In the animal kingdom, mating isn’t always about survival. From praying mantises to octopuses, some species die during or ...

Meet animals that grow for a lifetime, sometimes for centuries, and discover why dinosaurs did not, despite their huge size.

Find out which animals live the longest and what clues this gives us for potentially slowing down human aging.

A paper published by URI researchers reveals key mechanisms in speciation in corals. Critically threatened by climate change, a better understanding of coral biology will help efforts to conserve and ...

Research reveals how natural selection shaped the Bajau sea nomads’ spleens to boost oxygen delivery, helping them dive for ...

Evolution is slow, but with the right experimental set-up—and enough time to spare—you can watch nature do its methodical ...

For well over a century, Darwin’s theory of natural selection has served as biology’s grand unifying framework, explaining how species adapt and evolve through the differential replication of randomly ...

In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, ...

Male factors contribute to ∼50% of all infertility cases globally and are a major contributor to escalating use of ART. In most instances, sub-fertile men retain the ability to produce spermatozoa, ...

Long before DNA unraveled the double helix of life, scientists were already tinkering with its inheritance. The idea that traits could be passed from one generation to the next fascinated early ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
