OK, it’s cute and catchy, but it’s also got a very awkward sudden jump from the mammal-like reptiles to the primates, and unfortunately it perpetuates the “evolution as a process on rails” concept by showing a single lineage — ours, of course. Why not show a progression to a modern rose, or a fly, or a fish? Or better yet, illustrate evolution as an ongoing explosion of diversity? I know, I know, it isn’t as engrossing to self-centered humans, the market for this sort of thing.
