 7 November 1728 in Marton, in North-East England. He attended local school, apprenticed as a shop boy, and in his late teens became a merchant navy apprentice. During that time, he learned navigation skills and a healthy dose of algebra, geometry, trigonometry, and astronomy. In 1755, he joined the Royal Navy, just when Britain was preparing for the Seven Years’ War.

Cook served aboard several ships; most remarkably, he was part of the HMS Pembroke crew when the British captured the Fortress of Louisbourg from the French in 1758, during the Seven Years’ War. Due to his talent as a cartographer, he was put to good use during that time, mapping several parts of Canada in the late 1750’s and early 1760’s (then aboard the HMS Grenville). This is the part of his life seen in Assassin’s Creed, but he is most famous for what came afterwards; so let us take a look at that before turning to the game.

In 1768, the Admiralty made Cook lieutenant and put him in command of the HMS Endeavour on a scientific voyage to the Pacific Ocean. His main goal was to observe the transit of Venus[1] in Tahiti in 1769, which would help to determine the distance of the Earth to the Sun (the solar parallax). After that was out of the way, Cook opened an envelope with further orders: to navigate the South Pacific in search of the hypothetical continent Terra Australis and to find New Zealand’s eastern shores. He set off to the south and then westwards, reaching New Zealand and precisely mapping its entire coast. He also took the opportunity to record the transit of Mercury. Cook also needed to document the flora and fauna and establish a relationship with native people; in the long term, the goal was to acquire their consent to take the land for His Majesty. That was the beginning of the British history of New Zealand.

BOX 1. The discovery and naming of New Zealand

Despite what might be assumed, Cook did not discover New Zealand. Polynesian settlers arrived there between 1200 and 1300 CE and became known as the Māori. They called their new home Aotearoa.

The first non-Polynesian person to arrive in New Zealand was Dutch explorer Abel J. Tasman, who first sighted the shores of South Island in December 1642. Tasman’s crew would have landed there, but were driven off by the Māori. They assumed that land could be the western shore of the imaginary continent Terra Australis. In any event, Tasman named the “new” land Staten Landt, which is a straightforward horrible choice. Dutch cartographers recognized this and renamed the place Nova Zeelandia in 1645, after the province Zeeland in the Netherlands. This name stuck, even under later British control.

Even though he did not stay long, Tasman literally put New Zealand on the map and right under the radar of European colonial efforts. His name lives on today in the Tasman Sea (separating Australia and New Zealand), in Tasmania (Australia’s southern island), and in the Abel Tasman National Park (in northwestern South Island, New Zealand).

Once back in England, Cook was promoted to commander and sent on a second voyage in search of Terra Australis, which everyone now knew was not New Zealand. Cook took the HMS Resolution, with the HMS Adventure serving as its companion ship, and navigated the southern oceans. He almost reached Antarctica, but his “failure” to find land put an end to the Terra Australis myth.

Back in England once again, he was made captain and soon became involved in a third voyage, commanding the HMS Resolution once again (the companion ship this time was the HMS Discovery). His goal was to find a northern passage, through the Arctic, from the Pacific to the Atlantic. He couldn’t do it, of course, and became frustrated with the voyage. During a prolonged stay in Hawaii to fix the ship, tensions began to rise with the locals. Cook tried to kidnap the Hawaiian king to put an end to it; the Hawaiians naturally didn’t like that and Cook was killed.

Captain Cook was responsible for mapping large parts of the world, as well as for several astronomical observations and for collecting dozens of ethnographic artifacts. He might not convey the impression of the typical scientist, but can and should be counted as one.

He was not the only scientifically-inclined person on his expeditions, though. During his voyages, Cook counted with botanists Joseph Banks and Daniel C. Solander, astronomers Charles Green, William Wales and William Bayly, and naturalists Herman Spöring, Johann R. Forster, Georg A. Forster and David Nelson. There were also artists to illustrate the new lands, their people, flora and fauna.

Cook features in Assassin’s Creed: Rogue (henceforth ACR), released in 2014 for the Xbox 360 and PlayStation 3 (2015 for Microsoft Windows) and remastered for the Xbox One and PlayStation 4 in 2018. This game is different from the others in the series in that you play as a Templar instead of an Assassin. The game follows Shay Cormac in his convoluted journey from Assassin apprentice to senior Templar.

