i dont like semantics .. i am regressing them.
its how some scientist are planning to reintroduce the auroch using modern cows to selective breeding to bring the original back.

think of it as forks in the road that branch out and then merge again.. some are dead ends some go completely different direction and some curve back at a junction point.
The hope for its resurrection now lies in its tame descendants, domesticated cattle. Here's how the process is expected to work: Scientists will first scour old aurochs bone and teeth fragments from museums in order to glean enough genetic material to be able to recreate its DNA. Researchers will then compare the DNA to that of modern European cattle to determine which breeds still carry the creature's genes and create a selective-breeding program to reverse thousands of years of evolution. If everything goes as planned, each passing generation will more closely resemble the ancient aurochs. "Everything will be put together in a genetic mosaic," says Donato Matassino, head of the Consortium for Experimental Biotechnology in Italy and one of the scientists involved in the project. "Once we have all the roads, we'll try to follow them back to Rome."

Right, i understand what they're getting at, but it wont work. The key word there is mosaic, they'll just end up with some artifical hybrids that resemble the dead species. Besides, their echological niche is gone, they'll never bbehave like the original extinct ones did. It's just jurassic park wishfull thinking. Sadly, extinction is forever.
Been reading about crossing humans with monkeys but most attempts done have failed as monkeys have an extra chromosome than humans but Also read that downsyndrome humans have an extra chromosome also, so think some one should try crossing a downsyndrome with a monkey..lol You never know maybe it would work even though different types of chromsomes!!! In all humans chromosomes 2 and 4 have merged together and in apes they are seperate so they have one extra than us,, in Downsyndrome ppl they have an extra copy of chromosome 21 making them have the same number of chromosomes as monkeys. Monkeys like all healthy humans have one chromosome 21 but as downsyndrome humans have an extra copy of chromosome 21 it makes the total number of chromosones the same maybe that would help in cross breeding them. ...But surely someone must have tried this before if they haven't then they should try...!!
Just thought it was an interesting idea and wanted to share it even though ethically questionable but could work better than trying to cross a healthy human with one less chromsome than an ape.
