The Dino Dynasty Reconsidered
Our understanding of dinosaur lineage is flawed, says a new study that contends dinosaurs actually lived alongside their ancestors for tens-of-millions of years. And the possibilities for paleontological revision don't end there, as another study has cleared the way for yet more possibilities (as if we needed any more) as to how the dino dynasty ended so abruptly...

Dino Detectives Decode Death Dance
The peculiar pose - wide-open mouth, head thrown back and recurved tail - of many fossilized dinosaurs has led two paleontologists to challenge long established theories about how these creatures died...

Humans Took First Steps In Tree Tops
UK scientists say that our ability to walk upright developed from foraging for food in forest tree tops, not from walking on all fours on open land...

Permian Extinction Triggered Rise Of Complex Marine Organisms
While the Permian-Triassic extinction event wiped out an estimated 95 percent of marine species, it also laid the foundation for the explosive growth in complex marine organisms and ecosystems...

26 October 2006
Back To The Drawing Board For Human Migration Patterns
Human polyomavirus, a benign virus used as a marker for tracing human migration out of Africa, appears to be evolving much faster than previously thought, making it an unreliable yardstick and calling into question hundreds of previous studies that relied on it...

15 September 2006
Did Civilization Emerge Thanks To A Change In The Weather?
Using evidence from archaeological digs and the palaeoclimatic record, one scientist claims that significant changes in social organization have coincided with abrupt climate change. But this isn't about yet another ancient civilization collapsing. Rather, it's about the changes societies undergo as adaptive responses to climate change. In fact, what we call civilization may be the by-product of these social adaptations to environmental change...

Homo Sapiens Brow-Beaten By Neanderthals
We modern-day humans think that we're pretty good looking compared to our brow-ridged, potato-nosed Neanderthal relatives; but new findings indicate that perhaps it is we who are the evolutionary freaks...

Global Warming Behind Early Primate Diaspora?
What prompted early primates to travel between continents 55 million years ago has perplexed scientists for years. Could rapid global warming have been the driving force?

2 June 2006
Smoking Gun For Permian-Triassic Extinction Found
Scientists have found evidence of a meteor impact in Antarctica that they believe caused the biggest mass extinction in Earth's history and led to the rise of the dinosaurs...

Volcano Study Suggests Bronze Age History Needs Rewrite
History professors may need to revise their lecture notes thanks to new evidence that disputes some commonly held assumptions about Aegean and Near Eastern civilization trade links...

Geologists Hope To Disprove Asteroid Mass Extinction Scenario
University of Leicester scientists suggest extraterrestrial theories are flawed and that more down to earth factors could have accounted for past mass extinctions...

Volcanic Clay May Have Served As Womb For Emergent Life
The mineral clay surrounding undersea hydrothermal vents has been found to not only incubate methanol, but also to trigger the creation of other biomolecules...
