Considering the year, and having read this today (particularly this quirks and quarks broadcast wherein the researcher proposes that crocodillia once occupied many of the niches we currently see mammals occupying), I've decided to spark up a discussion on the system of evolution by natural selection in Tyria. Does this system even appear in Tyria, ie. is there evidentiary support? How does magic affect this process? Are the legends regarding the origins of species metaphorical, misinterpreted or literal?
The game takes a rather interesting 'what-if?' approach to evolutionary dynamics. Almost every form of life we have classified on Earth is represented by a sentient group in Tyria.
This thread will take some time to compile, so I shall post an incomplete version and expand based on my own conjectures and those of commenters.
Let me start with the 5 races:
Human: Closest relative species on Earth: Homo Sapiens. If Tyrian Humans followed Earth Humans through evolution, primates would be their closest biological ancestors. Three obvious groups of primates have been encountered in Tyria: Grawl, 'Tusked' and 'Simean'. However, Humanity did not first appear on the continent of Tyria nor Elona. Cantha is noted as the first place Humanity was witnessed. Only one primate, besides Human, exists on Cantha: Yeti. Outwardly, this is suprising, but they are referred to in this quest as 'knuckle-dragging primates'.
Norn: Closest relative species on Earth: Homo Sapiens. The implication in the Official Wiki is that there is an implication that the Norn are related in some way to Humans. This would suggest either a direct genetic descendant of Humanity or an earlier convergent splinter from a different set of primates, the only primates found on the continent of Tyria.
Charr: Closest relative species on Earth: Feliformia. The Charr are something of an anomaly in Tyria. The only other Felines in Tyria are charmable animals, taking the exact name and form of big cats found on Earth.
Asura:Closest relative species on Earth: Some kind of Subterranean Rodent. Classifying the Asura is tricky. It's inspiration is clearly The Brain, but I'd like to understand what environmental pressures would give the Asura their characteristics. Small, pale, large eyed, and carnivorous.
Sylvari: The Sylvari are an exception, but still one worth exploring. We've seen their origin. The assumption is that magic plays a large role, if not the sole role, in their creation, but it's possible this is merely a misinterpretation. Plants, in Tyria have followed evolutionary tracts to achieve sentience. The adoption of an anthropomorphic form is puzzling, though.
Now let's look at the other races of Tyria:
Tengu: The Tengu display one particularly notable hallmark of the evolutionary adaptations we see in birds today: Plumage. Caromi, Sensali, Avicara, and Quetzal "tribes" all display different plumage. Most likely to blend with the environment or for courtship purposes. The likelyhood is that the Tengu have closer genetic ties to the Raptors of the Tarnished Coast than with any of the charmable pets.
Naga: The Naga population—water-dwelling creatures related to sea snakes which evolved a culture at peace with humans. On Earth, the Niuean sea snake; which must breed on land; represents a precedent for amphibian Naga descendant from sea snakes.
Fish: The Fish of the Jade Sea shed light on the role of Magic in the evolutionary process. Taking to land so quickly seems impossible. There are two possible causes: 1. These creatures existed before Shiro's Death Wail. 2. Magic acts like radiation, rapidly mutating the creatures of Tyria. If Magic acts like radiation, large numbers of fish were mutated upon Shiro's death. Those that mutated beneficial traits survived and bred into the Fish we see now.
Forgotten:
Dredge: Closest relative species on Earth: Belsmols.
Centaur:
