Shame on You, Shame on Me: Shame as an Evolutionary Adaptation
by Jalees Rehman in The Next Regeneration
Can shame be good for you? We often think of shame as a shackling emotion which thwarts our individuality and creativity. A sense of shame could prevent us from choosing a partner we truly love, speaking out against societal traditions which propagate injustice or pursuing a profession that is deemed unworthy by our peers. But if shame is so detrimental, why did we evolve with this emotion? A team of researchers led by Daniel Sznycer from the Center for Evolutionary Psychology at the University ........ Read more »

Hadza hunter-gatherers, social networks, and models of cooperation
by Artem Kaznatcheev in Evolutionary Games Group
At the heart of the Great Lakes region of East Africa is Tanzania — a republic comprised of 30 mikoa, or provinces. Its border is marked off by the giant lakes Victoria, Tanganyika, and Malawi. But the lake that interests me the most is an internal one: 200 km from the border with Kenya at […]... Read more »

Lomekwi 3 and the Invention of Technology
by Andrew White in AndyWhiteAnthropology
Last week I wrote a post about the 3.3-million-year-old pre-Oldowan stone tool assemblage reported from the Lomekwi 3 (LOM3) site in Kenya by Harmand et al. (2015). As I was writing that, I remembered a 2004 paper by Sophie A. de Beaune titled "The Invention of Technology" (Current Anthropology 45(2):139-162) that I had read in grad school. That paper takes a long-term view of the evolution of technology focusing on the development and proliferation of different kinds of percussion.&........ Read more »

What's a "Species"?
by Andrew White in AndyWhiteAnthropology
The naming of a new species of hominid -- Australopithecus deyiremeda -- made a lot of news this week. The purpose of this post is not to worry over the details of the fossils that were used to construct this new taxon, but to ask for some clarification about what is actually meant by the term "species" as paleoanthropologists use it. I'm going to tell you what I think it means, then I'm going to complain about it a little bit, then I'm going to ask you to tell me what you thin........ Read more »

Human Evolution and the Stone Tool "Problem"
by Andrew White in AndyWhiteAnthropology
The recent announcement of the discovery in stone tools in Kenya dating to 3.3 million years ago (MYA) has been greeted with a lot of fanfare. I first heard the story at some point earlier in the academic year, and I know there was a lot of buzz about it at the SAAs and Paleoanthropology meetings in San Francisco in April. The publication of a formal paper in Nature last week (“3.3-Million-Year-Old Stone [...] ... Read more »

The Dependency Ratio in Human Evolution
by Andrew White in AndyWhiteAnthropology
As far as I know, humans are unique among animals in having an extended period between weaning and being able to subsist on their own. We call this “childhood.” The long period of post-weaning dependence provides our large brains with a lot of time to mature. It also requires a lot of parental investment (in terms of time, energy, calories, etc.) and means that we would have to wait a long time between offspring if each one had to independent before the mother could have an [...] ...

Missing link in the evolution of complex cells discovered
by Perikis Livas in Chilon
In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes.

Robot Discovers Two New Neighbors
by Perikis Livas in Chilon
Maunakea, Hawaii – A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15, and 24 days. The paper is being published in the Astrophysical Journal....

Major Advance in Artificial Photosynthesis
by Perikis Livas in Chilon
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels....
