> Here's a suggestion (you are allowed to yawn): that innovation is caused by experimentation between cells/cell communities, and once a combination turns out to be functional and advantageous, further experimentation follows ... not by random mutation but by intercellular cooperation.-You cannot compartmentilize living organisms. Cells do not experiment among themselves. Change must be initiated in the genome perhaps using epigenetic signals from the somatic cells. Don't imagine eye cells telling each other what to do.
