The world itself hasn't actually changed as much as you may think. The majority of changes that have been made are on the part of humans changing the world (terraforming, basically, so that it suits them more). There's been no major ice ages or meteor storms, or anyting like that for quite a while now.

Also, crocodiles have lived through two ice ages.
