China shifts a failed cultural policy designed to stabilize population

Posted 29 Oct 2015 / 1

The New York Times “China to End One-Child Policy, Allowing Families Two Children” This was a long time coming (see Mara’s Hvistendahl‘s great 2010 piece in Science Magazine for perspective), but the Chinese Communist Party has finally decided to replace its “one child policy” with a “two child policy”. From an evolutionary perspective, there is Read More

Major masts made by multiplicative modification

Posted 22 Oct 2015 / 0

Ecology Letters “Extended flowering intervals of bamboos evolved by discrete multiplication” This is a great example of how theory can be used to explain patterns in nature by matching patterns in nature. Masting is a group-level evolved phenomenon: producing seeds in abundance during a single year where every other plant of your species is doing Read More

Group phenotypic composition: implications for individuals and their groups

Posted 22 Oct 2015 / 0

Trends in Ecology & Evolution “From Individuals to Groups and Back: The Evolutionary Implications of Group Phenotypic Composition” Man, I wish that this article was written in a more accessible manner, because what it presents is important. There is a critical feedback between how the composition of groups affects individuals and how individuals affect the Read More

David Sloan Wilson on how Jeff Bezos don’t know squat about chickens (or evolution!)

Posted 16 Oct 2015 / 1

Evonomics “Jeff Bezos got Darwinism all Wrong!” This is an interesting analysis of the Bezos way of doing business, which represents an oft-lauded bastardization of Darwinian theory. What I like about Wilson’s brief analysis is that he focuses back on the unit of selection that matters for a business: the corporation. Unless you naively believe Read More

Malcolm Gladwell on the social contagion of mass shootings

Posted 13 Oct 2015 / 0

National Public Radio Morning Edition “How Riots May Help Us Understand School Shooters” This is a great example of how understanding our cultural evolution, and how we have evolved to live culturally, could allow us to solve a social problem. We need to figure out a way to break the cultural continuum from one mass Read More

Like-with-like assortment plus exponential fitness increases cooperation, even under weak selection

Posted 06 Oct 2015 / 0

arXiv “Assortment and the evolution of cooperation in a Moran process with exponential fitness” I am still struggling to understand when it would be appropriate to assume an exponential (rather than linear) fitness function. It is wonderful that these modelers are mapping out all these different conditions under which cooperation evolves, but how to select Read More

Should we compromise with nations that hunt whales?

Posted 06 Oct 2015 / 0

Frontiers in Ecology and Evolution “A deal with Japan on whaling?” Having been a fan of Whale Wars for awhile, and being predisposed to thinking that we ought to protect large, social, cooperative, cognitively-advanced animals, it is a bit hard for me to accept legal whaling of any kind. But as this article points out Read More

The often-large difference between “breeding” and “parenting”

Posted 02 Oct 2015 / 0

WNYC The Leonard Lopate Show “Options Grow For Starting a Non-Traditional Family” As I continue to work on my popular science book with the working title Breeders, Propagators, & Creators, I have been thinking a lot about what it means to be a parent. Biological parenting (what I call “breeding”… why to be explained) is a Read More

New report on drug resistance highlights the tragedy of our antibiotics commons

Posted 02 Oct 2015 / 0

National Geographic Germination blog “Antibiotic Resistance Getting Worse Globally, But Fixes Could Be Simple” Antibiotic resistance is an interesting problem because it highlights how individual decisions drive international-scale dynamics and then come right back to impact individuals. Unlike other big international tragedies of the commons such as climate change or fisheries collapse, the effects of Read More
