Wow, that’s tough.  But one animal that I think you might like to consider is probably chimpanzees.  It’s generally thought that humans share a common ancestor with chimps about 7 million years ago, and I think they’re a very intelligent species.  They have opposable thumbs, they’re not too bad at technology, and their population has grown in the last century.  And chimps have good long-term memories.
