I bet you have heard the old question, “Which came first, the chicken or the egg?” I never really thought that was a very hard question. My answer to that question depends an exactly what the question asks. You see, it would have two opposite answers, depending on what kind of egg was in question.
If the egg in the question is to mean any type of egg, well then the answer is simple. The egg came first. But, if the egg in the question was meant to be a chicken egg, then the answer is also simple; the chicken.
Let me explain my reasoning. If it is any egg, then there were many animals that used eggs as a way to procreate way before there was a chicken. So eggs came way before chickens.
Now, if the question means chicken eggs; there has to be a chicken to lay a chicken egg. The chicken’s predecessor on the evolutionary tree somehow laid an egg that turned into a chicken. I don’t know what that pre-chicken bird was or what the father was, but it was at least one gene away of being a chicken. So the chicken came first before the chicken egg.
Any arguments, other opinions; let’s hear them.
Now for the next age old question: Why did the chicken cross the road???
