Neandertals’ genetic legacy extends into africa - BioBlog

Alison Campbell Feb 03, 2020

For the last few years it’s been pretty much received wisdom that African populations shared only a tiny proportion of their genes, if any, with Neanderthals. In contrast, other non-African sapiens populations had a small but significant admixture of Neanderthal genes. The underlying reason for this, it’s been assumed, is that Homo sapiens and neandertalensis only bred with each other in Europe … Read More

The discovery of a Denisovan jaw bone and what it can tell us - From Past to Present

Michael Knapp May 09, 2019

Last week the discovery of a lower jaw bone of a Denisovan hit the headlines all over the world. Denisovans are a now-extinct species of humans that were closely related to us as well as to Neanderthals. To an outside observer, the excitement of researchers about this find might have appeared a bit over the top. After all, Denisovans have … Read More

How palaeolithic humans shaped the modern genome - News

Jean Balchin Jan 31, 2018

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

Human evolution – how do we accommodate new discoveries in our teaching? - BioBlog

Alison Campbell Jul 31, 2017

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

When did humans first leave Africa? - News

John Kerr Sep 22, 2016

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

Does Vegetarianism cause a mutation that leads to cancer? - Chthonic Wildlife Ramblings

Brendan Moyle Apr 01, 2016

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
