Proceedings of the National Academy of Sciences “Responses to pup vocalizations in subordinate naked mole-rats are induced by estradiol ingested through coprophagy of queen’s feces” Okay, we all knew that naked mole rats are weird. The inbreeding, the eusociality in a mammal, and… well, the look. But this is a new wrinkle. Apparently mom is sending Read More
A Minor Post, Behavior, Kin SelectionScience News “When this beetle mom disappears, her children become stronger and nicer” There are so many cool aspects to this study! First, it is amazing that lab evolution can produce this dramatic a change in both anatomy and behavior. These results are kind of like what we observe in artificial selection scenarios: there’s a lot Read More
A Minor Post, Behavior, Behavioral Ecology, Competition, Cooperation, Kin Selection, ParentingIt was a great honor to speak on this past Monday, March 7th, 2016 as part of Columbia University’s Population Biology seminar series. I gave a talk entitled “Breeders, Propagators, & Creators: Culture, Biology, and the Future of Human Evolution” to a small group of biology faculty and students from a nice diversity of different Read More

Biological parenting (what I call “breeding”… why to be explained) is a Read More

Here, the diversity of a soil bacterium (Myxococcus xanthus) is shown to be potentially explained by positive frequency-dependent selection, the Read More
A Minor Post, Articles, Competition, Cooperation, Ecological Modeling, Evolutionary Modeling, Kin Selection, Microbial Ecology, Soil EcologyProponents of kin selection as the most parsimonious explanation of how cooperation evolves face a problem when it comes to humans: counter to the predictions of kin selection theory, humans aim a fair amount of altruism at non-kin. While we do not aim our helping behaviors solely at our relatives, we also do not randomly Read More
A Major Post, Altruism, Articles, Behavior, Cooperation, Genetics, Group Selection, Human Evolution, Kin Selection, Psychology, Radio & Podcasts, Reciprocity, Social Networks, SociologyI am excited to report that my review of Origins of Altruism and Cooperation was just published in the Quarterly Review of Biology. Although it requires some work to get through, this collection presents a really important counter-narrative to the prevailing attitude in evolutionary biology that altruism is simply self-interest in disguise. The book uses Read More

In other words, we are not strictly “ethnocentric” in our cooperation: we are willing to cooperate with those not directly identified as our “in group”. This modeling Read More

There is valuable information here on why lions are social (unlike other large cats), why lions must cooperate, Read More
