Something for the weekend

I briefly mentioned some of the work of University of Manchester researchers Robin Baker and Mark Bellis. Their work on sperm competition in humans has attracted quite a number of popular articles.
Here's one from New Scientist: The subtle side of sex and one from the somewhat dubiously entitled seductionlabs.org: Sperm competition and the Kamikaze Sperm Hypothesis.

Both are well written and interesting articles with the latter article from 2007 being a little more critical of the kamikaze sperm hypothesis in humans than the earlier 1993 article.
