I wish I'd found this page earlier – you might have found it interesting in preparing for your exams. It's a series of images pf reconstructed hominin faces, & a linking story about them. (There's actually a whole book about them – I bought myself a copy earlier this year & I'm enjoying dipping into it now & then.)
The faces have been reconstructed using the same techniques that a forensic anthropologist would use when faced with a fleshless modern skull. OK, there's poetic license here – we don't know what colour their eyes would have been & how much or how little fur they had. But wonderful illustrations nonetheless – they really open a window into our past.
