Homo floresiensis
2014-08-05 06:24:34

redOrbit Staff & Wire Reports - Your Universe Online Skeletal remains recovered from the Indonesian island of Flores over a decade ago are not a new species of “hobbit” sized human, but an ancient Homo sapien showing signs of abnormal development consistent with Down syndrome, an international team of researchers claim in a new Proceedings of the National Academy of Sciences study. According to NBC News, the 15,000-year-old fossil identified as LB1 had previously been determined...

Long-Term Climate Factors Led Early Humans To Patchwork Evolution
2014-07-04 11:14:48

Brett Smith for redOrbit.com - Your Universe Online In the past, scientists concluded many of man’s defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately. Based on analyses of fossil evidence, the study researchers said the shrinking of forests and expansion of savannas in East Africa led to walking upright, which freed our...

Killing Name Of An Extinct Sirenian Species
2014-04-03 12:34:02

Pensoft Publishers Sirenians, or sea cows, are a particular group of mammals that superficially resembles whales in having, amongst other features, a streamlined-body and horizontal tail fluke. Though belonging to the so-called marine mammals, such as whales and seals, sea cows are members of a group having a single origin that includes their closest living relatives, the proboscideans (or elephants in the broader sense). Today, sirenians are known by only four species, but their...

Seal Evolution Discovery And Sexual Dimorphism
2014-02-20 08:20:42

April Flowers for redOrbit.com - Your Universe Online Pinning down the answer to a widely-asked question is one of the most exciting things a researcher can do. For Thomas Cullen, who completed the research as part of his Master's degree at Carleton University, this experience came early in his career. Cullen, working with Canadian Museum of Nature paleontologist Dr. Natalia Rybczynski, made a ground-breaking discovery about pinnipeds — the suborder that makes up seals, sea lions, and...

New Fish Fossil Reveals How Fins May Have Become Hind Limbs
2014-01-14 06:11:22

[ Watch the video: Tiktaalik roseae fossils reveal evolution of hind limbs ] April Flowers for redOrbit.com - Your Universe Online The evolution of hind legs actually began as enhanced hind fins, according to the newly discovered, well-preserved pelvis and a partial pelvic fin from Tiktaalik roseae—a 375 million-year old transitional species between fish and the first legged animals. The findings, published in Proceedings of the National Academy of Sciences (PNAS), challenge the...

Humanlike Features Discovered In 4.4M-Year-Old Ardipithecus Skull
2014-01-07 06:54:22

April Flowers for redOrbit.com - Your Universe Online The 4.4-million-year-old African species Ardipithecus ramidus, or "Ardi," is the focus of one of the most hotly debated issues in current human origins research. Scientists want to know how Ardi, an unusual primate, is related to the human lineage. The study, published in the online edition of Proceedings of the National Academy of Sciences (PNAS), shows that although Ardi possessed a tiny brain and a grasping big toe for climbing...

Scientists Discover 4M-Year-Old Horse Fossil In Ethiopia
2013-12-12 13:58:55

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a new species of a small horse that lived 4.4 million years ago in Ethiopia. The Eurygnathohippus woldegabrieli fossils were found in the Gona area of the Afar region in 2001. The ancient horse was among a diverse array of animals that lived in the same areas as the ancient human ancestor Ardipithecus ramidus, or Ardi. The ancient horse species was about the size of a small zebra and had three-toed hooves....

Turtles Began Living in Shells Earlier Than Previously Thought
2013-05-30 16:35:52

Peter Suciu for redOrbit.com — Your Universe Online While there are several species that have shells, the turtle is the only animal to form such a shell on the outside of its body through a fusion of modified ribs, vertebrae and shoulder girdle bone. This makes the turtle´s shell a unique modification, one that has fascinated and confounded biologists for more than two centuries. How and when it originated has remained mostly conjecture. However, a team of researchers led...

Chinese Study Provides Evidence That Early Birds Had Four Wings Instead Of Two
2013-03-15 08:31:22

Lawrence LeBlond for redOrbit.com - Your Universe Online When you inspect the legs of most birds you will find everything from the knee down is scaly rather than feathery. There is an exception to this rule however. Some birds of prey, such as eagles, have more feathering below the knee extending down to the feet. As for those with scaly legs, it is a remnant of their ancestry, when birds evolved from small two-legged dinosaurs millions of years ago. For the most part, experts...

New fossil reveals history of last-living marine mammals to eat only aquatic plants A new fossil discovered in Tunisia represents the oldest known ancestor of modern-day sea cows, supporting the African origins of these marine mammals. The find is described in research published January 16 in the open access journal PLOS ONE by Julien Benoit and colleagues from the University of Science and Technology in Montpellier, France. Some fossils of sea cow ancestors have been found in Jamaica,...

Australopithecus garhi
2013-11-29 11:38:51

Australopithecus garhi is a gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw ad Tim White, an American paleontologist. The remains are believed to be a human ancestor species and most likely the direct ancestor to the human genus Homo. Tim White was the scientist to find the first of the key A. garhi fossils in 1996 within the Bouri Formation found in the Middle Awash of Ethiopia’s Afar Depression....
