Whales lost their teeth before evolving hair-like baleen in their mouths

Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen -- rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water.

Stone tools linked to ancient human ancestors in Arabia have surprisingly recent date

Beginning more than 1.5 million years ago, early humans made stone handaxes in a style known as the Acheulean - the longest lasting tool-making tradition in prehistory. New research has documented an Acheulean presence in the Arabian Peninsula dating to less than 190,000 years ago, revealing that the Arabian Acheulean ended just before or at the same time as the earliest Homo sapiens dispersals into the region. from All Top News -- ScienceDaily https://ift.tt/2E2TUvj

How the devil ray got its horns

If you ever find yourself staring down a manta ray, you'll probably notice two things right away: its massive fins and the two fleshy growths curling out of its head that give it the nickname 'devil ray.'

Quirky glacial behavior explained

In August 2012, the Jakobshavn Glacier was flowing and breaking off into the sea at record speeds, three times faster than in previous years. As the glacier flowed faster, it became thinner and more unstable and in a twist, a pileup of thick ice replenished the glacier's terminus, slowing it down again. New work explaining the fast-then-slow movement of Jakobshavn may help scientists better predict how tidewater glaciers contribute to sea level rise. from Top Environment News -- ScienceDaily https://ift.tt/2AAouIA
