Does the existence of bears, especially the Panda, dispute evolutionary theory? The latter has allegedly eaten almost solely bamboo as long as we've known, with their earliest fossil goes back a million years. And yet while there's consequently a small difference in what is digestible to it, there is no radical difference in how it's digestive system functions, it's equivalent to lactase persistence or japanese seaweed gut germ. Similarly it's morphology is only slightly different from the other bears? Why has this guy hardly changed despite living in a radically different way? Even accounting for lack of predation on account of presumably being an apex predator in the past, would sexual selection not make a difference eventually? And other bears have similar , still-substantial (though less extreme) variations in their diet/lifestyle with little difference; the polar bear spends most of it's time near/in water and eats total meat, the grizzly is an oppurtunistic hybrid between a browser/predator and the sloth bear is an anteater wannabe.

No
>live where there is bamboo
>eat bamboo, develop to consume it
they're going extinct anyway, I used to have a geography teacher who said it served them right for developing to be only able to eat bamboo.

There's been an uncountable number of species in the earths history, the vast majority of which have become extinct for one reason or another, lots of which were just evolutionary dead-ends. That doesn't "dispute" evolution it just means that adaptions which lead to that species eventually died off for whatever reason, including changes in the environment which placed them at a disadvantage.

Pandabros make it make sense
