Scientists once thought that humans must have 2 million genes to account for all our complexity. But since sequencing the human genome, researchers have learned that humans only have about 19,000 to ...

(PhysOrg.com) -- People experience the world through five senses but sharks, paddlefishes and certain other aquatic vertebrates have a sixth sense: They can detect weak electrical fields in the water ...

Scientists have generated the genome assemblies of two hidden-neck turtles, unpublished until now. The results, which revealed a new three-dimensional structure of the genome within the phylogenetic ...

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 ...

A half-billion years ago, vertebrates lacked the ability to chew their food. They did not have jaws. Instead, their heads consisted of a flexible, fused basket of cartilage. A half-billion years ago, ...

Because we’re a member of the group, it’s easy to see vertebrates as the pinnacle of evolution, a group capable of producing bats, birds, and giant whales in addition to ourselves. But when they first ...

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 findings suggest that the appearance of the vertebrate head skeleton ‘did not depend on evolution of a new skeletal tissue, as is commonly thought, but on the spread of this tissue throughout the ...

The ancestor of all vertebrates, including fish, reptiles and humans was a big mouth but apparently had no anus. The microscopic creature named Saccorhytus, after the sack-like features created by its ...

Learn how a second pair of eyes helped this 518-million-year-old fish evade predators. Spiders have eight eyes, bees have five, and boxed jellyfish have 24 — but these are the exceptions. The vast ...
