Past climate change pushed birds from the northern hemisphere to the tropics

Researchers have shown how millions of years of climate change affected the range and habitat of modern birds, suggesting that many groups of tropical birds may be relatively recent arrivals in their equatorial homes.

Species ‘hotspots’ created by immigrant influx or evolutionary speed depending on climate

New research reveals that biodiversity ‘hotspots’ in the tropics produced new species at faster rates over the last 25 million years, but those in temperate regions are instead full of migrant species that likely sought refuge from shifting and cooling climates.

Ancient DNA analysis unlocks secrets of Ice Age tribes in the Americas

Scientists have sequenced 15 ancient genomes spanning from Alaska to Patagonia and were able to track the movements of the first humans as they spread across the Americas at “astonishing” speed during the last Ice Age, and also how they interacted with each other in the following millennia.
