An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: how the ventral nerve cord, a key component of the central nervous system, evolved in ecdysozoan ...

New research from the Layden Lab at Lehigh has demonstrated that the gene mechanisms at work during neurogenesis in the brain actually predate the evolutionary development of the central nervous ...

Some very diverse neurological systems have evolved in animals, like those carried by cephalopods, compared to those found in humans. But scientists have now found an interesting commonality: many ...

For over half a billion years, evolution has sculpted the nervous systems of bilaterian animals, equipping them with remarkable capabilities to process information, coordinate movements, and respond ...

Many people are familiar with oncogenes - genes long known to be involved in cancers in humans, such as the gene "Src." What's less widely understood is that oncogenes didn't evolve just to cause ...

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

Researchers at Karolinska Institutet have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have ...
