Duplicate Genes Help Animals Resolve Sexual Conflict

University of Chicago Medical Center

Duplicate copies of a gene shared by male and female fruit flies have evolved to resolve competing demands between the sexes. New genetic analysis by researchers at the University of Chicago describes how these copies have evolved separate male- and female-specific functions that are crucial to reproduction and fertility.

Birds and Primates Share Brain Cell Types Linked to Intelligence

University of Chicago Medical Center

In a new study, published this week in the journal Current Biology, scientists from UChicago show that some neurons in bird brains form the same kind of circuitry and have the same molecular signature as cells that enable connectivity between different areas of the mammalian neocortex.

When It Comes to Extinction Risk, Body Size Matters

Santa Fe Institute

Models for extinction risk are necessarily simple. Most reduce complex ecological systems to a linear relationship between resource density and population growth—something that can be broadly applied to infer how much resource loss a species can survive.

Scientists Discover Oldest Known Modern Human Fossil Outside of Africa

Binghamton University, State University of New York

A large international research team, led by Israel Hershkovitz from Tel Aviv University and including Rolf Quam from Binghamton University, State University of New York, has discovered the earliest modern human fossil ever found outside of Africa. The finding suggests that modern humans left the continent at least 50,000 years earlier than previously thought.

Researchers Pose Revolutionary Theory on Horse Evolution

New York Institute of Technology

Scientists have long wondered how the horse evolved from an ancestor with five toes to the animal we know today. While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory that suggests remnants of all five toes are still present within the hooves of the horse.

Meet “Alesi,” a 13-Million-Year-Old Ancestor, at Rutgers Geology Museum This Weekend

Rutgers University-New Brunswick

About 13 million years ago, a distant ancestor of modern apes and humans suffered an untimely death on the arid landscape of northern Kenya. Last year, a Rutgers scientist helped bring its tiny skull to light, filling in a huge gap in the evolutionary record. And on Saturday, members of the public are invited to come face-to-skull with that ancestor, known as “Alesi,” at the Rutgers Geology Museum’s 50th annual Open House event. The museum stands on the College Avenue Campus of Rutgers University–New Brunswick. Admission is free.

A Survival Lesson From Bats – Eating Variety Keeps Species Multiplying

Stony Brook University

A new study reveals that omnivorous New World noctilionoid bats, those species with diets including both plant and animal materials, produce more new species in the long run than specialized vegetarian or insectivorous species.

What Species Is Most Fit for Life? All Have an Equal Chance, Scientists Say

SUNY College of Environmental Science and Forestry

There are more than 8 million species of living things on Earth, but none of them — from 100-foot blue whales to microscopic bacteria — has an advantage over the others in the universal struggle for existence. In a paper published Jan. 8 in the prestigious journal Nature Ecology & Evolution, scientists describe the dynamic that began with the origin of life on Earth 4 billion years ago.
