great quote about evolution

[87] "...Darwin's "laws" do not encapsulate the transformations of life in quite the same way that Newton's laws capture the motion of objects. They render evolution intelligible, but not predictable or reducible. That is, to understand the evolution of any single organism, the sparse outline provided by Darwin's model must be filled in with long passages of peculiarities-- details of the organism, its development, its mutations, its ecology, the events that befell its ancestors. Only then does the simple, universal model cast any light on any particular organism. And only when the laws serve to elucidate the organism does a study of the organism reveal the action and significance of the laws."

A Great Quote from Matt Ridley

The fuel on which science runs is ignorance. Science is like a hungry furnace that must be fed logs from the forests of ignorance that surround us. In the process, the clearing we call knowledge expands, but the more it expands, the longer its perimeter and the more ignorance comes into view.
