Two non-chickens mated and the DNA in the new zygote (The cell formed by the union of a male sex cell and a female sex cell) contained the mutation(s) that created the first real chicken.
This is a chicken zygote, which you may recognise as a chicken’s egg.
The zygote cell is the only place where DNA mutations could produce a new animal, and the zygote cell is housed in the chicken’s egg.
So, maybe the egg came first?
I really like the photo. Where did you find it? :)

ReplyDeletealso, people found an egg of chicken older than the first chicken found in the world. So, the egg came first.
ReplyDeleteThe chicken came first from a undisclosed breeding process or program
