Research from the University of Cambridge has revealed that, among schooling fish, groups can have different collective personalities, with some shoals sticking closer together, being better coordinated, and showing clearer leadership than others.
Ancient DNA analyses show that – unlike elsewhere in Europe – farmers from the Near East did not overtake hunter-gatherer populations in the Baltic. The findings also suggest that the Balto-Slavic branch of the Indo-European language family originated in the Steppe grasslands of the East.
In contrast to Western Europeans, new research finds contemporary East Asians are genetically much closer to the ancient hunter-gatherers that lived in the same region eight thousand years previously.
Populations of hunter-gatherers weathered Ice Age in apparent isolation in Caucasus mountain region for millennia, later mixing with other ancestral populations, from which emerged the Yamnaya culture that would bring this Caucasus hunter-gatherer lineage to Western Europe.
DNA from 4,500-year-old Ethiopian skull reveals a large migratory wave of West Eurasians into the Horn of Africa around 3,000 years ago had a genetic impact on modern populations across East Africa.
Researchers say that the first study to attempt to gauge global visitation figures for protected areas reveals nature-based tourism has an economic value of hundreds of billions of dollars annually, and call for much greater investment in the conservation of protected areas in line with the values they sustain – both economically and ecologically.
Research reveals that sticklebacks with bolder personalities are not only better leaders but also less sociable than more timid fish. The behaviour of these bolder fish shapes the dynamics of the group.
Ancient DNA shows earliest European genomes weathered the ice age, and shines new light on Neanderthal interbreeding and a mystery human lineage06 Nov 2014
A genome taken from a 36,000 year old skeleton reveals an early divergence of Eurasians once they had left Africa, and allows scientists to better assess the point at which ‘admixture’ - or interbreeding - between Eurasians and Neanderthals occurred. The latest research also points to a previously unknown population lineage as old as the first population separations since humans dispersed out of Africa.
Latest research shows that coral trout can now join chimpanzees as the only non-human species that can choose the right situation and the right partner to get the best result when collaboratively working.
The genome of a child who died some 12,600 years ago in Montana – the oldest known human remains from North America – has been sequenced for the first time.
