Among the earliest known vertebrates some had 4 eyes, and it’s amazing what they’ve become
The preservation of fossils of some of the oldest known vertebrates is so impressive that palaeontologists can not only count their eyes, but determine how they worked. The findings demonstrate that ...
About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, ...
Ancient fossils reveal the oldest known vertebrates had four eyes. Remarkably preserved fossil specimens show they could see ...
A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving ...
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, ...
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 ...
AMES, Iowa – Scientists searching the most ancient corners of the genome of a reptile native to New Zealand found patterns that help explain how the genomes of all vertebrates took shape, according to ...
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 ...
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 ...
