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 ...

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 ...

Deep within the dense foliage of Papua New Guinea lives the world’s smallest vertebrate. Meet Paedophryne amauensis, a ...

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, ...

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 ...

Direct survival benefits in larger groups rather than kin-selected indirect fitness primarily drive the evolution of division of labor in cooperatively breeding vertebrates, particularly under harsh ...

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 ...

Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the ...

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 ...

I first read Lulu Miller’s Why Fish Don’t Exist in 2024. Interspersed with her personal exploration of finding purpose, ...
