Karakostis et al. add muscle to the story of hand evolution with their analysis of torque at the thumb …
Numbers indicate Brodmann’s areas BC: Brodmann’s cap LA: lambdoid suture In humans, evolutionary expansion of the inferior prefrontal cortex (IPF) resulted in a shift of the pci toward the posterior side of CO (red arrowheads). Concomitant expansion of the parietal bone resulted in anterior shift (blue arrowheads) of the apical portion of CO. In humans, …

Feb. 19th Science: “A global environmental crisis 42,000 years ago” Do terrestrial geomagnetic field reversals have an effect on Earth’s climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a …
