The Attini tribe rely solely on the cultivation of Fungus Gardens for food. When an Attine Daughter Queen leaves her maternal home, she must carry within her mouth a Nucleus of Fungus to serve as the Starting Culture for her new Garden (Schultz and Brady 2008).... Read more »
We’ve long assumed that Africa is home to the widest genetic diversity in humans. After all, it’s our ancestral home and it only makes sense that as we spread throughout the world, the genetic variation for each culture and society eventually narrowed. This is why the recent headline about a 10 year study by a team of[...]...... Read more »

The region of the Middle East referred to as “Levant” includes modern day Israel, Palestine and Jordon, and there are few places on earth more intensely studied by archaeologists than the birthplace of monotheistic religion. In addition to yielding a vast record of human occupation, culture and war, the archaeological sites within this region also document the decimation of several mammalian species. A couple of days ago (April 29), several Israeli scientists published an article in PLoS One........ Read more »

Most scientific publications today are accessed online. That is why Johan Bollen and colleagues used nearly 1 billion user interactions recorded by the scholarly web portals of some of the most significant publishers, aggregators and institutional consortia to create a high-resolution map of science in an article published on PLoS One. A first-order Markov chain was extracted from the sequence of user interactions recorded and the model was visualized as shown below to describe the relationships........ Read more »

Technorati Tags: venison,lead,hunting So, I read a very interesting paper this week, and indeed, you must also know about it. It really has nothing to do with the premise of this blog, but forget all that. It was initially an interesting paper, because it was about residue lead bullet fragments in hunted deer, i.e. venison. I was completely unaware that so much lead is left in a carcass post cleaning and processing. Two feeds of meat, 24 hours apart, will raise blood lead concentration by a fac........ Read more »

Ants never cease to amaze me. Published in Nature in 2006 Nigel R. Franks and Tom Richardson at the University of Bristol displayed ants of the species Temnothorax albipennis teaching one another. The ants use a technique called tandem running, which utilizes bidirectional feedback between teacher and pupil, to lead a naive ant from the nest to food.... Read more »
Recently there have been some interesting articles trying to better understand what is happening in Bronze Age Thailand, and by extension, Bronze Age Southeast Asia. I figured writing a blog post about these articles would be a good way to start thinking through some of this data. It’s becoming more and more obvious that the [...]... Read more »

A new study in the journal PLoS One, by Cristina Gomes and Christophe Boesch of the Max Planck Institute for Evolutionary Anthropology, finally answered a question that has intrigued primatologists for nearly two decades. Do female chimpanzees preferentially mate with males who share their hunting gains with them? This hypothesis was first suggested in 1994 by Craig Stanford and Jane Goodall when they found that the best predictor for whether males would engage in a hunt or not was the presence ........

Was doing one of my weekly Scopus searches for new articles and came across the following review (PDF, 4 pages) on biochar, and it seems rather timely given that I've highlighted this topic recently. The title of this blog is taken from the title of the article, and it talks about the terra preta soils of the Amazon.The soils are proof of concept that burying biochar (biomass-derived charcoal) in the soils will both: increase soil productivity/fertility; and trap carbon for long periods of time ........

Although it was literally a dark and stormy night, such weather conditions were but a novelty to the speaker – a scientist whom had spent the majority of his life scanning barren rocks and desiccated landscapes for fragments of fossil bone beneath the unrelenting and scorching sun of an East African desert. Yet, I can’t help but think that some level of instinctual fear naggingly tickled at his stomach as he approached the waiting crowd…

Just a quick follow-up on my earlier post. Foroni & Semin (in press, Psychological Science) do what I hoped somebody did: examining the bodily grounding of non-ideophonic vocabulary related to emotional states. Theirs is not an imaging study like Osaka & Osaka 2005, but a study of motor resonance in facial muscles. The terms tested are action verbs (to smile; to frown) and adjectives for the corresponding emotional states (without overt facial configurational semantics), e.g. 'happy; angry&........ Read more »
