Height or flight? Fossil answers some questions about evolution of flight in dinosaurs, raises others
Paleontologists have long theorized that miniaturization was one of the last stages in the long series of changes required in order for dinosaurs to make the evolutionary "leap" to take flight and so become what we call birds. New evidence from a tiny Mongolian dinosaur, however, may leave some current theories about the evolution of flight up in the air.
Change from arid to wet climate in africa altered early human evolution
A drastic change in the climate of tropical Africa may have significantly driven early human evolution, an international team of scientists has found.
Velociraptor had feathers
A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science.
New research sheds light on 'hobbit'
An international team of researchers led by the Smithsonian Institution has completed a new study on Homo floresiensis, commonly referred to as the "hobbit," a 3-foot-tall, 18,000-year-old hominin skeleton, discovered four years ago on the Indonesian island of Flores. This study offers one of the most striking confirmations of the original interpretation of the hobbit as an island remnant of one of the oldest human migrations to Asia.
Human ancestors more primitive that once thought
A team of researchers, including Herman Pontzer, Ph.D., assistant professor of physical anthropology in Arts & Sciences, has determined through analysis of the earliest known hominid fossils outside of Africa, recently discovered in Dmanisi, Georgia, the former Soviet republic, that the first human ancestors to inhabit Eurasia were more primitive than previously thought.
New method of studying ancient fossils points to carbon dioxide as a driver of global warming
A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.
New dinosaur species found near choteau
A dinosaur skeleton found 24 years ago near Choteau has finally been identified as a new species that links North American dinosaurs with Asian dinosaurs. The dinosaur would have weighed 30 to 40 pounds, walked on two feet and stood about three feet tall. The fossil came from sediment that's about 80 million years old.
Scientists uncover inca children's countdown to sacrifice
Hair samples from naturally preserved child mummies discovered at the world's highest archaeological site in the Andes have provided a startling insight into the lives of the children chosen for sacrifice. Researchers funded by the Wellcome Trust used DNA and stable isotope analysis to show how children as young as 6-years old were "fattened up" and taken on a pilgrimage to their death.
Toothy dinosaur newest to come out of southern utah
The newest dinosaur species to emerge from Grand Staircase-Escalante National Monument had some serious bite, according to researchers from the Utah Museum of Natural History at the University of Utah.
Scientists say sabretooth bit like a pussycat
In public imagination, the sabre-toothed cat Smilodon ranks alongside Tyrannosaurus rex as the ultimate killing machine. Powerfully built, with upper canines like knives, Smilodon was a fearsome predator of Ice-Age America's lost giants.

Fossil data plug gaps in current knowledge
Researchers have shown for the first time that fossils can be used as effectively as living species in understanding the complex branching in the evolutionary tree of life.
Newfound ancient african megadroughts may have driven the evolution of humans and fishes
From 135,000 to 90,000 years ago tropical Africa had megadroughts more extreme and widespread than any previously known for that region, according to new research.
New findings solve human origins mystery
An extraordinary advance in human origins research reveals evidence of the emergence of the upright human body plan over 15 million years earlier than most experts have believed. More dramatically, the study confirms preliminary evidence that many early hominoid apes were most likely upright bipedal walkers sharing the basic body form of modern humans.
European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses? What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis. Incredibly, this record exists, in the icecaps of the Arctic and Antarctic regions, and a European Science Foundation programme has a key role in deciphering it.
Aswan obelisk quarry more than meets the eye
The unfinished Obelisk Quarry in Aswan, Egypt, has a canal that may have connected to the Nile and allowed the large stone monuments to float to their permanent locations, according to an international team of researchers. This canal, however, may be allowing salts from ground water to seep into what has been the best preserved example of obelisk quarrying in Egypt.
Asu team detects earliest modern humans
Evidence of early humans living on the coast in South Africa 164,000 years ago, far earlier than previously documented, is being reported in the Oct. 18 issue of the journal Nature.
Colorful view for first land animals
When prehistoric fish made their first forays onto land, what did they see? According to a study published in the online open access journal, BMC Evolutionary Biology, it's likely that creatures venturing out of the depths viewed their new environment in full colour.

Scientists find how amber becomes death trap for watery creatures
Shiny amber jewelry and a mucky Florida swamp have given scientists a window into an ancient ecosystem that could be anywhere from 15 million to 130 million years old.
Fossil record supports evidence of impending mass extinction
Global temperatures predicted for the coming centuries may trigger a new 'mass extinction event', where over 50 per cent of animal and plant species would be wiped out, warn scientists at the Universities of York and Leeds.
