A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, ...

Mammal evolution has been flipped on its head, according to new research that suggests marsupials are the more evolved mammals. By estimating how the common ancestor of mammals reproduced and ...

The evolution of some of the earliest complex animals on our planet may have been spurred on by other, simpler early animals. These simple marine animals first evolved around 560 million years ago and ...

Aside from rodents, primates like humans are the only mammals that have evolved nails on their thumbs as opposed to claws. However, the two lineages appear to have evolved this feature on their own, ...

The humble rodent “thumb” may not seem like an obvious window into evolution, but its keratinized tip – the unguis (hoof, claw, or nail) – turns out to reveal striking insights into rodent history and ...

Researchers reveal new insights into the complex evolutionary history behind the distinctive upright posture of modern placental and marsupial mammals, showing the transition was surprisingly complex ...

Rodents in Chicago have been adapting to an increasingly urban environment over the past century, a new study has shown. Evolution generally entails seeing small changes passed down over generations, ...

Evolution is often perceived as an incredibly slow, natural process driven by environmental pressures over millennia. That characterization certainly holds true, but humans have also repeatedly ...
