In the multicellular soil bacterium Streptomyces coelicolor, some cells begin producing plenty of antibiotics after mutations delete huge chunks of their genomes. Now a pc mannequin has helped to substantiate that that is no accident however an developed mechanism for dividing labour amongst cells in a colony.

“With Streptomyces, everlasting differentiation occurs by breaking the genome,” says Enrico Sandro Colizzi on the College of Cambridge.

Whereas definitions range on what makes an organism multicellular, for a lot of biologists it isn’t merely about having plenty of cells, …
