Which came first, the chicken or the egg?

Thanks to Charles Darwin, we now have an answer to this hoary old chestnut:

Species evolve from other species over time. Because evolution is a mostly slow and gradual process, it is difficult—bordering on impossible—to state categorically when one species actually becomes another. It's a bit like trying to state the precise point at which red becomes orange in a rainbow. Different people will have different views.

But one thing is for certain: however you choose to define a chicken, if you go far enough back in time in the avian 'family tree', you will come to the first ever chicken. That first chicken's mother was undoubtedly a bird very similar to—but not actually, according to your definition—a chicken. And this chicken-like bird laid the egg from which the first chicken hatched.

So the egg came before the chicken.
