A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology .

The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic ...

Generation over generation, catch after catch, fishing changes fish evolution. This phenomenon, called fisheries-induced evolution, is well documented, though it impacts the myriad species of fish ...

D scans of ancient lungfish jaws reveal how early fish evolved to eat differently - offering fresh insight into vertebrate ...

By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.

Coral reefs are home to a spectacular variety of fish. A new study by biologists at the University of California, Davis, shows that much of this diversity is driven by a relatively recent innovation ...

Why did humans evolve to blink? To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water.

The Royal Swedish Academy of Sciences has awarded the Canadian evolutionary biologist Dolph Schluter the prestigious Crafoord Prize for his work on the mechanics of evolution, which has ...

Fish evolution is so strange that it's given us species that can count, change color by "seeing" with its skin and even fish that can "sing." But sea robins in the family Triglidae are some of the ...

Scientists in Australia have unearthed beautifully preserved fossilized hearts and other internal organs of ancient armored fish in a discovery that provides insight into the evolution of the ...
