I spent yesterday up in Auckland, running a schol bio preparation day. (And thanks to Mike, Cindy, BEANZ & the Auckland Science Teachers Association) for setting it up.) I do enjoy these sessions (& hopefully the students do too!) as I like the interactions with students & they always ask nice, challenging questions.
Anyway, after we'd finished the main proceedings of the day, someone came up & asked if I'd heard of the 'killer Neandertal' hypothesis, & what did I think of it? Was it a good explanation for the evolution of modern humans? The quick answer was, no I hadn't, so couldn't really comment - but I'd go & have a look :)
