Competitive Generosity Drives Charitable Donations

Fri, 17 Apr 2015 12:09:46 +0000

Unconditional generosity is a characteristic of humans on which we pride ourselves, and billions of dollars is donated to hundreds of thousands of charitable organisations every year. But look at it from an evolutionary perspective, and this trait seems difficult to explain. In some situations, giving may have evolved to advertise positive characteristics of the […]

Male Promiscuity Boosts Role of Chance in Sex Chromosome Evolution

Thu, 19 Mar 2015 15:02:31 +0000

Humans, like all mammals and birds, determine sex with chromosomes. Whether a fertilised egg develops into a male or female depends on what chromosomes it carries Scientists have long recognised that genes evolve a little differently on the sex chromosomes, and recent research in GEE suggests this may be due to differing patterns of inheritance […]

Sloths Move Slow, Evolve Fast

Wed, 11 Mar 2015 18:20:41 +0000

Sloths might be notorious for their leisurely pace of life, but research published last year shows they are no slow coaches when it comes to evolution. Sloths, as we know and love them, are small, slow-moving creatures found in the trees of tropical rainforests. But modern sloths are pretty odd compared to their extinct relatives. […]

Write About Research – A GEE Research Blog Competition

Tue, 03 Mar 2015 15:28:43 +0000

The GEE Research blog communicates UCL science with a wider, non-specialist audience, by providing short summaries of recent research in the department of UCL Genetics, Evolution and Environment. This provides an opportunity to engage with a broad audience, including other academics, students, members of the public, and even businesses and policy-makers. It is a great […]

LeCHE MEETING

14 May 2010

A new study led by UCL scientists (in GEE) has found that current genetic data cannot explain why vast swathes of the world can digest milk.

Study co-author Dr Yuval Itan (UCL Genetics, Evolution and Environment) explains more fully what this study reveals.

The ability to digest the milk sugar lactose – also known as lactase persistence – is a selectively advantageous and recent evolutionary genetic trait, which emerged about 7,500 years ago in Europe and probably later in other parts of the world. This means that, once weaned, people in most parts of the world (large parts of Africa, most of Asia, and Oceania) cannot digest milk for the rest of their life.

However, the study published in BMC Evolutionary Biology, shows that the four genetic mutations currently associated with the ability to digest milk cannot explain why many people in western and southern Africa, south eastern Europe, the Middle East, and southern and central Asia are able to digest milk. It also suggests that other genetic variants leading to the ability to digest milk exist, but have not yet been discovered.
