Deep within tropical forests, sloths move at a pace that seems almost frozen in time. Their slow movements, low energy use, ...

Sloths are the slowest mammals on the planet, but living in dense jungles has made them notoriously difficult to study. For ...

Genes aren't just transferred from parents to their offspring. Nature has found other ways to pass on genetic information, ...

Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements. The technique revealed that modern ...

The E. affinis complex currently serves as a valuable model system for investigating evolutionary adaptation during habitat transitions, both during biological invasions and in response to climate ...

In contrast to cnidarians that host photosymbionts intracellularly, giant clams harbor symbionts extracellularly, within an elaborate network of tubules derived from the digestive system 19. The ...

New research is shaking up our understanding of evolution by revealing that some species may not evolve gradually at all. Instead, scientists discovered that certain marine worms experienced an ...

Most animals straightforwardly inherit their genetic material. DNA passes from parent to offspring, generation after ...

The sequencing of the genomes of a spider from the mainland (Dysdera catalonica, left) and one from the Canary Islands (Dysdera tilosensis, right) opens a new perspective for understanding how genome ...

Our genetic heritage is not a blueprint or an algorithm, as many biologists have imagined, but something else entirely.
