Sponges lack muscles and neurons. Yet, they make coordinated movements. Scientists at EMBL Heidelberg have discovered that sponge movement is controlled by an ancient ‘relaxant-inflammatory’ response that is also present in vertebrate blood vessels. The findings shed light on sponge physiology…

What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don’t have brains, what is the role of these? EMBL scientists imaged the sponge digestive chamber to find out.

Our cerebral cortex, or pallium, is a big part of what makes us human: art, literature and science would not exist had this most fascinating part of our brain not emerged in some less intelligent ancestor in prehistoric times. But when did this occur and what were these ancestors? Unexpectedly,…

The last ancestor we shared with worms, which roamed the seas around 600 million years ago, may already have had a sophisticated brain that released hormones into the blood and was connected to various sensory organs. The evidence comes not from a newly found fossil but from the study of microRNAs…
