Robot dog meet robot stick - Unsorted

Robert Hickson Jul 03, 2019

  Four years ago I wrote about getting too carried away with evolutionary metaphors for robots. But I can’t deny that we’re are seeing an increasing diversity of robotic forms and capabilities. The technological sophistication of high-end robotics, and the speed with which they are improving, is impressive. Check out SpotMini’s moves.   … Read More

Ardipithecus and bipedal walking - BioBlog

Alison Campbell Feb 25, 2019

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

Pandas and Bamboo: A recent dietary specialisation? - Chthonic Wildlife Ramblings

Brendan Moyle Feb 11, 2019

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

Human evolution and attention-grabbing headlines - BioBlog

Alison Campbell Jan 16, 2019

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

From Restoration to Reconciliation: Belief 9 – We have to do it - So Shoot Me

Jamie Steer Dec 22, 2018

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

A pivotal species? What’s that? - BioBlog

Alison Campbell Nov 20, 2018

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
