Researchers at the American Museum of Natural History (AMNH), in New York City, led by Ross MacPhee, recently returned home from Antarctica with a cache of over 200 fossils belonging to marine reptiles, fish, birds, plants, and maybe even dinosaurs, possibly the largest such collection ever. The team has been trave... |

A new scientific discovery pushes the time frame when the first placental mammals evolved back an estimated 35 million years. This conclusion is based on the discovery of an excellently-preserved fossils that was discovered in northeastern China. Placental mammals are animals that have a placenta. This structure help... |

According to the conclusions of a new scientific investigation, it would appear that fish and mammals use their tongues in entirely different ways when chewing. This is what primarily underlies the differences between the two types of creatures. Researchers at the Brown University say that fish exhibit a preference t... |

The huge brain that mammals have – in comparison to the size of their bodies – may have grown to these dimensions as a result of the enlargement of the olfactory bulb and the smell-processing areas of the cortex. The finding was made by studying a species that lived millions of years ago.
The reason w... |

Strangely, few people thought that the mighty dinosaurs may have had such a common problem as lice. Yet experts seem to believe that this was precisely the case, especially as far as the feathered of the giant lizards went. Dinosaurs are now believed to have been affected by the same type of parasites as young childr... |

In a groundbreaking new study, researchers in the United States were able to demonstrate that the heart of newborn mammals is capable of healing itself even after suffering moderate to large damage. In the experiments, which were conducted on unsuspecting lab mice, the researchers extirpated a portion of an animal�... |

Dinosaurs once ruled our planet but after they disappeared 65 million years ago, it was the time for mammals to thrive, the proof being that there were some that even got a thousand times bigger than they used to be.This is the first study that actually proves that there was a new pattern of increased body size in ma... |

In a strange twist, scientists recently managed to uncover the remains of a dinosaur that appears to have been killed off while searching for prey. The creature was most likely clawing at the ground, getting ready to unearth a buried “snack,” most likely a mammal. Dated back to 75 million to 80 million ye... |

In a new scientific study, researchers have broken new ground in their understanding of how birds and mammals may be connected evolutionarily. The investigators managed to discover that a common learning mechanism is at work in both the bird and mammalian brain, and that the same pathways are used, to some extent, in... |

Researchers have recently determined that lab mice can eliminate trace amounts of the painkiller morphine, if they are injected with precursor chemicals to the drug. The finding implies that mammals are capable of synthesizing the complex compound inside the body, which may help them cope with various types of pain. ... |

For nearly 200 million years, dinosaurs reigned supreme. They were spread out across most locations on the planet, and there were no creatures that could challenge their domination except, of course, other dinosaurs. Yet, some 65 million years ago, an asteroid impact managed to wipe them all out. Some studies suggest... |

Maotherium asiaticus is the name Chinese and American researchers gave to a newly discovered fossil species, which lived in the Liaoning Province of China some 123 million years ago. The chipmunk-sized creature was found in the Yixian Formation, a very rich fossil bed that had yielded countless amazing discoveries ov... |

According to a new study conducted by experts at the University of California in Los Angeles (UCLA), mammals can now be declared the winners of the evolutionary race, outclassing reptiles in the fight for survival. Fish and birds also moved ahead of reptiles, each exhibiting large species diversity, which means that ... |

According to a new report released on Thursday by the International Union for Conservation of Nature, some 869 species of plants and animals have gone extinct in the past 500 years, with an additional 17,000 more now at risk of disappearing as well. Additionally, the paper underlines the fact that the world's go... |

The Blue Brain Project is an initiative that was started by IBM and EPFL in July 2005, with the purpose of reverse-engineering a small portion of the mammalian brain, including that of humans. The ultimate goal of the research is to understand the functions and dysfunctions of the organ, by analyzing and simulating i... |

Experts know that the females of most species of mammals, including humans, stop producing eggs, known as oocytes, soon before birth, and that the number of eggs they are born with is the number they will have for the rest of their lives. Challenging this knowledge, researchers in China have recently announced that t... |

Thus far, scientists and naturalists have known that female birds are the most picky living things when it comes to their mates, but have never suspected that the same behavior could be found in mammals as well. But recent investigations into the matter seem to yield very interesting conclusions, in that it actually ... |

It's common knowledge that mammals, unlike for example reptiles, have warm blood and generate heat inside their bodies at all times. For many years, researchers in the field of evolution have been trying to decipher the mystery of this difference, and especially how warm-blooded creatures came to be in the first... |

The fossilized burrow found recently in Antarctica and dated to the Early Triassic epoch is thought to have belonged to tetrapods - land vertebrates with four legs or appendages resembling legs - and was created when a nearby river overflowed, filling it with fine sand that hardened later on. No remains of the animal... |

Scientists have recently found the oldest known fossil that indicates that reproduction through birth was encountered in vertebrate animals as early as 380 million years ago. The fossil belongs to an armored fish female that was about to give birth, but it perished and got fossilized along with the embryo inside it. ... |

Morning sickness could be rather annoying for most pregnant women, but it may in fact have the role of protecting the embryo. According to doctors, morning sickness is the sign of a healthy pregnancy, although it's not yet known if it leads to a successful one or not. Alternatively, it could be the effect of the... |
