Life on Earth may have originated not in warm tropical seas, but with weird tubes of ice — sometimes called “sea stalactites” — that grow downward into cold seawater near Earth’s poles, scientists are reporting Bruno Escribano and colleagues explain that scientists know surprisingly little about brinicles, which are hollow tubes of ice that can [...]
Humans have at least two functional networks in their cerebral cortex not found in rhesus monkeys. This means that new brain networks were likely added in the course of evolution from primate ancestor to human. These findings, based on an analysis of functional brain scans, were published in a study by neurophysiologist Wim Vanduffel (KU [...]
Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose? A study conducted at Michigan State University and published in the current issue of The American Naturalist investigates the evolutionary reasons why organisms go through developmental stages that appear unnecessary. “Many animals build tissues and structures they don’t appear [...]
Richard Leakey predicts skepticism over evolution will soon be history. Not that the avowed atheist has any doubts himself. Sometime in the next 15 to 30 years, the Kenyan-born paleoanthropologist expects scientific discoveries will have accelerated to the point that “even the skeptics can accept it.” “If you get to the stage where you can [...]
For generations, scientists have believed Africa was the cradle of mankind. Now a stunning archaeological discovery suggests our primitive ancestors left Africa to explore the world around 800,000 years earlier than was previously thought before returning to their home continent. It was there – hundreds of thousands of years later – that they evolved into [...]
The theory of evolution by natural selection is now scientific orthodoxy, but when it was unveiled it caused a storm of controversy, from fellow scientists as well as religious people. They criticised it for being short on evidence and long on assertion and Darwin, being the honest scientist that he was, agreed with them. He [...]
The first study into rarely documented ground-nest building by wild chimpanzees offers new clues about the ancient transition of early hominins from sleeping in trees to sleeping on the ground. While most apes build nests in trees, this study, published in the American Journal of Physical Anthropology, focused on a group of wild West African [...]
According to a news reel from China, a young boy there possesses the ability to see in the dark. Like a Siamese cat’s, his sky-blue eyes flash neon green when illuminated by a flashlight, and his night vision is good enough to enable him to fill out questionnaires while sitting in a pitch black room [...]
Most scientists believe that human beings evolved in Africa, then migrated from the continent to conquer the world. But researchers from the University of Tubingen in Germany believe that our ancestry might be more complicated – and significant parts of human evolution might have happened in Europe and Western Asia. The new theory comes after [...]
In December 2011, the Guardian posted this note to go with what looked like a living photograph of the newly discovered snub-nosed monkey from Myanmar: “R. strykeri has not yet been photographed in life. The image to the right is a reconstruction based on photographs of a related species and a specimen of the new [...]
