Wouldn’t that make a great name for a band? Rather to my surprise, I’ve discovered that ‘sarcastic fringeheads’ are actually…

talking about exaptations
During a lecture to our second-year evolutionary biology class I introduced the concept of exaptations: features that have evolved in one environmental context but which have been co-opted to fill a different role in a changed environment. This was in the context of swim bladders/lungs, which I’ll talk about in a minute, but right now […]
Continue readinganother lovely biological image
Grant & I have something of an ongoing friendly competition to come up with stunning & unusual biological images. Here,via PZ (as usual!) & The Node is my latest offering: It’s a confocal microscope image of a squid embryo. The reddish areas are neural tissue (mmmm, braaaainzz) & each of those fluorescent green speckles is a tuft […]

My sea cucumber, that is. I was going to write something full of snark about the current brouhaha around predictions that the world is going to end on May 21st. But Darcy has beaten me to it! So instead (from the Echinoblog, and via PZ) I offer you… [drumroll]… the sea cucumber with fish residing in its nether […]
Continue reading‘darwin’s dilemma’ – id in nz
A little while ago Ken alerted me to an Intelligent Design website that appeared to be set up to provide ID ‘resources’ to teachers & others who might be interested. Today I found time to wander over & have a look at what was on offer (not much, at the moment). The site’s owner is […]

I’ve just started browsing through a book with the promising title, Quirks of human anatomy: an evo-devo look at the human body. (Held, 2009). (The Science librarian does a great job of sifting through new titles & running them past the various departments in our Faculty to see what people would like to see added to […]

Because I seem to have very little time on my hands at the moment, I thought I would re-post something I wrote very early on in my blogging career – it hasn’t dated & in fact is quite relevant to a more recent post on ‘intelligent design’ creationism The camera-type eye of humans (& in […]

With the new house came a long drive lined with agapanthus. My mother would have said, "the dreaded agapanthus", & she wouldn’t have been far wrong. I don’t like the things very much; they spread very vigorously & I tend to view them as a weed. (I see from Te Ara that Biosecurity New Zealand was […]

Well, I’ve just got back from a series of conferences (3 in the space of 10 days) – & all of them about teaching! I was getting pretty tired by the end of it all, but at the same time it was really good to be able to spend time talking about teaching (& about […]
Continue readingAlgae & isopods – a unique symbiosis
When I set essays for my first-year students to write during the semester, I try to give them a scientific paper on each topic to start them off. This means that I need to do some extra bedtime reading as I need to select those papers carefully. Today’s post is based on one of those: […]
