> If we started a human-directed breeding program to develop chimps capable of language (arbitrarily chosen marker of intelligence) right now, I would guess we might be able to cut that time down to merely hundreds of thousands of years. Another option is to pick a collection of human genes that seem like they may be relevant, and just insert them into chimp genomes. Followed by something like your selective breeding program. I would be fairly surprised if it still takes 100k years.
