‘Red Effect’ Sparks Interest in Female Monkeys

Recent studies showed that the color red tends increase our attraction toward others, feelings of jealousy, and even reaction times. Now, new research shows that female monkeys also respond to the color red, suggesting that biology, rather than our culture, may play the fundamental role in our “red” reactions.

New U.Va. Study Upends Current Theories of How Mitochondria Began

Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants – and first acted as energy parasites in those cells before becoming beneficial, according to a new University of Virginia study.

Study Finds Crocodiles are Sophisticated Hunters

Vladimir Dinets, a research assistant professor in UT's Department of Psychology, has found that crocodiles work as a team to hunt their prey. His research tapped into the power of social media to document such behavior.

Spiders: Survival of the Fittest Group

Researchers have uncovered the first-ever field-based evidence for a biological mechanism called 'group selection' contributing to local adaptation in natural populations. Evolutionary theorists have been debating the existence and power of group selection for decades. Now two scientists have observed it in the wild -- as they report in the journal Nature.

Genetic Secrets of the Monarch Butterfly Revealed

JCdR3.jpg

Sequencing the genomes of monarch butterflies from around the world, scientists have made surprising insights into the insect’s genetics. They identified a single gene that appears central to migration – a behavior generally regarded as complex – and another that controls pigmentation, as well as shed light on the evolutionary origins of the monarch.

Tooth Serves as Evidence of 220 Million-Year-Old Attack

At the beginning of the age of dinosaurs, gigantic reptiles—distant relatives of modern crocodiles—ruled the earth. Some lived on land and others in water and it was thought they didn't much interact. But a tooth found by a University of Tennessee, Knoxville, researcher in the thigh of one of these ancient animals is challenging this belief.

Dinosaur Family Tree Gives Fresh Insight Into Rapid Rise of Birds

DinoBirdFig1credit_JasonBrougham.jpg

The study shows that the familiar anatomical features of birds – such as feathers, wings and wishbones – all first evolved piecemeal in their dinosaur ancestors over tens of millions of years. However, once a fully functioning bird body shape was complete, an evolutionary explosion began, causing a rapid increase in the rate at which birds evolved. This led eventually to the thousands of avian species that we know today.
