U.S. scientists say they have discovered marine mammals are being exposed to a cocktail of pesticides, as well as new contaminants. In what's called the most extensive study of pollutants in marine mammals' brains, Woods Hole Oceanographic Institute scientists found the animals are exposed pesticides such as DDT and PCBs, as well as contaminants such as brominated flame retardants. Eric Montie, lead author of the study, performed the research in collaboration with Mark Hahn and Chris Reddy of...

47 Million Year Old Primate Fossil Set to Revolutionize Understanding of Human Evolution -- HISTORY SPECIAL DOCUMENTING DISCOVERY TO AIR MAY 25 AT 9PM ET/PT -- NEW YORK, May 19 /PRNewswire/ -- HISTORY, together with the University of Oslo and the Senckenberg Research Institute, today reveal a landmark scientific find: the 47 million year old fossilized remains of a primate. The most complete fossil primate ever found, the young female specimen -- known as "Ida" -- is set to revolutionize...

THE LINK: Uncovering Our Earliest Ancestor - Little, Brown and Company, May 20, 2009 NEW YORK, May 19 /PRNewswire/ -- Scientists have announced today the discovery of a 47-million-year-old human ancestor. Discovered in the Messel Pit, Germany, the fossil is twenty times older than most fossils that explain human evolution. Known as "Ida," the fossil is a transitional species, showing characteristics of the very primitive nonhuman evolutionary line (prosimians, such as lemurs), but even more...

A study conducted by three U.S. universities suggests some Michigan mammals are moving northward, apparently in response to climate change. Scientists from the University of Michigan, Ohio's Miami University and Michigan State University said the northward range expansion of the historically southern species might have a significant impact, with similar movements reported in Wisconsin, Canada and at Yosemite National Park. We're talking about the commonest mammals there, mammals that have...

During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical appearance, let alone analyze their evolutionary dynamics, when molecular techniques had already invalidated that approach? With more than a few heads in the audience nodding their agreement, Jablonski, the William Kenan Jr. Professor in Geophysical Sciences, saw more work to be done. The...

Scientists from Canada and the U.S. have discovered the skeleton of a previously unknown web-footed carnivore in Canada's Arctic. The researchers said their discovery sheds light on how seals developed from land-based mammals. The primitive animal, known as Puijila darwini, measured around 43 inches from nose to tail, and had a body similar to that of an otter, but a skull akin to a seal. New research suggests Puijila is a "missing link" in the evolution of the group that today includes...

Pangolins in Southeast Asia are dwindling in numbers due to poaching activities, the Association of Southeast Asian Nations (ASEAN) Wildlife Enforcement Network said on Tuesday. Poachers have long sought after the scaly anteaters for their meat, which is used for consumption. They also use their scales for traditional medicines. "More than a 100 tons of smuggled pangolin meat heading to China was confiscated in the region last year but that is only 10 to 20 percent of the amount of Pangolin...

A new University of Florida study based on DNA analysis from living flowering plants shows that the ancestors of most modern trees diversified extremely rapidly 90 million years ago, ultimately leading to the formation of forests that supported similar evolutionary bursts in animals and other plants. This burst of speciation over a 5-million-year span was one of three major radiations of flowering plants, known as angiosperms. The study focuses on diversification in the rosid clade, a group...

The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. According to a new study published in The American Naturalist, mammals that hibernate or that hide in burrows are less likely to turn up on an endangered species list. The study's authors believe that the ability of such "sleep-or-hide" animals to buffer themselves from changing environments may help them avoid extinction. The idea that sleepers and hiders may have a survival advantage...

Colugos (aka flying lemurs) "” the closest living relatives of primates most notable for their ability to glide from tree to tree over considerable distances "” are more diverse than had previously been believed, according to a new report published in the November 11th issue of Current Biology, a Cell Press publication. Primates are most familiarly represented by monkeys and apes, the group including humans. Scientists had recognized just two species of these enigmatic mammals,...

The Aardvark, Orycteropus afer, sometimes called the "˜antbear', is a medium-sized mammal native to Africa. It lives south of the Sahara desert where there is suitable habitat for them to live. It prefers savannas, grasslands, woodlands and bush. They are not found in deserts but are found in areas where there is a good supply of ants and termites. The most distinctive characteristic of the Aardvark is their teeth. Instead of having a pulp cavity, they have a number of thin tubes of...

The European Mole, Talpa europaea, is a mammal of the order Soricomorpha. This mole lives in an underground tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions the displaced earth is pushed to the surface, resulting in the characteristic "mole hills". It has a cylindrical body and is around 5 1/4 inches (12 cm) long. Females are typically smaller than males. The eyes are small, and hidden behind fur. Its ear is just a small ridge...

The platypus is a semi-aquatic endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family and genus, though a number of related species have been found in the fossil record. The unique appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some...
