In an emerging model of evolution, widely supported by scientists, different types of early humans, including Neanderthals, interbred and left their genetic traces with many of us today. It is a theory known in the scientific literature as “admixture between archaic and anatomically modern humans.”
Scientists have discovered the earliest known evidence of right-handedness in the fossil record, thanks to markings on an ancient set of teeth that once belonged to a Tanzanian primate.
A fossil fish found in Yunnan, China, has filled in a gaping hole in how researchers thought the vertebrate jaw evolved.
The 423-million-year-old specimen, dubbed Qilinyu rostrata, is part of an ancient group of armoured fish called placoderms.
Wolves in Canada, lions in the Serengeti or fishermen in the Southern Ocean, either hunt alone keeping the spoils to themselves or in packs sharing the bounty with others. Deciding whether to tell fellow predators about some tasty prey is not an easy decision and requires the predator to weigh up many pros and cons.
New research reveals Asian elephant societies to be less hierarchical than their African relatives.
In Africa, elephant societies are characterized by matriarchal leadership and a clear pecking order. Many scientists believed Asian elephants organized and interacted in similar ways.
What hurts one mouse, hurts every mouse.
That’s the conclusion of a new study examining the social transfer of pain in mice. When one group of mice was exposed to a painful stimulus, a completely unaffected group displayed the same kind of heightened sensitivity as the first. Given that mice are mammals like us, the effect could also exist in humans, as well as informing future pain research.
Mouse squeaks may have more in common with human speech than we realised. Tinkering with a gene associated with language in humans has been found to mess up mice’s mating calls.
The gene, called FOXP2, is one of the most-studied genes involved in human brain evolution. It was discovered in the 1990s in a study of a British family that had 16 relatives who had difficulty making certain mouth movements and complex sounds.
Whether it’s jet lag, a new work schedule, daylight saving time or just a Monday morning, shifting sleep schedules takes a toll. But scientists think they might have found a way to reset our internal timers that’s more than hot air.

Northwestern Medicine scientists have discovered circadian clocks in muscle tissue that control the muscle’s metabolic response and energy efficiency depending on the time of day.
A new study suggests that road rage affects women more than men, and that females are far more likely to lose their cool behind the wheel.
The researchers suggest that women have an instinctive ‘early warning system’ which dates back to our early female ancestors who had a sense of danger for threats.
Adolescents among humans and non-human animals alike are more inclined to engage in heightened risk-taking behavior, exploration and novelty seeking. Although these attributes provide adaptive value in enabling individuals to gain importance in the world, including independence from parents, if taken too far, this tendency could lead to potentially dangerous behavior
Mind gamers, here’s a strange little test for you. Which of these shapes is a bouba, and which is a kiki? And what does this have to do with the evolution of language?
An international research team says they have identified the physical source of depression in the brain in a new study.
