@WatchyaSamantha Why haha
Some animals are puuurfect as is and don't have to evolve 💪
We hoomans have still a looong way to go 
@stux Science nitpick: These are not prehistoric creatures. They are very much modern animals.
And no, they are not the same animals as those that lived millions of years ago. These animals evolved and changed. It's just that the outward look of this particular specimen evolved to be similar to what we think some prehistoric animals might have looked like.
TL;DR: There are no prehistoric creatures alive today. If they are alive, they aren't prehistoric.
@TatiMarrone @stux That's what I'm saying: there isn't minimal change. There has been minimal change in its outward appearance. The animal itself is for sure very different.
We should note here that form and outward appearance does not say much beside that it's evolved to fit a certain niche. And plenty of unrelated animals have evolved to look very similar because it ended up being advantageous for a class of niches. Most notable here is carcinisation: https://en.wikipedia.org/wiki/Carcinisation
