California two-spot octopuses learned to track prey they could see only as a mirror reflection, then moved toward the actual ...

In a new study, researchers used a new live-imaging technique to watch neurons being created in squid embryos almost in real-time. They were then able to track those cells through the development of ...

Our skeleton is kind of strange. Most of it forms from the same tissue that makes things like our muscle and connective tissue. The exception is a big chunk of our face, like the jaws and nasal ...

IN the review of my book on the “Origin of Vertebrates,” which appeared in NATURE of May 13, the reviewer, discussing my theory that the vertebrate centra nervous system represents the conjoint ...

Ascidians, also known as sea squirts, are the evolutionary link between vertebrates and invertebrates, making them valuable subjects of biological studies. For the first time, researchers at Ruhr ...

RECENT research on the functions of the nervous system of man and other mammals, such as Head's clinical observations and Sherrington's experimental work, has revealed the fact, which had not been ...

Charles Darwin proposed that evolution is driven by gradual variations in organisms that have a survival advantage in a changing environment. But University of Maryland evolutionary biologist Karen ...
