More about how evolution works: multicellularity (Evolution)

DAVID: Multicellularity is very complex and not an improvement on the easy livability present in bacteria. Again, why bother?

dhw: Endosymbiosis is a process that is beneficial to both organisms. Benefit = improvement in my book. As environments changed, new challenges and opportunities arose. The challenges required adaptation, but the opportunities enabled improvement. I’m surprised that you think “livability” is the only criterion for improvement.

'Opportunities enabled improvement' is a strange phrase. 'Challanges required adaptation' is correct. It demands improvement or extinction. Bacteria weren't challenged. They solve all problems and survive, need no improvement. Why multicellularity? Can't get to us any other way. Today's bush of life is exceedingly complex. Advancing evolution requires complexity beyond bacteria.
