310 - "A fertilized egg is a human being. "

Sorry, I can't agree. It is a fertilized human egg.

A human being, it is not. Remember, was it Descarte? "I think, therefore I am".

An egg is an egg, and a chicken is a chicken. They are not equal. I don't enjoy "Southern Fried Eggs" or "Ham and chickens, sunny side up".

Again, once that chicken egg is fertilized, at what point is does it become a chicken? It is undoubtedly a chicken when it hatches and a little before that and a little before that...

I think you can see that any arbitrary cutoff point can be shown to be false until you get back to the point at which the parents' DNA joined. There's nothing magic about it. In fact I've eaten fertilized chicken eggs and they taste exactly like unfertlized ones. There's just a microscopic chicken within the yolk.
