Lost elms of Kent

Mature elm trees in the English landscape are something I and many other have never seen. Dutch Elm Disease killed them all in the 1960s. Only the older generation can remember what we have lost. Browsing through some local photos from the 1930s this weekend, my eyes were opened to the size and grace of… Continue reading Lost elms of Kent

How to lead a journal club

Getting together to discuss a published paper is a classic way of keeping on top of the literature and training students how to read it. During my postgraduate studies I went to a journal club every week organised by my PhD supervisor. It was here that I learned how to read a scientific paper, and… Continue reading How to lead a journal club

How similar are human and chimpanzee genomes?

I recently participated in a discussion on the Biologos forum on the degree of similarity between the human and chimpanzee genomes. I was asked for my current view on this issue by Dennis Venema, who had found a old quote online from a newspaper article that I had written in 2008 on this issue. In… Continue reading How similar are human and chimpanzee genomes?

Adam and Eve: lessons learned

This blog was first posted at Nature Ecology & Evolution Community on 14 April 2018 Preliminary conclusions about the possibility of a short, sharp human bottleneck A few months ago I asked this community if modern genome science had tested an “Adam and Eve” hypothesis that the human lineage has passed through short, sharp bottleneck… Continue reading Adam and Eve: lessons learned

Coalescence at bottlenecks

This is Part 1 of my response to Dr Dennis Venema’s second Biologos Blog “Adam, Eve and Population Genetics: A Reply to Dr. Richard Buggs (Part 2)”. Dr Venema was responding to my blog at Nature Ecology and Evolution Community about his book Adam and the Genome. Since Dr Venema’s Part 1 blog responding to… Continue reading Coalescence at bottlenecks

Response to Dennis Venema’s Blog “Adam, Eve and Population Genetics: A Reply to Dr. Richard Buggs (Part 1)”

This is my response to Dennis Venema’s Biologos blog that he posted after I published my email and blog at Nature Ecology and Evolution Community about his book Adam and the Genome. This text is also placed as a comment under Dr Venema’s blog post on the Biologos blog page. Dear Dennis, I am glad… Continue reading Response to Dennis Venema’s Blog “Adam, Eve and Population Genetics: A Reply to Dr. Richard Buggs (Part 1)”

Marcus Wallenberg Prize 2017

MWP, Marcus Wallenberg-priset

Last week in Stockholm the forest geneticist Prof. Ron Sederoff was awarded the Marcus Wallenberg Prize. Informally known as the “Nobel Prize for Forestry”, this two million Swedish Krona award is presented by the King of Sweden each year. It is the first time for a decade that the prize has gone to a biologist.… Continue reading Marcus Wallenberg Prize 2017

Adam and Eve: a tested hypothesis?

Does genomic evidence make it scientifically impossible that the human lineage could have ever passed through a population bottleneck of just two individuals? This is a question I am asked semi-frequently by religious friends. With my current understanding of the genetic evidence, I can’t state categorically that it’s impossible. In this view, I find I differ… Continue reading Adam and Eve: a tested hypothesis?
