We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, a

Being nursed by a single parent could be an evolutionary strategy to curb the spread of harmful microbes in mammals, according to a novel theory developed by mathematicians.

It is widely accepted that biological interactions are stronger or more important in generating and maintaining biodiversity in the tropics than in temperate regions. However, this hypothesis has not been fully tested in ecology and evolutionary biology.

Ammonites were not in decline before their extinction, scientists have found.

Maternal immunity refers to the immunity transferred across the placenta, colostrum, milk or eggs from mother to offspring. It plays a key role in protecting the vulnerable offspring against pathogenic attacks, and is present in nearly all vertebrates and

A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet.

An international team of researchers, led by the Leibniz Institute of Virology (LIV), have uncovered crucial details on how herpesviruses exit the cell nucleus without compromising the integrity of the nuclear envelope. Herpesvirus infections are widespre

The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery

For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new creature burst into existence: the multicellular organism.

Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for anti-bacterial control measures in

The deep sea is the largest living space on Earth, but many of the animals and habitats far beneath the ocean's surface remain shrouded in mystery. MBARI's advanced underwater robots, including remotely operated vehicles (ROVs), are helping survey life

In a study appearing in Nature, an international team of researchers led by the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identify
