Neural Crest Hypothesis Could Explain Why Domestic Mammals Share Characteristic Traits
2014-07-14 03:02:44

Genetics Society of America More than 140 years ago, Charles Darwin noticed something peculiar about domesticated mammals. Compared to their wild ancestors, domestic species are more tame, and they also tend to display a suite of other characteristic features, including floppier ears, patches of white fur, and more juvenile faces with smaller jaws. Since Darwin's observations, the explanation for this pattern has proved elusive, but now, in a Perspectives article published in the journal...

Human's Primate Cousins Also Pass Intelligence Through Their Genes
2014-07-10 15:25:30

Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that genetic factors for intelligence can be passed on in humans, but a new study shows that inherited intelligence also extends to our primate cousins – namely chimpanzees. Published in the journal Current Biology, the study showed environmental factors in determining a chimp’s intelligence may be less important than previously thought. "As is the case in humans, genes matter when it comes to...

In this week's Caught On, the popular website explores how video can help solve mysteries: three separate surveillance videos help police close in on unexplained car thefts, and amateur video helps marine biologists understand the enigma of the Orca's aggressive behaviour towards great white sharks. Toronto, ON (PRWEB) July 09, 2014 Caught On Magazine demonstrates how surveillance and amateur video is helping police, scientists and even distraught moms solve out-of-sight...

Inner Ear Fossil Shakes Up The Understanding Of Human Evolution
2014-07-08 12:25:28

Brett Smith for redOrbit.com - Your Universe Online Originally thought to be a sequential progression, human evolution has been shown to include a rich tapestry of species that interbred over thousands of years. A new study from Washington University in St. Louis has revealed yet another twist in this intricate story of our evolution. Based on the re-examination of an approximately 100,000-year-old early human skull found in Northern China, the new study discovered an inner-ear...

New Study Finds Ocean Ecosystems Naturally Engineered By Whales
2014-07-03 14:58:31

Brett Smith for redOrbit.com - Your Universe Online Whales have often been viewed as the lonely nomads of the seas, but a new report has found that these large mammals are actually great engineers of marine ecosystems. Published in Frontiers in Ecology and the Environment, the new study reviewed several decades of research on whales from around the world and found they play a powerful and positive role with respect to ocean function, global carbon storage, and ecosystem productivity....

PLOS Isolated dolphin populations may be vulnerable to environmental change New study estimating population genetic structure of little-known dolphins inhabiting Western Australia's north coast highlights vulnerability, according to a study published in the open-access journal PLOS ONE by Alex Brown from Murdoch University and colleagues. Australian snubfin and humpback dolphins occur throughout tropical coastal waters of northern Australia, but little is known of their abundance or...

tibetans and denisovans

redOrbit Staff & Wire Reports - Your Universe Online A gene acquired from an extinct cousin of modern humans is responsible for helping Tibetans adapt to high altitudes, according to new research published online by the weekly science journal Nature on Wednesday. Scientists from the University of California, Berkeley and Chinese genomics organization BGI-Shenzen found that Tibetans acquired the ability when their ancestors mated with Denisovans or individuals related to the...

redOrbit Staff & Wire Reports - Your Universe Online In less than 100 years, global warming’s impact on the sea ice where emperor penguins breed will result in the loss of at least one-fifth of the species’ population, according to new research appearing in the June 29 edition of the journal Nature Climate Change. There are currently 600,000 emperor penguins living in Antarctica and populations in 45 known colonies are expected to increase slightly by 2050 before declining over...

Monkeys Have Undergone Evolution In Facial Appearance To Avoid Interbreeding
2014-06-27 03:34:36

New York University Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species, researchers from New York University and the University of Exeter have found. Their research provides the best evidence to date for the role of visual cues as a barrier to breeding across species. "Evolution produces adaptations that help animals thrive in a particular environment, and over time...

SAINT JOHN, NB, June 12, 2014 /PRNewswire/ - The North Atlantic right whale was once hunted almost to extinction, but seventeen years ago Irving Oil began working with the New England Aquarium to protect this endangered species. The partnership is making a difference; the right whale population now exceeds five hundred, which is the highest population on record since research began three decades ago. Irving Oil's contribution to protecting the North Atlantic right whale helps...

Cetology
2013-10-02 11:21:29

Cetology is a branch of marine mammal science that studies about eighty species of dolphins, whales, and porpoise, all of which are classified within the Cetacea order. Cetologists, who practice cetology, work to understand the distribution, development, behavior, and other aspects of cetaceans. The study of cetaceans began in the Classical era. About 2,300 years ago, Aristotle documented details about some cetacean species, calling them mammals, while traveling on the Aegean Sea with...

Dall’s Porpoise, Phocoenoides dalliz
2013-08-29 10:15:35

Dall’s porpoise (Phocoenoides dalliz) can only be found in the North Pacific, with a range that includes the Sea of Japan and the Okhotsk and Bering Seas. This range extends to southern California in the east and to the southern waters of Japan in the west. When normal weather patterns change and waters become colder, this species can be found in in Baja, California, specifically in Scammon's Lagoon, and strays can occasionally be found in the Chukchi Sea. It prefers to reside in cold...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

The North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...

Con Rit

The con rit is a mythical creature of the oceans around southeast Asia, mainly off the coast of Vietnam. It is considered to be a type of sea serpent but with a strange appearance. Vietnamese folklore considers the con rit as a water dragon. In Vietnamese, the word con rit translates to millipede. Resembling a giant millipede, it is said to be about 50 feet long with jointed and armored segments, each being two to three feet in length with a pair of legs attached. The coloration of this...

Blainville's Beaked Whale, Mesoplodon densirostris
2013-08-17 13:31:16

Blainville’s beaked whale (Mesoplodon densirostris), also known as the dense-beaked whale, can be found in a large range that includes the warm and tropical waters of all oceans. It prefers to reside at depths between 1,600 and 3,000 feet and does not migrate. This species received its common name from Blainville, the man who classified it as Delphinus densirostris after studying a description of a piece of one individual’s nose located in the Paris Museum. In 1846, John Edward Gray...
