How harmful male genitalia can impact reproduction in other species
Male Callosobruchus chinensis seed beetles have spines on their genitalia, which increase their fertilization success but injure a female's reproductive tract—especially a female of a related species called Callosobruchus ...
Lizards are larger and retain heat longer in high-altitude habitats
University of Granada scientists confirm that ectotherms–like reptiles and amphibians–do follow "Bergmann's rule". The 19th-century naturalist posited thatanimals inhabiting colder climates have a larger body size. The ...
The devil is in the detail
Researchers have looked at a species of fish to help unravel one of the biggest mysteries in evolutionary biology.
Yo-yo weight fluctuation has little influence on the health of fruit flies
Regaining weight after weight loss is usually undesirable, but is this 'yo-yo effect' actually bad for your health? Scientists from Wageningen University recently investigated the influence of diet on the lifespan of fruit ...
Mosquitofish genital shape linked to presence of predators

Shorebirds prefer a good body to a large brain
In many animal species, males and females differ in terms of their brain size. The most common explanation is that these differences stem from sexual selection. But predictions are not always certain. A team of researchers ...
Fossil brain teaser: New study reveals patterns of dinosaur brain development
A new study conducted at the University of Bristol and published online today in the Journal of Evolutionary Biology sheds light on how the brain and inner ear developed in dinosaurs.
La Brea Tar Pit fossil research shows climate change drove evolution of Ice Age predators
Concerns about climate change and its impact on the world around us are growing daily. New scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting ...
Oceans apart: Study reveals insights into the evolution of languages
A new Journal of Evolutionary Biology study provides evidence that physical barriers formed by oceans can influence language diversification.
