Life on Earth still favours evolution over creationism

Charles Darwin’s Theory of Evolution, first published in 1859, offered a bold new explanation for how animals and plants diversified and still serves as the foundation underpinning all medical and biological research today. But the theory remains under attack by creationists in various parts of the world, particularly the US, Turkey, Indonesia and the Middle […] … learn more→

How small birds evolved from giant meat eating dinosaurs

Spectacular transitional fossils, many from northern China, provide overwhelming evidence that dinosaurs evolved into birds and thus didn’t all perish when the deadly meteorite struck at the end of the Cretaceous period. We now know that many bipedal, meat-eating dinosaurs (theropods) – including relatives of T. rex and Velociraptor – were adorned with a variety […] … learn more→

Canine and able: how dogs made us human

What role have dogs played in human evolution? Woof … now there’s a question. Anthropologist Pat Shipman, in a recent issue of American Scientist, suggests dogs gave our human ancestors an advantage over Neanderthals when they arrived in Europe. Dogs, she argues, made a real difference to the success of the hunt. They respond to […] … learn more→

Not a one-way street: Evolution shapes environment

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, […] … learn more→

Earlier relatives may have climbed out of family tree

The first study into rarely-documented ground nest-building by wild chimpanzees has offered new clues about the ancient transition of early hominins – our “human-like” ancestors – from sleeping in trees to sleeping on the ground. While most apes build nests in trees, the study, published in the American Journal of Physical Anthropology, focused on a […] … learn more→

The discovery of fire: initial steps toward anthropogenic climate change

The evidence for a rapid shift in state of the terrestrial atmosphere-ocean system over the last two centuries (see figure 1) requires a deep time perspective, beyond events of the day. Tracing the original blueprints of anthropogenic effects on the terrestrial environments takes us back at least a million years to the time when – […] … learn more→

The answer to the riddle of which came first

Dinosaurs, the animal group that includes birds and their ancestors, laid eggs. This means that the ancestors of birds laid eggs long before chickens came about. Because we know so much about the evolution of life on Earth, this answer now seems obvious. But without fossils, and without understanding how evolution works, we could have […] … learn more→

Developments in evolutionary biology have a significant impact on the way we look at the world and ourselves in it. … learn more→

Evolution is written all over your face

Why are the faces of primates so dramatically different from one another? UCLA biologists working as \”evolutionary detectives\” studied the faces of 129 adult male primates from Central and South America, and they offer some answers in research published today, Jan. 11, in the early online edition of the journal Proceedings of the Royal Society […] … learn more→

Do we need a ‘science of evidence’?

Evidence is key to many topical debates such as global warming, evolution, the search for weapons of mass destruction, DNA profiling, and advances in science and medicine. A new book asks whether, considering the importance of evidence for so many disciplines, a general ‘science of evidence’ is possible – or even desirable. Evidence, Inference and […] … learn more→
