Geneticists and anthropologists previously suspected that ancient Africans domesticated cattle native to the African continent nearly 10,000 years ago. Now, a team of University of Missouri researchers has completed the genetic history of 134 cattle breeds from around the world. In the process of completing this history, they found that ancient domesticated African cattle originated in the "Fertile Crescent," a region that covered modern day Iraq, Jordan, Syria and Israel. In their study...

Did Inbreeding Drive Woolly Mammoths To Extinction?
2014-03-26 09:19:04

Lawrence LeBlond for redOrbit.com - Your Universe Online Much of what we know about the Mammoth may be challenged after new research from a Dutch team has found evidence that the massive mammal may have driven itself to extinction due to inbreeding. The evidence comes from an unusual feature found in some mammoth fossils taken from the North Sea. This unusual feature suggested to the research team, led by paleontologist Jelle Ruemer of the Natural History Museum Rotterdam, the...

Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

Eurasian Beaver Diversity In Question
2014-02-19 09:53:51

Brett Smith for redOrbit.com - Your Universe Online Long-prized for their thick fur, the cuddly Eurasian beaver has been hunted by humans for thousands of years and a new genetic study from a large group of international researchers has found that predation by humans has significantly cut down the genetic diversity of these animals. “While beaver populations have been growing rapidly since the late 19th century when conservation efforts began, genetic diversity within modern beaver...

Construction Workers Unearth 10,000-Year-Old Mammoth Tusk
2014-02-13 10:46:27

Ranjini Raghunath for redOrbit.com - Your Universe Online A rare, 10,000-year-old mammoth tusk has been discovered by a group of construction workers at a private construction site in the south Lake Union region of Seattle. The workers stopped working when their digging unearthed the intact fossil dating back to the Ice Age. Paleontologists believe that it must have belonged to the Columbian mammoth, Mammuthus columbi. The tusk was found on private property, but the Burke Museum of...

Woolly Mammoths And Other Megafauna Suffered From A Loss Of Plant Diversity
2014-02-06 09:29:49

[ Watch the Video: Diet Changes Killed Off Woolly Mammoths ] Brett Smith for redOrbit.com - Your Universe Online Scientists have put forth many theories on why woolly mammoths and other large animals went extinct around 10,000 years ago, from the devastating effects of a comet impact to overhunting by humans. A new DNA-based study published in the journal Nature has found that the flowering plants these “megafauna” depended on disappeared from northern Asia and North America...

Genes And Calls Reveal Greater Diversity Of Amazon Frog Species
2014-01-15 15:12:22

Pensoft Publishers Amazonian biodiversity has been studied for hundreds of years. Early explorers of Amazonian plants and animals included renowned naturalists of the stature of Alexander von Humboldt and A. R. Wallace. Despite this long history of exploration, new studies are resulting in the discovery of a large number of new species. The key of these discoveries lies in the use of advanced new tools for species detection. The study, published in the open access journal ZooKeys, found...

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...

Partial Skeleton Discovery Suggests Ruggedly Built, Tree-climbing Human Ancestor
2013-12-06 06:35:35

University of Colorado Denver A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists have discovered. Researchers found a partial skeleton -- including arm, hand, leg and foot fragments -- dated to 1.34 million years old and belonging to Paranthropus boisei at the Olduvai Gorge World Heritage fossil site in Tanzania. The find, published in the latest...

Generation Length For Mammals Is An Essential Reference Point For Conservation Studies
2013-11-13 14:21:28

Pensoft Publishers Life history traits are the basic ecological descriptors of a species. These include physical traits, such as body mass and physiological traits, such as reproductive rate. Ecologists have investigated the variation in life history traits and their role in determining the response of species to changing conditions, such as climate change, as well as to anthropogenic stressors. Generation length is one of the most studied among such traits. It represents the age at...

The Waitoreke is a cryptid from New Zealand described as being otter-like. Its name derived from “Wai” is a Maori word for water. The rest of the word has different translations, but the common one is “toreke,” which means to disappear. Together the name could translate into “disappears into water” or another translation is a “disappearing water specter.” The usual description is a small otter-like creature about the size of a cat. It has brownish short fur and short...

Red Rail, Aphanapteryx bonasia
2013-10-02 13:35:50

The Red Rail (Aphanapteryx bonasia) is an extinct and flightless rail. It was native to the Mascarene island of Mauritius, east of Madagascar within the Indian Ocean. It had a close relative on Rodrigues Island, the likewise extinct Rodrigues Rail, with which it’s sometimes considered congeneric. Its relationship with other rail isn’t clear. Rails frequently evolve flightlessness when adapting to isolated islands. It was slightly larger than a chicken and had reddish and hair-like...

Panthera leo spelaea
2012-11-16 15:34:04

Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...

Short-faced Bear, Arctodus simus
2012-04-27 19:45:45

The short-faced bear is an extinct genus of bears that was native to North America during the Pleistoscene era. Other common names include Arctodus and the bulldog bear. There are two subspecies of the short-faced bear, and one of them, Aroctodus simus, is thought to have been the largest terrestrial mammal on earth. Placed into a group of bears known as running bears or the tremarctine bears, this genus was found in Europe and the Americas. The earliest member of the tremarchtine group,...

The American lion (Panthera leo atrox or P. atrox) is also known as the North American lion, American cave lion, or Naegele’s giant jaguar. It is an extinct species that was native to North America and the northwestern parts of South America during the Pleistocene era. It lived up to eleven thousand years ago.
