Mammoth Skull Discovered in Southeastern Idaho

Mammoth Skull Discovered in Southeastern Idaho

A part of a mammoth skull and tusks have been discovered in southeastern Idaho, and specialists believe that an extremely rare complete skeleton might be located there. Professionals guess the mammoth was about 15 years old and lived around 80,000 to 125,000 years ago in what was a kind of  savanna type plain that was […]

Climate Change Is Causing Alpine Goats to Shrink

Climate Change Is Causing Alpine Goats to Shrink

New research has shown that the Alpine Chamois, a species of mountain goat, has begun to shrink in response to rising temperatures and climate change. According to the results of the study, a young Chamois now weighs roughly 25 percent less than those of the same age measured in 1980. The research, which was funded by […]

Kangaroos Did Not Always Hop?

Kangaroos Did Not Always Hop?

On Wednesday, scientists who conducted an analysis of the fossilized bones of a group of large extinct kangaroos came to a somewhat startling conclusion. After doing a statistical and biomechanical analysis of the remains, the scientists concluded that the ancient kangaroos likely did not hop. The group of extinct ‘roos that the scientist studied were […]

Red Fox Genome Reveals Evolutionary History

Red Fox Genome Reveals Evolutionary History

New work on the genome of the red fox has revealed much about the evolutionary history of this remarkably successful small carnivore, which ranges across much of North America and Eurasia and into North Africa. Where previous studies relied on maternal lines, scientists from the University of California, Davis, used DNA from across the whole […]

The Silken Reef: Social Spiders and Evolution by Group Selection

The Silken Reef: Social Spiders and Evolution by Group Selection

A tiny spider that lives in groups may soon be at the center of one of the more important debates in biology, namely the question of whether or not evolution can be said to occur at the level of the group. Colonies of these social spiders, Anelosimus studiosus, succeed or fail based on having the […]

Group Selection in Social Spiders?

Group Selection in Social Spiders?

An old but long-simmering controversy in biology stands to be reignited by a new study claiming that a species of social spider, Anelosimus studiosus, exhibits so-called “group selection.” The scientists found evidence that a key feature in A. studiosus colonies, the ratio of aggressive to docile females, is optimized in accordance with the abundance of […]

New Species of Poison Dart Frog Discovered

New Species of Poison Dart Frog Discovered

A new species of poison dart frog, Andinobates geminisae, has been discovered in Panama near that country’s Caribbean coast. The bright orange frog measures only about half an inch (12.77 millimeters) in length, and is described as having a rather distinct call in comparison with those of its closest relatives. A. geminisae was first collected […]

GMOs: Massive Feeding Study Finds No Negative Impacts

GMOs: Massive Feeding Study Finds No Negative Impacts

Genetically modified organisms (GMOs) have been scrutinized in a new study that evaluated the effects of introducing them into livestock feed. The massive study reviewed so-called “feeding studies” for the period from 1983-2011, and found no negative impacts of GMOs on livestock health or on the nutritional value of the resulting animal products. The review […]

The Rise of the ‘Werewolf Cat’

The Rise of the ‘Werewolf Cat’

The new big thing in cats just might be the rise of the “werewolf cat,” even though most of the time; people seem to choose felines that have robust, full coats of fur. They use to shun the mangier looking of the species, which had tangled, thin hair but it appears that could be changing. The […]

Fossil Shows Early Evolution of Complex Multicellular Life

Fossil Shows Early Evolution of Complex Multicellular Life

Tiny spheroidal fossils from a formation in South China provide insights into the early evolutionary history of complex multicellular life, according to scientists from Virginia Tech and the Chinese Academy of Sciences. While the exact identity and affinities of these 600 million-year-old fossils remains unclear, there is evidence that they are multicellular organisms with differentiated […]
