I've tried to embed my recent TED talk (mini) here, but PT's system seems to have some trouble with embedded vids. But whether or not the vid appears below, if you are interested in seeing me discuss some of the evidence for sperm competition in the human past in greater depth at the big TED event next year, please go to the original TED page here, and say so in the comments section there. If there are enough enthusiastic comments on their site, they're more likely to invite me to the main TED gig. Thanks.
