Research solves a crucial piece in the puzzle of how vertebrates evolved
New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a spine - ...
From genetics alone, scientists can now predict how long any of myriad different creatures can live. The “lifespan clock” estimates vertebrate animals’ (those with a backbone) longevity — including ...
A set of jaws can invoke visions of deadly toothy sharks, and now scientists find the earliest fish with chops — the ancestors of all jawed creatures with backbones — were also armed with teeth, ...
(CNN) — Hundreds of millions of years ago, jawless fishes swam Earth’s seas, their brains protected on the outside by armored skin, and on the inside by plates made of cartilage. Scientists are still ...
Lab rats have rights. Before researchers in the United States can experiment on the animals, they need approval from committees that ensure they follow federal regulations for housing and handling the ...
