This is a comic about evolution: there's a framing story in which aliens talk about evolution on earth. I know some evolution. Some stuff I learned has since been shown wrong. I don't know all there is to know about evolution. But this book wasn't a great way for me to "catch up". If I tried to skim past parts that I already knew, then I'd miss out on parts of the framing story. So... this might be a good comic book for kids. But for geeks of a certain age and education, it might not be so great. (I think it's aimed at kids, so that's OK.)
