Every time I'm out in nature looking at the birds, snails, frogs, fish, plants and other wildlife I get this 2 part question going on in my mind. 1. On a planet like our own in orbit around a sun not unlike our own.. would the wildlife have similar features? Would there be "robins" and "thrushes" and eagles... carnivores, and herbivores and would the squirrels have the same tail or would there be squirrels at all? 2. If an extraterrestrial person came to our planet, would all of our wildlife and natural environment seem familiar to them? Or would they not recognize most of what we call the "great outdoors"? If there are some answers among you, as speculative as you like... but based on scientific observations and calculations... please enter them here! Thank you.
