Your mother was right: Fish really is "brain food." And it seems that even pre-humans living as far back as 2 million years ago somehow knew it. A team of researchers that included Johns Hopkins University geologist Naomi Levin has found that early hominids living in what is now northern Kenya ate a wider variety of foods than previously thought, including fish and aquatic animals such as turtles and crocodiles. Rich in protein and nutrients, these foods may have played a key role in the...

Could help scientists track paleoclimate, determine whether dinosaurs and other species were warm- or cold-blooded Was Tyrannosaurus rex cold-blooded? Did birds regulate their body temperatures before or after they began to grow feathers? Why would evolution favor warm-bloodedness when it has such a high energy cost? Questions like these"”about when, why, and how vertebrates stopped relying on external factors to regulate their body temperatures and began heating themselves...

New fossil material redefines Azendohsaurus as a peculiar early reptile Azendohsaurus just shed its dinosaur affiliation. A careful new analysis of A. madagaskarensis"”this time based on the entire skull rather than on just teeth and jaws"”aligns this 230-million-year-old animal with a different and very early branch on the reptile evolutionary tree. Many aspects of Azendohsaurus are far more primitive than previously assumed, which in turn means that its plant-eating adaptations,...

The squirrels littering your lawn with acorns as they bound overhead will live to plague your yard longer than the ones that aerate it with their burrows, according to a University of Illinois study. Scientists know from previous studies that flying birds and bats live longer than earthbound animals of the same size. Milena Shattuck and Scott Williams, doctoral candidates in anthropology, decided to take a closer look at the relationship between habitat and lifespan in mammals, comparing...

Scientists have discovered that air flows in one direction as it loops through the lungs of alligators, just as it does in birds. The results, published in this week's issue of the journal Science, suggest that this breathing method may have helped dinosaurs' ancestors dominate Earth after the planet's worst mass extinction 251 million years ago. Before and until about 20 million years after the extinction--called "the Great Dying" or the Permian-Triassic extinction--mammal-like reptiles...

Abandon any notion that the duck-billed platypus is a soft and cuddly creature -- maybe like Perry the Platypus in the Phineas and Ferb cartoon. This platypus, renowned as one of the few mammals that lay eggs, also is one of only a few venomous mammals. The males can deliver a mega-sting that causes immediate, excruciating pain, like hundreds of hornet stings, leaving victims incapacitated for weeks. Now scientists are reporting an advance toward deciphering the chemical composition of the...

A new look at limbs changes understanding of early carnivore locomotion More than a hundred years after its discovery, the limbs and vertebrae of a fossil have been pulled off the shelf at the American Museum of Natural History to revise the view of early carnivore lifestyles. Carnivores"”currently a diverse group of mostly meat-eating mammals like bears, cats, raccoons, seals, and hyenas"”had been considered arboreal in their early evolutionary history. But now that the skeleton...

Monkey species will become "Ëœincreasingly at risk of extinction' because of global warming, according to new research. It reveals that populations of monkeys and apes in Africa that depend largely on a diet of leaves may be wiped out by a rise in annual temperatures of two degrees Celsius. The study by researchers from Bournemouth University, Roehampton University and the University of Oxford suggests that the species most at risk are the already endangered gorillas and colobine...

If Earth is headed for a mass extinction like the previous five, in which more than 75 percent of all species were wiped out, then North American mammals are one-fifth to one-half the way there, according to a University of California, Berkeley, and Pennsylvania State University analysis. Many scientists warn that the perfect storm of global warming and environmental degradation - both the result of human activity - is leading to a sixth mass extinction equal to the "Big Five" that have...

Mammals may be nearly half way toward mass extinction If the planet is headed for another mass extinction like the previous five, each of which wiped out more than 75 percent of all species on the planet, then North American mammals are one-fifth to one-half the way there, according to a University of California, Berkeley, and Pennsylvania State University analysis. Many scientists warn that the perfect storm of global warming and environmental degradation "“ both the result of human...

Echidna, Tachyglossidae
2014-06-19 07:53:10

Tachyglossidae is a family that holds eight species of echidnas, also known as spiny anteaters, four of which are known only from fossils. The remaining four species, which include the platypus, can only be found in New Guinea and Australia. They prefer to reside in wooded areas and can be found under piles of vegetation, roots, and occasionally inside the burrows of other animals. This family is named after the "Mother of All Monsters" in Greek mythology, although the two do not resemble...

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...
