After you are done reading this, your thinking will never be the same.
According to the thery of evolution, two living creatures of close to the same DNA mate, to create a different yet simeler creature.
I actually spent about 4 months of constant research in an attemtp to understand and correctly answer this very question.
Most of the antiant creatures laid eggs as most where lizzards and fish (Putting it simply).
But there where a few mammles who did not lay eggs. But was it a lizzard, or a mammle? Or is a chicken both?
The humble chicken is classified as a bird, but how was the bird made?
Half way through my research I came to an answer. The chicken has reptialian skin, but the features of a mammle. Logicly, that says that it was a cross between both...
The thing is, was the female lizzard, or mammle? If it was mammle, then the chicken was born dry, thus coming first. But if the female was lizzard, then the chicken would have been born as an egg.
Any creature gets 66% of its mothers features, thus, whichever it had more of, would be the mother.
Taking that into account, I figured out that the chicken has more mammle then lizzard. The only lizzard features it has, are skaily feet and lays eggs. However, its skin, eyes, movement, matting patterns, and beak came from a mammle. Thus, its mother was a mammle.
Therefore, the only logical thing to conclude is.....
The chicken came before the egg!
