The embryo is present at five to six days after the zygote is fertilized. The embryo is a clump of cells inside the formerly hollow blastocyst, and is surrounded by the trophoblast. The trophoblast contains cells that direct hormone production and implantation. After the embryo forms, the cells form the embryonic disk.
That is, two non-chickens mated and the DNA in their new zygote contained the mutation(s) that produced the first true chicken. That one zygote cell divided to produce the first true chicken. Prior to that first true chicken zygote, there were only non-chickens.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, the egg must have come first.hat is, two non-chickens mated and the DNA in their new zygote contained the mutation(s) that produced the first true chicken.
