In my latest feature I'm exploring the recent discoveries of surprisingly large numbers of rare genetic variations in individual human genomes. Experts have attributed these to the rapid population expansion since the beginning of agriculture. There is still some debate re. whether or not the accumulation of such mutations poses a threat to the future health of our species.
The feature appears as part of a special review issue on Evolution and Human Health in today's issue of Current Biology:
Rapid population rise bad for our health? Current Biology, Volume 22, Issue 17, R702-R705, 11 September 2012 doi:10.1016/j.cub.2012.08.040
The other articles that are part of the special themed section are also on open access.
