Tectonics in the tropics trigger Earth's ice ages

Over the last 540 million years, the Earth has weathered three major ice ages -- periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps. Now scientists have identified the likely trigger for these ice ages.


Diet-induced changes favor innovation in speech sounds

Diet-induced changes in the human bite resulted in new sounds such as 'f' in languages all over the world, a study by an international team led by researchers has shown. The findings contradict the theory that the range of human sounds has remained fixed throughout human history.


Unique diversity of the genetic history of the Iberian Peninsula revealed by dual studies



Posted: 14 Mar 2019 12:15 PM PDT


Researchers have analyzed ancient DNA from almost 300 individuals from the Iberian Peninsula, spanning more than 12,000 years. The first study looked at hunter-gatherers and early farmers living in Iberia between 13,000 and 6,000 years ago. The second looked at individuals from the region over the last 8000 years. Together, the two papers greatly increase our knowledge about the population history of this unique region.
