As we now know, #cilia beating requires the distributed action of #dynein motors along the filament... Amazingly, a mathematician predicted this doi.org/10.1242/jeb.... (1958) in @jexpbiol.bsky.social before the discovery of dynein! (A few years later Gibbons found it in the protist #tetrahymena)

My #scientific #Blogarticle linked below discusses aspects of options of more than 2 #sextypes in nature and within animals. An example of a #ciliate with 7 different #sexes is presented with new #scientific #findings by researchers.
