Origins of cumulative culture in human evolution      (via sciencedaily.com)     Original source 

Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.

Direct evidence found for dairy consumption in the Pyrenees in the earliest stages of the Neolithic      (via sciencedaily.com)     Original source 

A study on the remains of the Chaves and Puyascada caves, both located in the province of Huesca, Spain, yields the first direct proof of the consumption and processing of dairy products in the Pyrenees already at the start of the Neolithic period, approximately 7,500 years ago, as well as the consumption of pig. The results lead to doubts about the belief that these products were first used much later in the Pyrenean mountain range.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

Ritual sacrifice at Chichén Itzá      (via sciencedaily.com)     Original source 

Rising to power in the wake of the Classic Maya collapse, Chichen Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh.

Scientists unlock secrets of how archaea, the third domain of life, makes energy      (via sciencedaily.com)     Original source 

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.

Shedding light on the origin of a genetic variant underlying fungal infections      (via sciencedaily.com)     Original source 

Variants in the CARD9 gene increase susceptibility to severe fungal infections. However, individuals in different parts of the world tend to carry specific CARD9 variants, making it complex to track the origin of these mutations. In a recent study, a research team conducted genetic analyses on Japanese, Korean, and Chinese patients, revealing that they all shared a variant of CARD9 stemming from a common ancestor from less than 4,000 years ago.
