This discovery of bacteria that combine together to form electric cables may suggest that there are mechanistic explanations of the development of multicellularity. > > http://blogs.discovermagazine.com/notrocketscience/2012/10/24/bacteria-living-electric-... I mentioned this phenomenon on Oct. 25th 16:20. My thought was this might have been an early attempt at very elemental nerve tissue, another evidence of convegence, a la' Simon Conway Morris. -What I don't understand is your comment that this is mechanistic or even an attempt at multicellularity. I didn't include it in this subject. But is nice to have you back, even if it is now and then.
