Depends on what you define as “lasts forever”. We are direct descendants of some kind of a rodent. Yeah, our species has changed “kind of much” since those days, but I wouldn’t worry about that kind of “expiration”. We are some rodents’ grand-grand-grand-…-grandchildren, and I think the rodent would be very much okay with us not looking very squirrellike, if they somehow was to find out they are our ancestor. They’d love us all the same :)
But of course, in our case, it won’t be that evolution changes us into something else. It’s rather, we will just vault 92’ify ourselves.
