When it comes to considering sex and gender, don’t forget sex determination

Posted 22 Oct 2018 / 0

Scientific American “Beyond XX and XY: The Extraordinary Complexity of Sex Determination” I teach about sex and gender in a lot of my courses. For some courses, such as Evolution or The Evolution of Sex, these are basic concepts that need to be established in order to study reproductive behaviors. For other courses, such as Breeders, Propagators, & Read More

Personalized DNA tests likely to provide further evidence of human inter-connectedness

Posted 06 Jan 2016 / 0

Great NPR piece here on how new technologies in personalized DNA testing have the potential to broadly expand our understanding of human relatedness. I am particularly interested in the idea that these tests further reinforce previous research showing just how much of our gene pool is shared globally rather than locally. While these tests are Read More

To be an effective critical theorist of science, it helps to understand science

The Chronicle of Higher Education “An Unevolved View of Gender Evolution” Although I am sympathetic to a number of the critiques of traditional sexual selection theory, I have to agree with the overall thrust of this book review: if you are going to shine a critical light on scientific understandings of sex differences in humans, Read More

The problem with same sex attraction “for the good of the species”

Posted 16 Nov 2015 / 0

arXiv “Toy model for the adaptive origins of the sexual orientation continuum” This is an interesting idea that definitely bears further exploration, but by my reading of the math, the tradeoff here (what’s good for the species in having trait diversity versus what’s good for an individual in achieving reproductive success) is expressed purely in Read More

Fascinating and clever study of how personal contact norms vary by relationship

Posted 10 Nov 2015 / 0

Image from PNAS Proceedings of the National Academy of Sciences “Topography of social touching depends on emotional bonds between humans” (Suvilehto et al. 2015) This is a really clever study in that it aggregates a lot of data that is collected rather efficiently from a lot of participants. This makes the results robust for this Read More

That beard and deep voice may be to put him in his place, not attract her

Posted 09 Nov 2015 / 0

There have been a lot of evolutionary psychology experiments that have tried to define both female and male attractiveness to the opposite sex, an indirect way to get at the nature of sexual selection in humans. A new study published in Behavioral Ecology reminds us that sexual selection is not the only process that has Read More

Isabella Rossellini’s Green Porno

Posted 21 Jul 2013 / 0

I have been preparing for next semester’s Evolution of Sex course by looking for new media that might help my students. I just spent a few enjoyable hours checking out Isabella Rossellini’s Green Porno series, produced by the Sundance Channel. I have been aware of Rossellini’s rather interesting foray into the world of animal sex and reproduction for awhile Read More
