Because I thought my grip of science was pretty firm but she's got me all . She says she doesn't believe in dinosaurs (me: why not? We have seen the skeletons, they lived a long time ago...DD: well it all seems very unlikely doesn't it. She's not wrong!) And now she wants to know if the monkey-things evolved from the dinosaurs, and I am wondering because I know birds did and presumably lizards did, but did mammals? And where do fish crawling out of the slime on their fins fit in? And there were mammal things about at the same time as dinosaurs - like, mammoths and sabre-toothed tigers (?), but did they share an ancestor?
Anyway. I think a book, clear explanations, preferably with things saying and we don't know how this bit happened rather than making anything up (!) and some nice bright pictures, would be very useful. Is such a thing available?