Cormac first encounters Cook towards the middle of the game’s story. By that time (June 1758) Cook was master of the HMS Pembroke. Even though he appears several times, his presence is not as well-marked as one would hope. Cormac and his crew go after him due to his “mathematical mind” and expertise in deciphering secret codes. They comment that Cook’s “seamanship is second-to-none” and that he had a self-policy of strict honesty. Cormac and his colleague Gist discuss how Cook would be a good addition to the Templars, but in the end decide that his total lack of guile would be bad for the Order: the man would not be able to keep the secret.

The presentation of Cook’s character and personality is in line with contemporary sources and his many later biographies, which paint him as intelligent, honest and driven. However, he faced many trials during his voyages and sometimes dealt with them using more brutality (towards his crew or the native people of the Pacific) than we can now accept. Furthermore, he seemed to have had a drastic change of personality on his third voyage. In any event, the depiction of young James Cook in ACR is very compelling.

The first mission in ACR involving Cook is very straightforward: to beat the French. Cormac takes the helm of the HMS Pembroke to aid Cook in turning the tide of the battle and finally, capturing the Fortress of Louisbourg. This aligns rather nicely with the historical record.

Cormac meets Cook again in Percé, in 1759, and asks him to decipher some encrypted maps. Cook also helps in tracking down a French-Canadian Assassin, after which he asks Cormac whether he belonged to a larger organization. After getting a reply in the lines of “we couldn’t say even if we were”, Cook then assumes Cormac and his crew were under direct orders of the King. The Templars seem satisfied with this and do not correct Cook. Instead, they say their group will contact him about sponsoring future voyages.

The last bit is a clear reference to Cook’s three exploration voyages to the Pacific. What interest the Templars might have there remains unknown for the moment, but it could definitely involve Terra Australis. In any event, real-life Cook indeed got the attention of the Admiralty and the Royal Society during his years in Canada, especially because of his incredible work mapping Newfoundland; indeed, this latter led to his appointment as commander of the first Pacific voyage.


Darwin (1809–1882) needs no introduction – but here’s one anyway. He is THE most important figure in Biology and of the most important scientists of all time. He is most famous for his book On the Origin of Species (henceforth Origin), first published in 1859, but his contributions to the natural sciences extend beyond that. As late American paleontologist Stephen J. Gould argued, Darwin’s ideas rank with Copernicus in the way they revolutionized not only science but also the very way our silly species sees itself.

There is simply way too much to write about Darwin: his early life, his voyage, his books, his garden experiments, his immense legacy, etc. There are dozens of books written about him and, if I start writing all the things I find interesting here, I might just end up with a whole book. Since I do not want that, I will focus here on very small parts of his life that are related to what happened in the game.

Darwin features in Assassin’s Creed: Syndicate (henceforth ACS), released in 2015 for the Xbox One, PlayStation 4 and Microsoft Windows. The game takes place in London, starting in 1868, and revolves around the brother and sister pair of Assassins, Jacob and Evie Frye.

In the game, you first meet Darwin investigating a factory that produced an opium-based drug called “Soothing Syrup”. It was made by the Templars, of course, and Jacob decided to help Darwin in his investigation. They find out that Richard Owen (see Box 2), who was responsible for an article defaming Darwin, knew something about the syrup. Jacob interrogates Owen and discovers the name of the doctor who was behind the new drug, confronting and killing him in an asylum.

BOX 2. Sir Richard Owen

Owen is clearly linked with the bad guys in ACS. He was a controversial figure indeed, hated by his adversaries, but maybe not quite the “video game villain” kind. Sir Richard Owen (1804–1892) was a brilliant naturalist and authored outstanding works in animal anatomy and paleontology. In fact, he is the one who coined one of the most important words in our vocabulary, “dinosaur”. He is also responsible for the magnificent Natural History Museum in London, built as a cathedral of Nature.

However, Owen opposed Darwin’s idea of evolution by natural (and sexual) selection. Owen was well aware of the anatomical features that established lines of descent and relatedness among animals. Still, his belief in human uniqueness, immersed in what he saw as “natural order” arranged by a creative power, escalated his quarrel with Darwin and his followers, mainly Thomas H. Huxley and Joseph D. Hooker. He could not agree with humans being “just” a weirdly naked species of ape.

