Study suggests adapting to life on land wasn't the biggest challenge facing fish coming ashore millions of years ago.

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

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 June 24 th in the open-access journal PLOS ...

Fish exhibit considerable biodiversity in genetics, morphology and behaviour that has been shaped by environmental factors such as habitat variation, climate fluctuations, and geological events. By ...

What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...

Deep-sea fish have adapted through two evolutionary pathways: ancient survivors and new immigrants. A key finding challenges the TMAO hypothesis, revealing a genetic mutation in the rtf1 gene that ...

Life reconstruction of Platysomus, with open mouth showing toothplate on the floor of the mouth supported by gill bones. ANN ARBOR—A University of Michigan researcher helped identify the earliest ...

Long before modern salmon ran Alaska’s rivers, their ancient relatives thrived alongside dinosaurs in the Cretaceous Arctic. Scientists have identified three new species from 73 million years ago, ...

Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn an ...

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 ...

Earth, rocks, evolution, and fish : background information to understanding fish evolution -- Glorified swimming worms : the first fishes : origins of chordates and the first vertebrates -- Jawless ...
