Scientists once thought that humans must have two million genes to account for all our complexity. But since sequencing the human genome, we've learned humans only have about 19,000 to 25,000 genes - ...
New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure found in multiple 518 million-year-old ...
The placoderms were a diverse group of ancient armoured fishes and it’s widely believed that they are ancestral to virtually all vertebrates alive today, including humans. Placoderms dominated aquatic ...
New 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 important episode ...
The neural crest is characterized by its origin in the CNS, its migratory behaviour and its ability to differentiate into many cell types (multipotency). Although all animals of the chordate phylum, ...
Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science ...
Humans tend to put our own intelligence on a pedestal. Our brains can do math, employ logic, explore abstractions and think critically. But we can’t claim a monopoly on thought. Among a variety of ...
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 ...
