First genetic evidence of long-lived African presence within Britain

Research has identified the first genetic evidence of Africans having lived among 'indigenous' British people for centuries. 24/01/07

Creating variation

Evolutionary change by natural selection (or genetic drift) requires variation in DNA. Where does this variation come from? 15/01/07

Letters begin

Is DNA (or RNA) sequence the only way information can be encoded and passed on from generation to generation? No. 15/01/07

Close cousins

Chimps are our closest relatives. Genome sequence comparisons are beginning to identify the key genes that distinguish us from them. 15/01/07

Religious following: The Y chromosome in India

Research has revealed that the spread of Islam in southern India was down more to culture than to genes. 01/12/06

Are humans still evolving?

We may have removed many selective pressures, but humans probably are still evolving. 29/09/06

100 000-year-old DNA sequence allows new look at Neandertal's genetic diversity

By recovering sequencing-intact DNA from an especially ancient Neandertal specimen, researchers have found evidence suggesting that the genetic diversity among Neandertals was higher than previously thought. 07/06/06

Most human-chimp differences due to gene regulation

The vast differences between humans and chimpanzees are due more to changes in gene regulation than differences in individual genes themselves, researchers argue. 09/03/06

Manchu Y chromosomes

An unusually frequent lineage of Y chromosomes in northern China and Mongolia has been linked to the Manchu conquest of China and the Qing dynasty. 12/01/06

'Perception' gene tracked humanity's evolution

A gene thought to influence perception and susceptibility to drug dependence is expressed more readily in humans than in other primates, a difference that may coincide with the evolution of our species. 15/11/05

Is size everything? Controlling human brain size

Human genetics, genome sequencing projects and cell biology are providing fascinating insights into the origins of our most important organ - the brain. 04/10/05

A series of fortunate events

Scientists are analysing genetic differences between humans and chimpanzees to shed light on the evolution of the human brain. 01/10/05

Mitochondrial DNA provides a link between Polynesians and indigenous Taiwanese

Mitochondrial DNA from nine Taiwanese tribes reveals a genetic link between aboriginal Taiwanese and Polynesian populations, to the exclusion of mainland Asians. 05/07/05
