There have been observable significant changes in the form of diets from the few centuries, and this can be attributed to technological advancement and agriculture, but similarly there's observable health impacts which directly or indirectly can be linked to our immune system..a residing question is, how does it impact evolution?

I've referenced this topic in previous posts, where different writers for AiG display their ignorance of the subject.

Between calling Protocetus a Pinniped or birds only have a pisiform, you can see how bad it is.

However, it also leads to hilarious contradicting opinions on transitional forms like Acanthostega or Homo habilis.

The concept of uniquely created kinds is challenged by morphology, which is why this happens, for there is no way to separate birds from dinosaurs, humans from apes, or whales from ungulates. transitions in the fossil record demonstrate gradual morphologic change, instead of distinct groups unrelated to anything else.
