Which came first,  the chicken or the egg?
The age-old question of whether the chicken or the egg came first does not have a clear answer. From a biological standpoint, the egg must have come first, since it is the product of genetic mutations in a previous generation of birds. However, the egg would have needed to be incubated by a chicken or a bird-like ancestor to hatch and produce the first chicken. Therefore, one could argue that the chicken came first, as it was the first to hatch from an egg that contained the genetic mutation that defined it as a chicken. Ultimately, the answer to this question may be a matter of philosophical interpretation rather than a clear scientific answer.
