What came first?

[TWR]

The chicken or the egg/ Is there an answer?

[ABerrant]

Not only chickens lay eggs.

Well I normally have egg in the morning for breakfast and chicken in the evening for tea. I wouldn't have chicken for breakfast. Therefore, in my book, the egg comes first.

The chicken came first or at least a bird resembling a chicken. The theory of evolution states that species change over time via mutation and sexual reproduction. Since DNA can be modified only before birth, a mutation must have taken place at conception or within an egg such that an animal similar to a chicken, but not a chicken, laid the first chicken eggs. These eggs then hatched into chickens that inbred to produce a living population. Hence, in this light, both the chicken and the structure of its egg evolved simultaneously from birds that, while not of the same exact species, gradually became more and more like present-day chickens over time.

Chicken starts with "C". Egg starts with "E" So alphabetically .....

[woofgang]

didn't the prehistoric ancestors of the chicken lay eggs?

[JonnyBoy12]

Roosters don't lay eggs; they lay hens!

[FredPuli43]

Depends how you define a chicken. The egg from which the very first chicken chick hatched was there before the chicken.

I'm with Woofy. Dinosaurs laid eggs but they didn't contain chickens so. .
Egg first

[Ellipsis]

The egg came first. It was laid by "not a chicken". It was a mutation, making it not "not a chicken", i.e. a chicken.

I think it has to be the chicken and partner - created dare I say it. There was a chicken and it laid an egg. If the first thing was the egg, then the egg would have had to be laid by the chicken and fertilized by the cock. Simples.

The egg. From the primordial soup, invented by a Russian and adopted by Darwen. How would a chicken run out of there ?

[RATTER15]

The cock!
