Er...we have zoos, and we already don't always know what diets are best for new and exotic creatures.Doclector said:The question stops being one of safety and one of morality. Who are we to raise these creatures out of their own time? Could we make a good life for them here? Do we even really know what they want? Archeologists have worked at figuring out their diets and enviromental needs, but when speaking about a creature that hasn't ever been observed alive or even recently dead, we cannot be sure.
The crucial point is: What could we gain? Certainly efforts will have to made to ensure proper treatment, but would what we stand to gain be worth the risk that we can't care for these animals properly? I'm not sure. The gain to what we know for sure about prehistory could be massive, but what could we do with that information? Can we risk grossly mistreating these creatures for the sake of mere scientific curiousity?
I see no fundamental difference.
Yes, we can absolutely 'risk' animals living on shitty diets until we figure out the right diets if it means a far deeper understanding of our own evolution and the evolution of birds and reptiles.
In fact, being able to see first-hand which detrimental genes were active during the time of the dinosaurs would be hugely beneficial towards understanding how to treat such genes that exist in today's humans and birds and other mammals.
