The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly      (via sciencedaily.com)     Original source 

Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.

Smells like evolution: Fruit flies reveal surprises in chemical sensing      (via sciencedaily.com)     Original source 

New study reveals how gene expression shapes the diverse smelling and tasting abilities of different fly species. Most genes are surprisingly stable, but thousands have evolved to create unique olfactory landscapes. Sex differences in sensing are widespread and involve specific cell types in key tissues. The study provides insights into the evolution of sensory systems in general, with potential implications for understanding human olfaction.

How food availability could catalyze cultural transmission in wild orangutans      (via sciencedaily.com)     Original source 

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?

Rare 3D fossils show that some early trees had forms unlike any you've ever seen      (via sciencedaily.com)     Original source 

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

AI learns through the eyes and ears of a child      (via sciencedaily.com)     Original source 

Researchers have been skeptical that recent AI advances can tell us much about human learning and development. To address this, a team training an AI model, not on massive data, but on the input that a single child receives. Their findings showed that the model could learn a substantial number of words and concepts using limited slices of what the child experienced.

How did humans learn to walk? New evolutionary study offers an earful      (via sciencedaily.com)     Original source 

A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.

Researchers map genome for cats, dolphins, birds, and dozens of other animals      (via sciencedaily.com)     Original source 

Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
