It is hard to fathom that such a highly complex, hierarchical mechanism of information storage on a microscopic scale could come about purely by chance.
Explaining this sort of phenomenon by slight, successive modification, as Darwin envisaged, seems problematic.
“Incredible videos showing cellular movements during development of mouse embryo.”
“If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications…”
Even down to the level of molecules and genes, there doesn’t seem to be any physical reason for plants to grow “Golden Ratio” patterns.
