Bacteria and microbes would have been the first living things to move, and thus in a sense, the first organisms to be able to to dance on planet Earth. I’m attempting some microbiological choreography. In the first instance, can I persuade microbes to move with purpose and in a coordinated manner. The answer seems to be yes. It’s more like a flash mob, rather than an elegant ballet at present, but in the videos above Euglena gracilis has moved in a deliberate manner to a source of stimulus which results in a seething mass of mircobial cells and areas distil to the stimulus being far less populated. It’s easy to see how the complex multicellular behaviour that we see in plants might have arisen.
