The hominid known as “Ardi” (a specimen of Ardipithecus ramidus) was discovered in 1994, at a site near Ethiopia’s Awash River. Once excavated, it turned out that this was – for its age – a remarkably complete specimen: 125 fossilised bones, comprising most of the skull, teeth, hands & feet, pelvis, and the lower sections of the arms & legs. This … Read More

Giant pandas (Ailuropoda melanoleuca) eat bamboo and not much else. This in evolutionary terms is odd. It’s odd in part because the panda has a short gut typical of carnivores. And it still possesses many of the genes associated with a carnivorous lifestyle. This is largely due to belonging to the bear family Ursidae. This is a group of animals … Read More

Theresa Cole; Jonathan Waters, and Kieren Mitchell, University of Adelaide Ever since Charles Darwin’s voyage to the Galapagos, biologists have been trying to figure out what determines the number of species that exist at any point in time. Our research, published this week, provides an answer to this question, at least when it comes to … Read More

Every so often there’s a new story claiming that a study has overturned our understanding of human evolution. (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 Sagan once said, extraordinary claims require extraordinary evidence – something that’s lacking in this particular … Read More

This is this idea that we either do this or something that we love dies – what might be referred to as ‘conservation at the barrel of a gun’. Here’s another collection of quotes from the feedback to Kim Hill again – the last one most notably being from one of New Zealand’s foremost conservation biologists: ‘By accepting many introduced … Read More

By the end of the school year, Year 13 students preparing for Schol Bio should have a pretty good grasp of the concepts and 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 before. I experienced that “what the … Read More

I 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 century onwards, plant medicines … Read More

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. At these days we usually … Read More

There are a number of things about my physical appearance I’m not 100% happy with. I’m pale, covered in freckles and I burn like a crisp on the odd sunny day. But perhaps worst of all is the fact that my eyebrows are virtually non-existent. Unless I carefully pencil them in each morning, my friends and coworkers struggle to ascertain … Read More

Patrick Randolph-Quinney, University of Central Lancashire and Anthony Sinclair, University of Liverpool This article was originally published on The Conversation. Read the original article. Just 20 years ago, many archaeologists believed there was a “human revolution” 40,000-50,000 years ago during which modern behaviours such as symbolism, innovation and art suddenly arose. This was thought … Read More
