What is the purpose of reproducing sexually, from a Darwinian perspective? A sexual organism has to discard half of his or her genetic material when forming an offspring, so surely it is more advantageous to clone oneself. Genes for cloning would be guaranteed a copy of themselves in the following generation for each offspring produced,Continue reading “The evolution of sexual reproduction”

The genetic architecture of facial variation

The following is a non-technical summary of our work on facial feature genetics together with some musings on future possibilities, with some genealogical ideas. It is reproduced here from the Lost Cousins newsletter for which I contributed it in 2017. Additional research has since been published by other groups, which I may comment on later. ————————————————————————————————— Most of us atContinue reading “The genetic architecture of facial variation”
