Hi Linear -- it's busy here.

Bex, I'm going to have to narrow the topic of conversation because I can't spend hours on posts, but I'll have a proper read of yours later. I think you misread somewhere what I said about brain size being relative to body size and that it is NOT an absolute measurement.

I'm sat in my Year 9 class while they have an extended reading period and I've just read an interesting article about brain size and evolution on the BBC news site, which I wanted to share here because it's what I've been talking about. The mysterious brain . . . if I were a scientist, I'd have a difficult time choosing between studying consciousness and studying human evolution -- both of them fascinating.

This article talks about new advances in our understanding of the complexity of the brain, and that size is NOT everything, though it still obviously has a part to play. There's just a lot to learn still, which is what makes this such an exciting thing to study.
