New research confirms that natural selection is acting on the current human population

to a western world context, he said.

Twin analysis

The Australian Twin Registry (ATR) is one of the largest twin databases in the world. It is managed by Professor Nick Martin, another author on the paper, and has taken 30 years to build up. It is normally used to study inherited diseases, but evolutionary biologist Dr Owens was the first to suggest that the data could be used to indicate changes in human evolutionary behaviour.

To calculate whether any of these attributes were genetically inherited, the team analysed lifestyle questionnaires previously gathered by the ATR. The register contains details for 30,000 twins. Of these, 2,710 pairs of identical and non-identical satisfied the criteria for inclusion in the teams research.

The data were then assessed using the classical twin method. This method scores traits on a scale that ranges from wholly genetic through to wholly environmental.

The researchers placed these scores into special structural models on a computer, which allowed a number of different influences to be compared within a rigorous statistical framework. The results revealed any correlations between life history traits and reproductive fitness, removing the effect of social and psychological factors.
