Climate-Change Clues From the Turtles of Tropical Wyoming

View | Comment

Tropical turtle fossils discovered in Wyoming by University of Florida scientists reveal that when the earth got warmer, prehistoric turtles headed north. But if today’s turtles try the same technique to cope with warming habitats, they might run into trouble.

Fearless Birds and Shrinking Salmon: Is Urbanization Pushing Earth's Evolution to a Tipping Point?

View | Comment

That humans and our cities build affect the ecosystem and even drive some evolutionary change is already known. What's new is that these evolutionary changes are happening more quickly than previously thought, and have potential impacts on ecosystem function on a contemporary scale. Not in the distant future, that is -- but now.

Moths Shed Light on How to Fool Enemy Sonar

GAINESVILLE, Fla. --- It’s hard to hide from a bat: The camouflage and mimicry techniques that animals use to avoid becoming a meal aren’t much use against a predator using echolocation. But a new study shows that moths can outsmart sonar with a flick of their long tails.

Molecular Evidence for the Loss of Three Basic Tastes in Penguins

View | Comment

A University of Michigan-led study of penguin genetics has concluded that the flightless aquatic birds lost three of the five basic vertebrate tastes—sweet, bitter and the savory, meaty taste known as umami—more than 20 million years ago and never regained them.

A new Santa Fe Institute study by Paul Hooper and collaborators details the intergenerational food sharing in a society of Amazon forager-farmers and shows that differences in relative need determine contributions to children from parents, grandparents, and other kin.

Settling for 'Mr. Right Now' Better Than Waiting for 'Mr. Right'

View

Evolutionary researchers have determined that settling for “Mr. Okay” is a better evolutionary strategy than waiting for “Mr. Perfect.” When studying the evolution of risk aversion Michigan State University researchers found that it is in our nature – traced back to the earliest humans – to take the safe bet when stakes are high, such as whether or not we will mate.

Machine Learning Offers Insights into Evolution of Monkey Faces, Researchers Find

View | Comment

HighamFeb2015.jpg

Computers are able to use monkey facial patterns not only to correctly identify species, but also distinguish individuals within species, a team of scientists has found. Their findings, which rely on computer algorithms to identify guenon monkeys, suggest that machine learning can be a tool in studying evolution and help to identify the factors that have led to facial differentiation in monkey evolution.