In ACS, Darwin even says to Owen: “Mr. Owen, you are truly the most insufferable fellow I have ever had the misfortune to count among my acquaintances!” In real life, after Owen’s involvement in an event that undermined one of his colleagues, Darwin wrote in a letter: “I used to be ashamed of hating him so much, but now I will carefully cherish my hatred & contempt to the last days of my life.”

Back to the real world, first I should point out that Darwin was somewhat of a hermit. He lived in the countryside near London since 1842 and his home was known as Down House. Darwin reportedly did not enjoy going into town that much, so you would be hard pressed to find him in London as the Frye twins did. But that is totally excusable, as a game set in Victorian London must include Darwin somehow. Also, by that time Darwin already had his share of adventures during the voyage of H.M.S. Beagle around the world, so you would be even more unlikely to find him poking around criminal activities in London. Thus, the whole “Soothing Syrup” quests would be very unlikely, especially because they involve more medicine and chemistry than actual biology.

Later on in ACS, the Frye twins meet Darwin again, who says that his critics were threatening him and his colleagues with violence. He was waiting for a certain German colleague of his, identified in the game simply as Dr. Schwartz, who was bringing an important fossil to London. Darwin asks the Fryes to protect Schwartz, but they discover that the German scientist was intercepted and killed by Templars. Even so, they manage to recover the fossil and deliver it to Darwin.

This mission is simply perfect for the setting, even though it is slightly historically inaccurate. The mission is called “The Berlin Specimen”, which is a name that can only refer to one thing: the fossil specimen of Archaeopteryx lithographica from the Natural History Museum (Museum für Naturkunde) of Berlin. This species is one of the most important in the world from a historical perspective: its first fossil was discovered in southeastern Germany just two years after Origin was published and was a major evidence in favor of Darwin’s work, showing that the origin of modern birds lays within the group of theropod dinosaurs.

The Berlin specimen is the most famous (and most complete) of all the fossils of Archaeopteryx lithographica; we typically see a replica of it in exhibition in museums worldwide. However, it was only discovered somewhere in 1874–1876, some years after the setting of ACS, but still reasonably close. Curiously, a man named Schwartz, from Nuremberg, tried to buy the actual fossil before it was bought by the Berlin museum (funded by Werner von Siemens, founder of Siemens AG).

There is in fact a “London specimen” of Archaeopteryx, discovered in 1861 and bought by none other than Richard Owen for the Natural History Museum in January 1863. Perhaps this fossil would have been more appropriate for ACS; especially given that Owen is already in the game.

Back to ACS, Darwin first asks the Fryes to investigate a plant that can make people delirious and then to secure him a copy of that day’s newspaper, which had a rebuttal to Owen’s defamation mentioned above. The Fryes then discover a Templar plot to spread newspaper articles with anti-Darwin propaganda, epitomized as a caricature.

This caricature, entitled “A Venerable Orang-outang” is seen in ACS and it was a real thing, published by The Hornet magazine in 1871, after Darwin published his book The Descent of Man (extracted from Wikimedia Commons).

In fact, Darwin was constantly under the radar of the Templars in ACS, who tried to buy him (and his research) out. Darwin answered that “[s]cientific knowledge cannot be bought, it belongs to everyone.” The Fryes, of course, would come to his aid. They discover who was behind the caricature (spread through London as posters) and sabotage the printer shop.

Darwin’s ideas of evolution[2] by natural and sexual selection and their implications for our own species were the cause of many heated debates during his lifetime. In fact, to this day many people are still in denial regarding his ideas (especially in religious countries like the US and Brazil), despite the massive amount of evidence in his favor. Darwin knew this would happen and that is basically why he took so long to publish his main book: he needed to amass as much supporting evidence as he possibly could. In ACS, Darwin says to Evie that “I am used to people challenging my ideas”.

The last mission involving Darwin in ACS is called “A Struggle for Existence” and alludes to the full title of his main book: “On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life”. But the mission is not as poetic as it sounds; rather it is very literal. It begins with Florence Nightingale telling the Fryes that Darwin had been arrested and that she feared that “Mr. Darwin is no longer the fit, young man who once traveled the world.” The Fryes then rescue him from a Templar base and Florence suggests that Darwin retired with his family to the Isle of Wight to recuperate in peace. Darwin, though, argues that “[t]he acquisition of knowledge is in itself sufficiently recuperative.” Real-world Darwin actually spent a holiday with his family on the Isle of Wight during 1868; the latter of the photos shown above was taken there.


