I think the work done by Cambridge University scientist on Nemotodes counteracts the argument that DR was making in that debate.
The Nemotode was the first creature to have it's DNA mapped (man was the second).A Nemotode is a microscopic wormlike creature one of the earliest
that have evolved.Scientists were able to identify a gene that effectively gave the Nemotode no control over it's body.They then inserted the entire
Human DNA and the Nemotode regained it's control.
Why would the Human DNA contain within it a gene that enabled Nemotodes to regain control??
The answer is very simple.As all species evolve they never discard their ancestors DNA,they merely build on it.Our DNA contains that specific Nemotode
gene because,frightening as it may seem,what we have decended from had a need for it.
