Explanation of Human Ancestry Made Easy

So a few years ago Potholer54 made a video series pretty much explaining the history of the earth and life and one of those videos was Human Ancestry Made Easy. He apparently got some questions about some of the content. Now I use the term questions loosely here because it is pretty obviously creationists trying to show that evolution doesn't work, even though it does and they are wrong. I think the bigger issue is just the way Potholer54 phrased the statement and he at least tries to explain it here, although I don't think he did a perfect job with it either but he at least got closer.
