🌊🌟 Meet the oldest living creature on Earth: the ctenophore, a jellyfish-like animal that emerged 700 million years ago. A new study in Nature reveals that ctenophores are the closest relatives of the first animals, and share a common ancestor with humans. #ctenophore #animal #evolution https://www.thebrighterside.news/post/scientists-discover-the-oldest-living-creature-on-earth-from-700-million-years-ago

Time for some truly wild biology.

Santiago Ramón y Cajal shared the 1906 Nobel Prize with Camillo Golgi for their work in neuroanatomy. Cajal proposed that nervous systems were composed of disjunction neurons, while Golgi argued that a nervous system comprised a synticium of fused cells.

Cajal was vindicated in the 1950s by advances in microscopy, but as with so many things in biology, both explanations were right in a way.