As I said in the beginning, Cook and Darwin (and Owen, I suppose) are hopefully just the first on a series I intend to write exploring all the real-world scientists that feature in the many Assassin’s Creed games. (I’ll definitely include Florence Nightingale at some point, in case you were wondering.) Also, since several games take place before the establishment of modern science, you’ll also see some philosophers and historians around here. Until next time!

Dr. Rodrigo Salvador is a biologist who studies mollusks or, to put it shortly, a malacologist. He loves reading about the scientists of old and can’t help but share this sometimes. He is hyped by Assassin’s Creed games ever since the very first images of Altair came out. His favorite entry in the series is Origins, because… Egypt, but his favorite Assassins are still Ezio and Evie.

[1] Herdendorf (1986) argued that the Transit of Venus, first in 1761 and then in 1769, was the first international collaborative effort in science, including dozens of observers in tens of stations spread worldwide. He considered it as the establishment of the modern scientific international community.

[2] Actually, while Darwin was working on his book another British naturalist, Alfred Russel Wallace (1823–1913), independently conceived the idea of evolution through natural selection. His work on the subject was jointly presented with Darwin’s in 1858 to the Linnean Society of London.

Fantastic beasts and how to diversify them

Despite their secrecy, fantastic beasts are oftentimes noticed by muggles. Their diversity, however, was never subject of any study in order to understand what could have driven it. At least two groups of creatures show that both historical and environmental aspects played role on these organisms’ lineages’ splitting events, leading to their current distribution on the globe. Additionally, nonspecialist readers that enjoy Harry Potter culture might become interested in the topic and, as such, fictional content can represent an innovative tool of science outreach to introduce evolutionary biology and biogeography concepts to the general public.


Not even special clauses (Scamander, 2001) prevented muggles of noticing fantastic beasts among them. They are part of our days probably since before we started creating tales about them (d’Huy, 2013). Present in all continents, except Antarctica, magical creatures occupy an unequal variety of niches, from herbivorous forms to fire-eating beasts (Scamander, 2001). All the main differences described for such creatures may reflect not just local traditions or modifications from oral stories, but actual lineage branching events (e.g., Hamilton et al., 2015).

Among such beasts, there are some groups in which well-known diversification processes can be exemplified, namely a clade of hominoid-related beasts, and a clade of insect-related creatures, both currently spread in the European and North American continents (Fig. 1; topology follows Gerelle et al., 2016). Basically, the appearance of natural barriers, as well as opportunistic exploitation of diverse ecological niches, could be the main causes explaining where such fantastic creatures currently inhabit (i.e., their geographic distribution); this would be in spite of the common explanation of climate change driving biodiversity dynamics (e.g., Janis, 1993; Alroy et al., 2000).


According to Gerelle et al. (2016), Fairies, Imps, Pixies, Grindylows, and Doxies form the sister clade to butterflies (crown-Lepidoptera), making them a sort of ‘lepidopteran-like’ beasts. Despite being phylogenetically related to insects, all creatures in this clade possess humanoid traits, consisting of a remarkable case of evolutionary convergence. In addition, the absence of wings in Grindylows and Imps is probably a case of reversion to the apterous plesiomorphic condition of insects (i.e., the insect lineage was originally wingless; Kukalová-Peck, 1991).


Figure 1. Current distribution of the groups discussed in the text with their phylogenetic relationships, based on Gerelle et al. (2016).

It is plausible to assume that the split between crown lepidopterans and lepidopteran-like fantastic beasts occurred back in the earliest Jurassic (Hettangian) of Britain (circa 200 Ma, i.e., 200 million years ago), as this is where the oldest fossil lepidopteran comes from (Whalley, 1986; Schachat & Gibbs, 2016). At that time, continents were united in a single land mass, called Pangaea, which would have allowed some populations of ‘Doxy-like’ beasts to migrate from British areas to what is now North America (Fig. 2A). This would explain why Doxies are present in both continents, but the remaining representatives of the group are not, demonstrating another case of disjunct distribution, as occurs, for example, with ratite birds, some pleurodiran turtles and flowering plants (Wen, 1999; de Queiroz, 2005). Otherwise, Doxies might have later migrated to North America through land continuities such as the De Geer Bridge (McKenna, 1975).


