The central role of humans in the Quaternary megafaunal extinctions in South America have been little considered by archaeologists. Based on temporal and spatial distributions of megafauna and Fishtail spear points, we propose that humans were the main (not the unique) factor driving the collapse.
We know that there are a great many species at risk of extinction, and it is easy to feel overwhelmed by the scale of action needed to conserve them. Where do we start tackling the pressures that are threatening these species, and encourage as many sectors as possible to act?
The following two fields have barely interacted before: artificial intelligence and molecular evolution. To demonstrate proof of concept, we established a machine-learning-based framework that substantially boosts tree-search algorithms, without compromising accuracy!
A precise timeframe for human evolution is fundamental to contextualise key events that occurred during the evolution of our lineage. Our new phylogenetic study dates specific speciation events and provides important insights into body mass and encephalization trends in human evolution.
In many coastal seas nutrient pollution caused severe oxygen depletion. We have therefore carried out future projections of one of them, the Baltic Sea, and examined the questions of when and where the first signs of improvement will emerge if the anthropogenic nutrient loads are further reduced.
By Andreas Lange, Prajal H. Patel and Geoffrey D. Findlay. In a collaboration that spanned three continents, we analysed the structure, function, and evolutionary history of a Drosophila protein that emerged from previously non-coding DNA and has since become essential for male fertility.
Register to Nature Portfolio Ecology & Evolution Community
The Nature Portfolio Ecology & Evolution Community provides a forum for the sharing and discussion of news and opinion in ecology and evolutionary biology. Through posts, discussion, image and video content, the community space can be used by members to communicate with each other, and with editors, about topics ranging from the fundamental science itself through to policy, society and the day to day life of the research community. It is also a place to learn more about the activities of Nature Research ecology and evolutionary biology editors and the policies and practices of our journals.
