The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

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 ...

A cheetah pouncing on a gazelle. A bear snatching a fish out of the water with its claws. And the most dangerous predator of them all? A human and their pet bird dancing to “Gangnam Style.” Scientists ...

New CU Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an ...

Scientists have long puzzled over the gap in the fossil record that would explain the evolution of invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, ...

The cranial anatomy of an extinct fish reveals an intermediate stage in the evolution of feeding systems in vertebrates, a study finds. During the transition from water to land, vertebrates shifted ...

A team of herpetologists at the Universidade Estadual de Santa Cruz just reported that a tiny frog found only in a hilltop forest in southern Bahia, Brazil, may be the smallest vertebrate in the world ...

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, ...

Global change is eroding life on earth at an unprecedented rate and scale. Species extinctions have accelerated over the last decades, with the concomitant loss of the functions and services they ...
