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

Researchers recently discovered that the sea lamprey, a modern representative of ancient jawless vertebrates, fights invading pathogens by generating up to 100 trillion unique receptors. These ...

It may be a bias left over from the long time I've spent studying it, but the development of the vertebrate spinal column has always struck me as elegant. Two signaling centers on the top and bottom ...

The hypothalamus is involved during the coordination of neuroendocrine functions in vertebrates and their evolutionary origin can be described using integrated transcriptome or connectome brain maps ...

Humans have a ''disproportionately huge effect'' on the other species of vertebrates that share Earth's surface with us, causing more than 25 percent of the deaths among an array of species all over ...

Those of you who took high school biology may remember the lancelet, also known as the amphioxus. Its simplified body plan is notable for containing a number of features that it shares in common with ...

Vertebrates are distinguished by complex structures, particularly their head, which evolved for active feeding. In an article published in Nature Communications, scientists used the amphioxus, a close ...

This article predates Brown Brothers Media’s ownership of Science Blog and has not been reviewed under our current editorial process. It is preserved as part of the publication’s archive. One of just ...

While insects provide an essential food source for many vertebrate species, they're more than just a protein-laden snack.

How many fossils does it take to accurately train an image-based AI algorithm? According to a new study co-authored by Bruce MacFadden, UF Distinguished Professor Emeritus and retired curator of ...

Add Yahoo as a preferred source to see more of our stories on Google. Run an insect trap through a German nature reserve today and it will catch a fraction of the insects it would have trapped in 1989 ...

A fish that lives in rain puddles has beaten its own record for the fastest known sexual maturity among vertebrates. Some other vertebrates come close, but they take shortcuts, says coauthor Martin ...
