Re: embryo research what is it and how useful is it to extinction

Anthony:

Embryo research refers to any work on the early development of animals, whether 
worms or flies 
or human beings. I think you probably meant to ask about embryonic stem cells 
(ES). These are 
cells that are found in very, very young embryos when there are only a few 
hundred cells. ES cells 
are able to give rise to all the different cells of the body. There is a strong 
possibility that human 
ES cells could be used to replace cells that die in diseases like Parkinsons 
Disease or Alzheimer's 
Disease. But, as you may know, making human ES cells is very controversial, 
especially in the 
USA. 

I'm afraid that they won't be any help with extinct animals. Once an animal is 
extinct, that's it - 
no more animal. It is why it is important not to let any organism go extinct - 
it will never, ever 
exist again.
