Single cells undergo symmetry breaking and develop through cleavage divisions to produce a prolonged multicellular colony with distinct co-existing cell types.
Great research! I like symmetry breaking.

Indeed! I am sure they may have some genes, but, as you say, not the function. Here, I was more thinking that I could have been shown this video, told that it was an ichthyosporean and I would have believed it. Sometimes, we forget how widespread some cellular behaviours are.

Histone acetylation associated with genes is typically restricted to active gene TSSs, but in three distantly related species, an ichthyosporean, a chytrid fungus, and a flowering plant, we saw elevated levels of histone acetylation along the length of inactive or lowly expressed genes. 6/n
