Something i have never understood.

Oh ok thanks just me being stupid lol

Thanks for the replies

As a good friend of mine told me once, "If you're confused it means you're thinking."

A'int nothin wrong with thinkin'. :)


Edit: Also, here ya go: http://www.bcreptiles.ca/reptiles_north.htm

They haven't adjusted to our temps because we replicate their natural necessities. SO they can't adjust if the temps at which they are kept are the same as back home.

This is a simple concept with a long drug out explanation. Think of it happening in nature. When a species attempts to migrate to a different climate they do it at a very slow pace. probably only a hundred miles at a time, maybe less. Once in the new area some die off because they cant handle the extreme change of a few degrees. Those that dont die woudl then have to breed multiple generations. Mother natures selevtice breeding of an animal that can stand the new areas conditions. then they move a bit more, selective die off, selective breeding, and so forth. Would take many many years to change even in the wild. Being captive bred we keep them in their native temps / humidity so there is no selective die off or breeding being done to promote the change.

Short answer: Because Evolution isn't instant.

For a cold blooded animal to change their requirements would take hundreds and hundreds of generations. Mammals are infinitely more adaptable than reptiles. And we still have strict requirements.

Yup, what they said.

We,ve been breeding fish in captivity for thousands of years - they still need water.

You can breed all the penguins you want in Death Valley...they still need to be kept cool. You can also breed homo sapiens in space, but they still need oxygen. Extreme examples? Yes, but you get the point...
