One of the questions students often ask, when we’re discussing human evolution, is “what happened to the Neanderthals?” After all, this was a large-brained species closely related to our own, with some fairly complex tool technologies and the ability to survive (and thrive) in harsh environmental conditions. Yet they appear to have been replaced by […]
Continue readingMy interest in kākāpō way back in my honours year at uni: a guest speaker told us that as far as anybody knew, the last remaining birds were a few males, somewhere in Fiordland. I remember feeling that that sounded really sad – those lonely males booming for females who never came. Shortly after that, […]

(Or something along those lines.) I’ve just come across another one**, & thought I’d write this post as a warning to year 13 biology students. As Carl […]
Continue readingBy the end of the school year, year 13 students preparing for Schol Bio should have a pretty good grasp of the concepts & content they’ve encountered in their studies. What tends to throw some, though, is the fact that the context used for each question will almost certainly be something that they haven’t come across […]
Continue readingLast week the story of a hybrid hominin was in the news: the discovery that remains found in Denisova Cave were those of a 13-year-old girl whose parents were a female Neandertal and a Denisovan male. This was exciting stuff: we already know, from genomic analysis, that interspecies matings involving Neanderthals, Denisovans, and H.sapiens happened […]

But I don’t think that’s what happened on the occasion reported under the headline Creationism taught in science class at Villa Education Trust school: [A student who’d studied at] Mt Hobson Middle School said Darwinism was taught as an unproven theory and students were shown […]
Continue readingI've always rather liked ducks, ever since we hand-reared some ducklings back when I was still a school-kid. Mind you, the innocent me of those days didn't know what I know now about the effects of sperm competition and sexual selection on their reproductive organs. (Those of an enquiring mind will learn more – much […]
Continue readingI was idly skimming the Herald's website when I came across an article with the headline "Is plant medicine really that effective?" Since the article appears to be in the nature of an advertorial, the answer is, it depends on who you ask. Unlike man-made chemical drugs that have been developed as novel medicines from the 19th […]

I’m starting to gear up for some Schol Bio preparation days in the regions (hi, Hawkes Bay! See you in 4 weeks!) and realised that I haven’t written anything specifically focused on those exams for a while. So I thought that putting something together would be a good way to spend a rather wet Sunday. […]
Continue readingPangolins are strange little creatures, with their diet of ants and termites, and the entire outer surface of their bodies covered with armour-like scales (face, belly & the inner surfaces of the limbs are either hairy or naked). When in danger, pangolins are able to roll up in a ball, presenting only that armoured surface […]
