Who comes first the hen or the egg?

Answer 1

The egg. There were eggs LONG before there were hens.

Dinosaur eggs, reptile eggs, amphibian eggs, fish eggs, etc.

Answer 2

The hen, with the egg inside.

Answer 3

Once the egg has been formed, it grows by simply mitotic cell divisions to maturity. In such divisions, the DNA is copied exactly (almost) - and any mutations would only affect the single cell in which they occurred, and would not affect the whole chicken.
The formation of the egg, however, is by meiotic cell division, which can introduce a whole range of genetic transformations into either the ovum or the sperm. Any mutation here will affect the DNA of the initial zygote, and therefore every single cell which grows from it.
It is therefore certain that an egg will grow into a chicken but it is not certain that two chickens will mate and produce another of their species!
The egg therefore came first - as the first chicken was produced by two parents who were not-quite chickens!

Answer 4