Figure 2. Probable location of ancestors of (A) the lepidopteran-like beasts during the Hettangian (earliest Jurassic) of Britain, with posterior migration to North America, and (B) hominoid-related beasts, originating in Central Europe during the Paleogene, with subsequent migration to northern Europe and North America. Maps modified from the Paleobiology Database (PBDB;

Grindylows branched early in this clade’s evolutionary history, “soon” after the Doxy lineage separated, likely dating to the Toarcian (late Early Jurassic; circa 180 to 175 Ma), when England was flooded by marine transgressions (Wignall, 1991). The populations occupying the deluged area probably vanished, while the ones remaining at its borders survived and later invaded the aquatic environment (organisms closely related to modern Grindylows). This is somewhat akin to the Pleistocene refuge hypothesis of Neotropical diversification (e.g., Vanzolini & Williams, 1981; Garzón-Orduña et al., 2014), but instead of forest retraction due to climate fluctuation, areas underwent fragmentation because of marine water incursion.

Like the other splitting events, Imps and Pixies diverged mainly due to historical causes. Both beasts share morphological and reproductive similarities (Scamander, 2001). Pixies are restricted to Cornwall, whereas Imps are distributed throughout Britain, living near river banks. In Cornwall, the River Tamar largely represents the boundary with the rest of England (Carey, 1911). The rise of sea-level (similar to that of the last interglacial period; Rohling et al., 2008), could have flooded the river region, isolating populations that lived near it (like modern Imps do). On the Cornish side of the river, a small population would have differentiated, preventing gene flow after the restoration of sea levels (Fig. 3). Despite capable of flying (and thus crossing the river), Pixies are not known to form hybrids with Imps.

According to folklore, Fairies are exclusively British creatures (Briggs, 1967; Silver, 1999), but the lack of information regarding ecological preferences (Scamander, 2001), as well as fossils, hinder speculation about their evolutionary history.

It is likely that, instead of historical events causing populations to split, ecological constraints were mainly responsible for the current diversity of hominoid-related beasts. The first branching lineage to be analyzed is the clade formed by Gnomes, Red Caps, and Leprechauns. As hominoid-related beasts, the group probably originated at least before the Miocene (a period spanning roughly 23 to 5 Ma; Stevens et al., 2013) and later invaded European landmasses. The burrowing habit of Gnomes most likely resulted of selective pressure due to the predation by Jarveys, a large ferret-like beast present both in Europe and North America. As such, the plesiomorphic (i.e., ancestral) condition of the group was a non-burrowing habit, which might have evolved independently in Red Caps too (Scamander, 2001). The occurrence of Gnomes in both Europe and North America depicts again a case of disjunct distribution, but the processes that drove such pattern probably differ from that of the Doxy. Rather than a vicariant event resulting from the split of Laurasia, climatological events could have created a passage that allowed them to reach North America (e.g., the Thulean Bridge; Brikiatis, 2014), as exemplified by marine diatoms during the Eocene (Bijl et al., 2013). As Jarveys intensively preyed on Gnomes, some populations likely sheltered in tunnels and acted as scavengers, feeding on the blood shed by their kin (similar to modern Red Caps).

In turn, Leprechauns likely represent a more recent lineage that migrated to Britain at first (still connected to the European mainland; Erlingsson, 2004) and then reached Ireland, probably across a land bridge before humans (Edwards & Brooks, 2008; Bower, 2016), being later included in Irish folklore (Winberry, 1976; Koch, 2006). However, Leprechauns (as all the exemplified beasts) lack a fossil record, which complicates the understanding of how and when such groups colonized the areas they currently live in (Crottini et al., 2012).

The other clade of hominoid-related beasts comprises Erklings, Trolls and Progebins, distributed in northern Europe (Fig. 4A). Modern representatives of the group are known to feed on flesh (especially human; Scamander, 2001), which evokes whether such beasts arose earlier or later than the Homo arrival to Europe (ca. 1.4–1.8 Ma; Parfitt et al., 2005; Toro-Moyano et al., 2013). Probably spread all over Europe originally, the competition for the same kind of resources (mostly raw flesh) with a distantly related clade

(Homo species) may have constrained the range of the group (mainly inhabiting densely vegetated zones today), extinguishing ancient populations more widely distributed. This last example analogously illustrates a case (e.g., Silvestro et al., 2015) in which the later arrival of a phylogenetically distant (but ecologically similar) clade to an area triggered diversification shifts onto the previous occupiers, as well as the probable extinction of some forms.


