In DNA, retrotransposons can move around and insert themselves into other parts of genomes with a kind of copy and paste mechanism. Most have lost this ability in humans, but they still make up a ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

The formation of a part of the human brain responsible for regulating vital functions is triggered in an identical way in the sea lamprey, a new study has found. The discovery suggests that we’re ...

A ‘one of a kind’ fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.

A fossil smaller than a human fingernail has revealed a complete ancient brain, turning a speck of stone into a detailed map ...

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, ...

Sea urchins, which seem to spend their lives idly attached to undersea rocks, were considered simple creatures without eyes, ...

Integrative analysis revealed that functional disruption of Opn5L impairs light-dependent swimming behavior. The molecular profile of these neurons partially overlaps with that of vertebrate brain ...

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling ...
