Evolution of Man

New research claims to have found traces of evidence that humans may indeed still be evolving. A study looked at the DNA of over 200,000 people living across both the United States and Britain, to see if they could tease out any changes in genetic variation in these populations over time. They report that their analysis of these genomes shows natural selection is weeding out gene variants most often associated with Alzheimer’s disease and heavy smoking. Jeff and Anthony discuss our continuing evolution as a species and what this could mean.