In order to verify if there is a regionalization among the fantastic biota, their geographical distribution was compiled from Scamander (2001) and interpreted based on (i) six distinct geographical realms from Wallace (1876), and (ii) the recent division of Holt et al. (2013) in 13 domains. Each creature was plotted against the realm in a simple area vs. taxa matrix (e.g., Souza, 2005), scoring (0) if absent, and (1) if present in a determined locality. This gives us a diagram, called ‘area cladogram’, with the biogeographic history of the groups.

The area cladogram obtained with Wallace’s six biogeographic domains (Wallace, 1876) is partially consistent with the biogeographical history of the southern hemisphere (i.e., mostly Gondwanan-derived land masses), according to patterns observed in some plants and animals (e.g., Sanmartín & Ronquist, 2004), in which the Oriental biota (i.e., mainly Indian) is the sister group to the remaining areas (Fig. 5A). This could be reasonably expected, since India was the first land mass to branch in Gondwana breakup geological sequence (Barron, 1987; McLoughlin, 2001). The relationships of African, South American and Australian areas however disagree with Sanmartín & Ronquist (2004), in which it was expected that South American and Australian biotas were more closely related to one another than to the African biota. This result could imply a Pangaean origin for these fantastic beasts, with subsequent vicariant events. However, this hierarchical pattern following the breakup sequence of Gondwana could also be a kind of ‘vicariance-mimicking’ phenomenon affecting the cladogram area topology (see Upchurch et al., 2002). Until fossils of fantastic beasts are found, knowledge about their past distribution remains obscured. On the other hand, when plotted according to the biogeographic realms of Holt et al. (2013) the Gondwanan-derived continents do not present such hierarchical relationship (Fig. 5B), resulting in a pectinate (i.e., comb-like) conformation within the area cladogram. Both results could also be influenced by the lack of data about the fantastic beasts, which may not follow the pattern of ordinary ones.


Figure 5. Area cladograms obtained based on (A) Wallace’s zones (1876), and (B) Holt et al. (2013) new zones, subdividing those proposed by Wallace.

In sum, due to the incompatible results for Gondwanan continents, the fantastic biota could have had a hybrid, composed origin (Amorim, 2012), with both autochthonous and allochthonous elements. The Palearctic and Nearctic realms were recovered together in both analyses, although both regions are inhabited by most of the beasts, which could have biased the result. Despite of the apparently unarguable Laurasian distribution of such beasts, it has been historically difficult to depict the continents’ biogeographical scenario (Sanmartín et al., 2001; Wildman et al., 2007).


Biogeography is an integrative science combining different sources of evidence to understand what caused organisms to be distributed the way they presently are – or were in the geological past (Lomolino et al., 2010). Despite of its relevance, the public knowledge (i.e., outside the academic environment) concerning this research area seems debilitated, even with the timid increase in electronic dissemination (Ladle, 2008). Present in both evolutionary approaches of Darwin (1859) and Wallace (1876), the spatial distribution of organisms offers an unparalleled tool to stimulate students to think about evolution and natural history (Rosenau, 2012; Allchin, 2014) – and not just to understand evolution, but to accept it as well (Lombrozo et al., 2008).

In this context, the teaching of biogeography (and evolution in general) could benefit from the use of fictional organisms with “real” distributions around the globe. Presenting the continents’ past and present arrangement, allied with the localities inhabited by the beasts and possible disjunction events, in a kind of inquiry-based approach (e.g., Robbins & Roy, 2007) would instigate students to formulate their own hypotheses. This, in turn, could lead them to more easily assimilate all these concepts. The specific use of the popular Fantastic Beasts of the Harry Potter franchise to canalize this is supoprted mostly by the interest of younger audiences (under 25 years old) in the recently released spin-off movie (over 50%; Lang, 2016). Actually, scientific scenarios were already present on several episodes from the Harry Potter books (e.g., Rowling, 1997; 1998; 1999; 2005), providing a larger background for people to get involved.

Moreover, this would not be the first time that a fictional universe was considered to engage younger people on scientific activities (e.g., Roque, 2016). J.K. Rownling’s fantasy novels are already proven as a promising and innovative background for scientific experiments (e.g., Vezzali et al., 2014). As such, the present work is hopefully in a good position to arouse at least a spark of interest among students to understand what made our beasts – fantastic or otherwise – to live where they do.
