Parthenogenesis, a form of asexual reproduction in which an egg develops in the absence of fertilisation, has traditionally been associated with invertebrates. However, recent discoveries have ...

Behavioral lateralization, the preferential use of one side of the body and its corresponding brain hemisphere, is a pervasive aspect of vertebrate neurobiology. This phenomenon, which manifests in ...

Add Yahoo as a preferred source to see more of our stories on Google. After an ancient extinction killed about 85% of marine species, survivors in isolated refuges helped jawed vertebrates diversify ...

Researchers have found that germ cells, which develop into eggs and sperm, drive sex-dependent differences in lifespan in vertebrates. Female and male germ cells increase and reduce lifespan, ...

A breakthrough in genetics reveals how spines first appeared, changing what we know about the evolution of complex species.

The field of gut microbiota research has undergone rapid expansion, uncovering the intricate relationship between microbial communities in the vertebrate ...

The water-to-land transition stands as one of the most significant events in vertebrate evolution, giving rise to the two major groups of living land vertebrates—amniotes and lissamphibians—which ...

The coelacanth is known as a “living fossil” because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light ...
