I’ll type slowly this time for you: the thing we call “chicken” came about from a mix of genes from parents which weren’t exactly what we call a “chicken,” and yes, this kind of “evolution” does happen in real life, but too slow for humans to follow or make the connections.
Just as modern wolves, horses, and many other mammals have NO representation in the paleological records past a few tens of thousands or hundreds of thousands of years, but similar animals do.
What came FIRST was the egg, containing the completed - or close enough for chinese food - chicken.
It doesn't seem to be worth arguing. Who cares about chickens? Then again, the question has nothing to do with chickens and is why people tend to get into arguments about it. Its political and the conclusion a person comes to and the way that person thinks that brought them to that conclusion is important.
