Scientists report earlier date of shift in human ancestors' diet
2015-09-15 12:00:00| LifeSciencesWorld
[NEWS] Millions of years ago, our primate ancestors turned from trees and shrubs to search for food on the ground. In human evolution, that has made all the difference. The shift toward a grass-based diet marked a significant step toward the diverse eating habits that became a key human characteristic, and would have made these early humans more mobile and adaptable to their environment. New evidence just published by a research team led by a Johns Hopkins University …

Two-faced fish clue that our ancestors 'weren't shark-like'
2015-01-12 13:00:00| LifeSciencesWorld
[NEWS] An investigation of a 415 million year-old fish skull strongly suggests that the last common ancestor of all jawed vertebrates, including humans, was not very shark-like. It adds further weight to the growing idea that sharks are not 'primitive'. The fossil skull's external features meant it had always been thought to belong to the bony fishes (osteichthyans), a group which includes familiar fishes such as cod and tuna as well as all land-dwelling creatures wit…

2014-08-20 22:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: About 10 million years into the current Cenozoic Era, or roughly 56 million years ago, during a climate that was hot and wet, two groups of mammals moved from land to water. These were the cetaceans, which include whales, dolphins and porpoises, and the sirenians, with its sea cows, manatees and dugongs. Over time, their bodies began to adapt to their new environment. They lost their hind limbs, and their forelimbs began to resemble flippers. Their nostrils moved higher on their skulls. The cetaceans...
