Multicellular organisms without a nervous system behave like a swarm, finds study
Partial cross-section of T. adhaerens. The animal consists of three layers of cells: a dorsal and ventral epithelium layer, with an inner layer of fiber cells. The dorsal and ventral cells are ciliated, with the ventral cilia providing propulsive force for crawling along surfaces, the animal’s primary form of locomotion. Not shown are other specialized cells, such as digestive and crystal cells, that are not directly responsible for movement. Credit: Proceedings of the National Academy of Sciences (2023). DOI:…
