Rats Have Best Bite Of Rodent World
2012-04-30 07:36:42

Scientists at the University of Liverpool have found that mice and rats have evolved to gnaw with their front teeth and chew with their back teeth more successfully than rodents that 'specialize' in one or other of these biting mechanisms. Researchers designed a computer model to simulate the bite of rats to understand whether their skull shape or muscle arrangement was a major factor in their evolutionary success and global dominance, making them one of the most common pest species in the...

Evolution In An Island, The Secret For A Longer Life
2012-04-25 07:50:24

ICP researchers published today in the 'Proceedings of the Royal Society B' one of the first fossil-based evidences supporting the evolutionary theory of ageing, which predicts that species evolving in low mortality and resource-limited ecosystems tend to be more long-lived. The study shows that the tooth height of endemic insular mammals is an indicator of longevity, and questions the use of this morphological characteristic as an exclusive indicator to infer the diet of fossil species,...

Mammal Diversity Aided In Survival Over Deep Time
2012-04-24 12:24:49

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

Leeches To Track Mammal DNA In Jungles
2012-04-24 06:10:55

Connie K. Ho for RedOrbit.com Researchers from Copenhagen Zoo and the University of Copenhagen have discovered a way to track mammals in the jungles of Southeast Asia. Scientists collected leeches from the jungles to analyze the blood and DNA of animals taken by the parasites. With this new method, researchers will be able to study the biodiversity of the mammals without having to track each one down. The findings, to be published in science journal Current Biology, allow scientists to...

Image 1 - Dinosaurs May Have Doomed Their Species By Laying Eggs
2012-04-18 14:10:50

New research suggests that the way dinosaurs reproduced could have led to their demise. According to research from the Zoological Society of London, dinosaurs became at risk when they began to lay eggs. Working together with colleagues, Daryl Codron and Marcus Clauss from the University of Zurich conducted this research into the possible beginning stages of the dinosaurs extinction. Their work has been published in the journal Biology Letters. The trouble could have been the sheer size of...

Omnivores Play For Both Teams
2012-04-17 10:34:47

Just because a bear prefers the taste of flesh today doesn´t mean it has always been so. A new study has investigated the previous eating habits of mammals, particularly omnivores, to discover how their eating habits have evolved. Large cats, such as lions and tigers are known carnivores, eating meat almost exclusively. On the other hand, other mammals such as cows, deer, and other livestock are herbivores, eating bark, grass, and fruit. Eating a mixture of plants and meat, however,...

Almost all non-human mammals eat placenta for good reasons. Are we missing something? A paper by neuroscientists at the University at Buffalo and Buffalo State College suggests that ingestion of components of afterbirth or placenta -- placentophagia -- may offer benefits to human mothers and perhaps to non-mothers and males. They say this possibility does not warrant the wholesale ingestion of afterbirth, for some very good reasons, but that it deserves further study. Mark Kristal,...

Endocannabinoids motivated the evolution of exercise In the last century something unexpected happened: humans became sedentary. We traded in our active lifestyles for a more immobile existence. But these were not the conditions under which we evolved. David Raichlen from the University of Arizona, USA, explains that our hunter-gatherer predecessors were long-distance endurance athletes. 'Aerobic activity has played a role in the evolution of lots of different systems in the human body,...

Mammals Flourished During Last 20 Million Years Of Dinosaur Era
2012-03-15 13:49:21

New research suggests that some mammals flourished during the last 20 million years of the dinosaurs' reign. University of Washington paleontologist Gregory P. Wilson suggests the multituberculates, a rodent-like creature, did so well during this time because they developed numerous tubercles on their back teeth that allowed them to feed on flowering plants back then. “These mammals were able to radiate in terms of numbers of species, body size and shapes of their teeth, which...

Conventional wisdom holds that during the Mesozoic Era, mammals were small creatures that held on at life's edges. But at least one mammal group, rodent-like creatures called multituberculates, actually flourished during the last 20 million years of the dinosaurs' reign and survived their extinction 66 million years ago. New research led by a University of Washington paleontologist suggests that the multituberculates did so well in part because they developed numerous tubercles (bumps, or...

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...
