As I have been working on my book-in-progress (Breeders, Propagators, & Creators), I have encountered a difficult-to-answer question of road-block proportions: how do we quantify cultural transmission? The focus of my book is the tradeoff humans face between making babies, spreading existing culture, and inventing new ideas. If such a tradeoff exists, we need to be able Read More

One of the ideas that I am exploring in my work-in-progress book Breeders, Propagators, & Creators is that human beings face a fundamental trade-off between three activities: Breeding: behaviors that lead to the production of offpsring (which might — but does not necessarily — include parenting); Propagating: behaviors that spread existing cultural ideas; and Creating: behaviors that introduce Read More

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

Last Friday (December 11th, 2015) I had the pleasure of speaking to students and faculty at Saint Francis College. I delivered a talk entitled “Highly-creative baby-breeding idea propagators: what human (re)productive choices mean for the future of our species” to an engaged and insightful audience; as this was the final week of classes, I really Read More

Next Friday, December 11th, at 3 pm I will be delivering a talk at St. Francis College entitled “Highly-creative baby-breeding idea propagators: what human (re)productive choices mean for the future of our species“. The talk is a synopsis of a large section of my book-in-progress Breeders, Propagators, & Creators: Culture, Biology, and the Future of Human Evolution. Read More

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

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

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

There’s a new paper out in the Proceedings of the National Academy of Sciences by David W. Lawson and colleagues that looks at whether the cultural practice of polygyny is disadvantageous. It’s a question that should be fascinating to anyone who is interested in sexual conflict or cultural evolution. At first glance, polygyny appears to be Read More

BBC Earth “Why some male bats have spines on their penises” In my Evolution of Sex class we talk a lot about sperm competition, so spiky penises are nothing new to me. But I was not aware that bats had spined penises of such diversity. And I find it really interesting that because bat behavior Read More
