Evidence Found To Support Nocturnal Bottleneck Theory
2012-11-01 09:33:36

April Flowers for redOrbit.com - Your Universe Online Most species of diurnal mammals have retained the imprint of nocturnal life in their eye structures since the age of dinosaurs. According to a new study from The University of Texas at Austin and Midwestern University, anthropoid primates - including humans, monkeys and apes - are the only groups that deviate from this pattern. This study is the first to provide a large-scale body of evidence for the "nocturnal bottleneck theory,"...

Evolutionary Tree Of Life Goes Digital
2012-10-17 13:25:34

Brett Smith for redOrbit.com - Your Universe Online Evolutionary biologists have long envisioned creating a diagram, or tree of life, that would detail how different species have evolved from a common ancestry, but the task has been a daunting one for taxonomists who would need multiple reams of paper or computer screens to clearly show the evolutionary descent of each species. A research associate at the Imperial College London, however, has risen to the challenge and created OneZoom,...

Our Inner Reptile Hearts Found By Researchers
2012-09-14 12:08:19

The genetic building blocks behind the human heart´s subtle control system have finally been identified. An elaborate system of leads spreads across our hearts. These leads — the heart´s electrical system — control our pulse and coordinate contraction of the heart chambers. While the structure of the human heart has been known for a long time, the evolutionary origin of our conduction system has nevertheless remained a mystery. Researchers have finally succeeded in...

Evolutionary Debate Sheds Light On The Age Of Mammals
2012-08-28 13:48:56

April Flowers for redOrbit.com - Your Universe Online 65 million years ago, dinosaurs like Tyrannosaurus and Triceratops disappeared, leaving Earth open to the rise of mammals. These strange creatures are only distantly related to the mammals alive today. One of those unusual mammals, Ernanodon antelios, was only known from a single, highly distorted specimen until recently. This specimen raised more questions than it answered about habits and evolutionary relationships. In the most...

Shakedown - How To Dry A Furry Mammal
2012-08-20 11:34:13

Brett Smith for redOrbit.com - Your Universe Online In continuing a trend that has seen scientists looking to the mechanics of nature for inspiration, researchers at the Georgia Institute of Technology are studying the ways in which furry mammals shake themselves dry. The study – which involved 33 different animals, including 16 species and five dog breeds - found that furry mammals can shake 70 percent of the water off their bodies in just a fraction of a second. They also saw...

Fossilized Teeth Point To World’s Oldest Grasslands In Chilean Andes
2012-07-25 05:14:14

Brett Smith for redOrbit.com - Your Universe Online Two newly discovered and ancient rodent species, including the earliest known chinchilla, may have lived in the world´s oldest grasslands about 32.5 million years ago. The discovery and subsequent analysis of the teeth by an international team of researchers, which was published in the journal American Museum Novitates, supports previously collected evidence indicating that these animals once inhabited an open and dry environment...

New Zealand Reptile Chews Food Unlike Any Other On The Planet
2012-05-30 08:56:23

[ Watch the Video ] Scientists studying one of New Zealand´s most iconic reptiles have found that it chews its food in a way unlike any other animal on the planet, challenging the popular perception that complex chewing ability is linked to high metabolism. The tuatara, a beak-headed lizard-like reptile that is the sole living member of a family of reptiles that was widespread during the age of the dinosaurs, is able to slice through its food like a “steak knife” would....

A new study led by Carrie Schloss, an analyst in environmental and forest sciences at the University of Washington, finds that nine percent of the Western Hemisphere's mammals, and nearly forty percent in particular regions, will fall victim to the changing climate. Some mammals are merely too slow to escape climate change in their natural habitats and are unable to move into different areas. The study seeks to understand if the mammals can actually adapt to these conditions by moving or not....

An analysis of skeletal remains has provided new evidence that humans made it to the Western Hemisphere during the last ice age, where they lived alongside giant, now-extinct mammals, claims a new study published online Thursday in the Journal of Vertebrate Paleontology. University of Florida researchers used rare earth element analysis in order to measure the concentration of naturally occurring metals absorbed during fossilization in human and mammal remains discovered in south Florida...

Eye Size Determined By Maximum Running Speed In Mammals
2012-05-02 10:19:28

Image Credit: Photos.com ___ Maximum running speed is the most important variable influencing mammalian eye size other than body size, according to new research from The University of Texas at Austin. Species with larger eyes usually have higher visual acuity, says Chris Kirk, associate professor in the Department of Anthropology. But what are the ecological factors that cause some mammals to develop larger eyes than others? "If you can think of mammals that are fast like a cheetah...

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...
