While doing a bit of tidying in my office (a mammoth task!) I came across a printout of Jonathan Wells’ infamous list, "10 questions to ask your biology teacher". Wells is a senior fellow with the US-based Discovery Institute, which actively promotes intelligent design as an alternative to evolution. His list of questions is (I […]

brain food
Your brain is an energy-hungry organ – even when you’re resting, it can use up to 25% of available energy (chimp brains use about 8%: Gibbons, 2007). In other words, the running costs of a large brain are quite high. And yet humans, with their large brains, take in about the same number of calories […]
Continue readinganother bit of creationist misinformation
Some of our local letter-writers are quite busy at the moment, pouring out their opposition to the fact and theory of evolution. Sometimes they seem a bit confused about how evolution works, but at others their letters contain an awful lot of misinformation… [An earlier writer] managed to take the ploy of elephant-hurling (in debate) to new […]
Continue readingtuskless elephants – natural selection & genetic drift
In an earlier post I mentioned that natural selection (hunting pressure) had the potential to increase the proportion of tusklessness in African elephants. But I also noted that this was probably not the full story! And in fact it turns out to be quite a complex tale.

James Burke was a wonderful science communicator (still may be; I don’t know if he’s still alive). Twenty-something years ago, I remember watching one of his TV series, The day the world changed. It impressed me then, & I wasn’t disappointed when I watched part of it again today, having found a link to it via […]
Continue readingwhy you should study evolution
I’ve just been talking with some of my students about evolution: fact, theory, process of, the whole lot. And why it’s important that people learn about it. I wish I had seen this piece by Olivia Judson beforehand – I could have referred them to it there & then. And because she says it so […]
Continue reading‘the genius of Charles Darwin’
PZ has just posted the video The Genius of Charles Darwin on Pharyngula. It’s fronted by Richard Dawkins, & his intention in making this film (part of a series, by the sound of it) is to look at who Darwin was, how he developed the theory of evolution, what that theory is – & why it […]
Continue readingenvironmental change and evolution
I was talking with a senior Bio teacher a few days back & she said it would be good if I could deconstruct some of the questions in 90717 (patterns of evolution), as this was an area where her students seemed to have difficulty. I’m not exactly going to do that here. But one of the […]
Continue readingpopulation genetics of A1 & A2 milk
This is an item I originally wrote for the Science on the Farm website. But because I briefly mentioned the A1/A2 milk thing in the last post, I thought I could usefully bring this across to the Bioblog as well. The 2006 Scholarship Biology paper included a question on the genetics of A1 and A2 […]

The Wild Side is by writer & evolutionary biologist Olivia Judson – it’s her blog in the New York Times. (She also wrote Dr Tatiana’s Sex Advice to All Creation: the definitive guide to the evolutionary biology of sex.– a really good book full of great snippets of information about the weird and wonderful ways of […]
