Yesterday one of the students in our 'Evolution' paper commented that those of us teaching the course were 'deifying' Darwin, which he felt was not a good thing. And if we were, it wouldn't be. To deify someone (or something) means to set them up as a god and worship them. And I can't think of […]

Is evolution a random process?
Evolution is often characterised – particulary by those who argue against it – as a random process which could not possibly give rise to the complexity and diversity of life on Earth. How true is this?

Here's a question for you. In 2006 scientists announced the discovery of a new hominin fossil: a juvenile Australopithecus afarensis. The media quickly dubbed it "Lucy's child" (well, it was a catchy name, even though the underlying implied relationship had no evidence to support it!). So, tell me, how could scientists be sure that this individual was an […]

At the moment I'm lecturing to our first-year biology class about plants. In my lecture about algae, there were a couple of slides about malaria. You might well ask 'why'; I know my students were thinking that. Well, I did have a reason – & today I found a brief summary paper (Keeling, 2008) on just […]

The new Science curriculum has the 'nature of science' right up there at the top. And why? Because it's so important for people to learn, not just science facts and concepts, but also about what science is: how it's done, the tools and methods scientists use, how they communicate, its history, & how science is […]

Some clever person out there has written a programme that checks a blog’s reading level – I guess I’ve got it about right… (though I’d be glad to hear what you think about that!) What is Website Reading Level and Why Does it Matter?

Orac's just blogged on a new study that seems to show that heavy cellphone use contributes to male infertility. No doubt this will be all over the headlines in a day or so – so I thought I'd get in first & give you some practice in critical thinking while I'm at it.

The 2005 Schol Bio paper included the following question. The three examples shown represent just some of the diversity found in bony fish. Use the diversity of the fish and/or any other named group(s) to discuss the following statement: 'Diversity is the end product of evolution.'

Here's a link to a set of articles that summarise talks on various aspects of evolution research. They're straightforward & easy to read, & should give you some interesting additional background to some recurring questions.

Those of you who've come to one of my Scholarship preparation days may have noticed that I've got a bit of a bee in my bonnet about pseudoscience. It really annoys me when I see science being mis-used to sell a product or promote a particular point of view. A good friend of mine has […]
