Evolution Discovery: No Social Distancing at the Beginning of Life

Discovery that bacterial biofilms behave like animal embryos sheds new light on the origin of life. Bacteria are a dominant form of life that inhabit every environment on Earth. This includes human bodies, where they outnumber our cells and genes and regulate our existence for good or bad. Bacter

These Two Bird-Sized Dinosaurs Evolved Bat-Like Wings, but Struggled to Fly

Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, researchers report today (October 22, 2020) in the journal iScience. Unable to compete with other tree-dwelling dinosaurs and early birds, they

Humans are born with brains ‘prewired’ to see words: Study finds connections to language areas of the brain — 

Humans are born with a part of the brain that is prewired to be receptive to seeing words and letters, setting the stage at birth for people to learn how to read, a new study suggests. Analyzing brain scans of newborns, researchers found that this part of the brain — called the ‘visual word form area’ (VWFA) — is connected to the language network of the brain.

Turbulent era sparked leap in human behavior, adaptability 320,000 years ago 

The first analysis of a sedimentary drill core representing 1 million years of environmental history in the East African Rift Valley shows that at the same time early humans were abandoning old tools in favor of more sophisticated technology and broadening their trade, their landscape was experiencing frequent fluctuations in vegetation and water supply that made resources less reliably available. The findings suggest that instability in their landscape was a key driver of human adaptability.
