Researchers from China, Leicester and Oxford have discovered a remarkable fossil which sheds new light on an important group of primitive sea creatures.

When it comes to producing more offspring, larger female hyenas outdo their smaller counterparts.

A University of Alberta-led research team has discovered that insects that bore into trees as long ago 90 million years, or as recently as last summer, leave a calling card that's rich with information.

When it comes to survival of the fittest, it's sometimes better to be an adaptable tortoise than a fitness-oriented hare, a Michigan State University evolutionary biologist says.

One of the blind spots in forensic science, particularly in identifying unknown remains, is the inability of experts to determine how much an individual weighed based on his or her skeleton. New research from North Carolina State University moves us closer to solving this problem by giving forensic experts valuable insight into what the shape of the femur can tell us about the weight of a person

A robust new phylogenetic tree resolves many long-standing issues in primate taxonomy. The genomes of living primates harbor remarkable differences in diversity and provide an intriguing context for interpreting human evolution.

Few specimens inspire greater thrills among fossil collectors than a complete trilobite. These ancient arthropods – relatives of lobsters, spiders and insects – went extinct more than 250 million years ago, but are sometimes found in beautifully preserved condition.

Its head looks like a turkey, its body resembles a chicken – now scientists can explain why one of the poultry world's most curious specimens has developed such a distinctive look in next week's issue of the online, open access journal PLoS Biology.. The Transylvanian naked neck chicken – once dubbed a Churkey or a Turken because of its hybrid appearance – has developed its defining feature

The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals.

Calling it the "new periodic table for flies," researchers at North Carolina State University and collaborators across the globe have mapped the evolutionary history of flies, providing a framework for further comparative studies on the insects that comprise more than 10 percent of all life on Earth.
