My brother asked that I post his most recent video about natural selection and common descent here for comment. He made it a point to separate in the video what is factual, and what is theory and I think he did a fair job of that. Are there any parts of this video that you think misrepresent important information on the subject? Thoughtful criticism is welcome.
Thanks!

Natural Selection and common descent
Re: Natural Selection and common descent
I think it is well done.
Like all evolutionary presentations, however, it seems to make the leap from the fact that some species share a descent from a common ancestor to the wild speculation that widely different types of living things (e.g., plants and animals; protozoa and metazoa; fish and birds, etc.) also share common ancestry with all others. This extrapolation is both undemonstrated and unlikely.
