The earliest known vertebrates had four eyes—and they worked a lot like ours do, new research suggests
Many spine-bearing creatures, or vertebrates, have a curious bit of tissue deep in their brains called the pineal gland. It ...
About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, and shallow seas shrank fast.
Scientists have uncovered an unexpected genetic shift that may explain how animals with backbones first emerged and became so diverse.
New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a ...
Scientists have uncovered a surprising genetic shift that may explain how animals with backbones—from fish and frogs to ...
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 ...
Scarce evidence indicates that key evolutionary steps for jawed vertebrates occurred during or before the Silurian period, 444 million to 419 million years ago. Fossil finds pull back the curtain on ...
Every mammal, every fish, every vertebrate (creatures that have a spine) has two eyes. It’s been that way for millions and ...
Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...
Life on our home planet dates back to hundreds of millions of years before the arrival of the dinosaurs. Among the most ...
Researchers have elucidated the evolutionary origins of placodes and neural crests, which are defining features of vertebrates, through lineage tracing and genetic analysis in Ciona intestinalis, a ...
