When we think about our ancestry, we think about our grandmothers and grandfathers – and, if we have photo albums nearby, or a family member interested in genealogy, we might know a bit more about our great-grandmothers, great-grandfathers, and so on. I remember traveling around Scotland a few years ago, and chancing upon a small churchyard. Every second gravestone, most … Read More

What follows is loosely based on a workshop I ran at this year’s Biolive/ChemEd secondary science teachers’ conference. (A most excellent conference, by the way – kudos to those organising & presenting.) I’ve added a bunch of hotlinked references. Back when I was in 7th form (or year 13 – i.e. a rather long time ago), the description of … Read More

Where did we come from and when did we leave there? These existential questions are at the heart of several human genetics studies published today in the leading journal Nature, all with links to New Zealand. Tracing our genetic roots The now widely accepted ‘Out of Africa’ hypothesis puts Africa as the origin of all modern humans. However, there is still debate … Read More

The short answer. No. Longer answer: Newspapers are fond of stories that breathlessly announce discoveries as revolutionary. Fossils never add anything to our knowledge incrementally. They will always rewrite the theory of evolution. Cancer is another popular target for revolutionary new treatments or causes. So it was with some skepticism I read that, quote, “Scientists have found vegetarianism can cause a … Read More

Peter K. Dearden Perspective is an important thing in understanding science. I, like everyone else on earth should, have an interest in the evolution of our species. I am struck by the conundrum that we seem very different from our nearest relatives, yet genetically we are very similar. I bet a lot of that is about perspective. It is easy … Read More

Ask anybody today what the fundamental requirements of life are, and they will tell you….food, shelter, lighting, warmth, their iphone… Ask anybody in prehistory what the fundamental requirements of life are, and they may tell you….food, shelter, lighting, warmth… And for most of this, until recently, that meant fire.

I'm giving a big talk next week - a departmental seminar. It's the first time I've had more than 15 minutes to talk about my research, so this talk will be a little more discursive that my usual. I study speciation, how new species come into being, a... Read More
