Shifting weather patterns drove miocene grassland expansion
It's hard enough to know what happened in the distant past, but understanding why it happened requires some serious detective work. Between five and ten million years ago, grasslands began squeezing out forests and savannah across the tropics and subtropics, a change that may have driven the evolution of large grazing animals. What drove the botanical shift has been much less clear. By comparing several information sources, Brown University geologists have built a solid case that declining rainfall and shifting weather patterns were the primary culprits.
Ancient americans liked it hot. Smithsonian study traces mexican cuisine roots to 1,500 years ago
One of the world's tastiest and most popular cuisines, Mexican food also may be one of the oldest.
From rags to riches, or how undergarments improved medieval literacy
Thought the invention of the printing press led to an upsurge in literacy rates in the later Middle Ages? Wrong, according to some historians of communication, who believe that paper was more important than printing.
New research proves single origin of humans in Africa
New research published in the journal Nature (19 July) has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world.
Ice age survivors in Iceland
Many scientists believe that the ice ages exterminated all life on land and in freshwater in large parts of the Northern Hemisphere, especially on ocean islands such as Iceland. Scientists at Holar University College and the University of Iceland have challenged that belief, at least when looking at groundwater animals.
U-m paleontologist part of international team studying remarkably well-preserved baby siberian mammothPrivacy protection software utilities
University of Michigan paleontologist Daniel Fisher just returned from Siberia where he spent a week as part of a six-member international team that examined the frozen, nearly intact remains of a 4-month-old female woolly mammoth.Did you know that all your internet history can be reviewed by anyone with access to simple free tool available online. The internet brings with it many advantages and disadvantages.
Rise of dinosaurs not so rapid after all
Fossils discovered in the oft-painted arroyos of northern New Mexico show for the first time that dinosaurs and their non-dinosaur ancestors lived side by side for tens of millions of years, disproving the notion that dinosaurs rapidly replaced their supposedly outmoded predecessors.
Did pterosaurs feed by skimming?
In order to envisage the behaviors and lifestyles of now extinct animals, palaeontology often relies on extrapolating from modern species. Scientists identify shared anatomical features and infer from these shared ways of life.
Science steps in to discover wonders of Toe-Tankhamun
An artificial big toe attached to the foot of an ancient Egyptian mummy could prove to be the world's earliest functional prosthetic body part, say scientists.
Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs.

Fossils older than dinosaurs reveal pattern of early animal evolution on earth
The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago.
Beyond mesopotamia: a radical new view of human civilization
A radically expanded view of the origin of civilization, extending far beyond Mesopotamia, is reported by journalist Andrew Lawler in the 3 August issue of Science.
Link between sunspots, rain helps predict disease in east africa
A new study shows that sunspot cycles can be used to predict heavy rains, flooding and subsequent disease outbreaks in East Africa.
Exciting new kenyan fossils challenge established views on early evolution of our genus homo
Two new fossils, described in the journal Nature, cast fresh light on a little understood and important period of human prehistory at the dawn of our own genus, Homo. The new fossils were discovered by the Koobi Fora Research Project, an international group of scientists directed by mother-daughter team Meave and Louise Leakey, and affiliated with the National Museums of Kenya (NMK).
T. Rex quicker than becks, say scientists
T. rex may have struggled to chase down speeding vehicles as the movie Jurassic Park would have us believe but the world's most fearsome carnivore was certainly no slouch, research out today suggests.
Archaeology team discovers first ancient manioc fields in americas
A University of Colorado at Boulder team excavating an ancient Maya village in El Salvador buried by a volcanic eruption 1,400 years ago has discovered an ancient field of manioc, the first evidence for cultivation of the calorie-rich tuber in the New World.
New research challenges previous knowledge about the origins of urbanization
Ancient cities arose not by decree from a centralized political power, as was previously widely believed, but as the outgrowth of decisions made by smaller groups or individuals, according to a new study from researchers at Harvard University, the University of Cambridge, and the University of Edinburgh.
Architects of angkor's downfall
The architects of Cambodia's famed Angkor – the world's most extensive medieval "hydraulic city" – unwittingly engineered its environmental collapse, says research by UNSW scientists and a team of international scholars.
Pigs don't fly, but they do migrate
Ancient DNA harvested from pigs has allowed scientists, for the first time, to accurately determine the arrival of early farmers into Europe 11,000 years ago during the latter part of the Stone Age.
260 million-year-old reptiles from russia possessed the first modern ears
The discovery of the first anatomically modern ear in a group of 260 million-year-old fossil reptiles significantly pushes back the date of the origin of an advanced sense of hearing, and suggests the first known adaptations to living in the dark.
