The world of Ark is filled with fascinating creatures that have hatched from eggs found in the mysterious Egg Cave. The original indigenous tribes of Ark left behind a profound legacy: they were able to mathmatically calculate some of the points at which creatures would evolve into more powerful ones (the equation is different for each species). They also recorded other pertinent facts too. This is all the information that has been gathered.
Since the original tribes are now extinct, data on newer species have not been gathered. The original tribes of Ark painted each creature in the Egg Cave but, unfortunately, most of them have eroded from the cave walls. Scientists are working regularly around the clock at the Science and Research Center in Ark City to rediscover the mathematical equations the original tribes used to help formulate newer ones.
There are total of 621 species currently discovered and documented in The Archives.
