In what could prove to be a landmark discovery, a leading paleontologist said scientists have dug up the 47 million-year-old fossil of an ancient primate whose features suggest it could be the common ancestor of all later monkeys, apes and humans.

Anthropologists have long believed that humans evolved from ancient ape-like ancestors. Some 50 million years ago, two ape-like groups walked the Earth. One is known as the tarsidae, a precursor of the tarsier, a tiny, large-eyed creature that lives in Asia. Another group is known as the adapidae, a precursor of today’s lemurs in Madagascar.

Based on previously limited fossil evidence, one big debate had been whether the tarsidae or adapidae group gave rise to monkeys, apes and humans. The latest discovery bolsters the less common position that our ancient ape-like ancestor was an adapid, the believed precursor of lemurs.

Philip Gingerich, president-elect of the Paleontological Society in the U.S., has co-written a paper that will detail next week the latest fossil discovery in Public Library of Science, a peer-reviewed, online journal. Continue reading ‘47 million year old fossil of an ancient primate discovered’

Protecting the Seas

 

Only one oil spill can cause enormous devastation on wildlife and habitats, but seas all over the world take in millions of gallons of oil every year. The long-term effect of such a disaster is the subject of much debate among scientists. Some argue that animals and birds are harmed many years after the event, while other people believe wildlife is more resilient. For example, according to research, otters and other animals are still suffering nearly 12 years after the Exxon Valdez oil spill in Alaska, which is considered one of the worst in terms of damage to the environment.
