And there is evolution to take note of too. The chickens that were alive back then could look very different to the chickens we have today. We say the word “chicken”, and we think of the chickens that you see at farms, or sometimes in the wild, with no thought at all to the details. True, one could argue that chickens have not undergone any evolution, and were as they are today, but there are several flaws in that reasoning. First, every animal has been a certain way, but, as time passes and their environment changes, they must change as well. Here’s an example of natural selection, for those who are not as well versed in the matter of evolution.

Say there are white squirrels. They have lived there for hundreds of years, and therefore adapted to accommodate the forest. One day, a paper mill is built next to the forest where they reside, and spews pollution out. Over time, the trees of the forest, once elm white, are not soot black. The white squirrels are then hunted because they can no longer blend in with their environment. Soon, black squirrels are born. They can now blend in with the trees, and are killed less often. The white squirrels are hunted until there is no more left.
