Many mammals came perilously close to extinction when a massive asteroid hit the earth 66 million years ago, says a study, adding that if a few lucky species did not make it through then mammals may have gone the way of the dinosaurs.
The most ambitious genetic study ever, involving over 200 scientists from across the world and 23 research papers, undertaken on bird evolution has found that almost all modern birds diversified after the dinosaurs became extinct 66 million years ago.
Researchers at the University of Maryland Center for Environmental Science and the University of Vermont in the US have developed a new tool to overcome a major challenge of predicting how organisms may respond to climate change.
In a disturbing trend, scientists have reported that species are becoming extinct as much as 1,000 times more frequently - 10 times worse than the previous estimates - owing to human population growth and increasing per capita consumption.
New Antarctica atlas, which is first of this magnitude since the publication of the Antactic Map Folio Series 45 years ago, has helped marine biologists from across the world in finding thousands of new species in the ocean.
