Can you be religious and accept evolution?

Can you be religious and accept evolution?

Evolution and its meaning in the future of organisms and the human being is a subject widely discussed in scientific and non-scientific literature. In the 19th century, Charles Darwin contributed a crucial idea to understand how species originate: natural selection. Since then, the debates have continued. His book From Him On the Origin of Species , published in 1859, opened […] … learn more→

Evolution: how Victorian sexism influenced Darwin’s theories – new research

Evolution: how Victorian sexism influenced Darwin’s theories – new research

Sex is an expensive business, biologically speaking. Finding a suitable mate takes time and energy. Offspring are also a huge investment of resources. But sex does offer a rewarding possibility: children who are fitter than their parents thanks to new and “better” combinations of genes. Darwin realised that many animal species therefore carefully select their […] … learn more→

What do aliens look like? The clue is in evolution

What do aliens look like? The clue is in evolution

Speculating about what aliens look like has kept children, film producers and scientists amused for decades. If they exist, will extra terrestrials turn out to look similar to us, or might they take a form beyond our wildest imaginings? The answer to this question really depends on how we think evolution works at the deepest […] … learn more→

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→
