Some big picture articles have already been cited by Christy early in this thread. What do you think of those two articles?
Also, please bear in mind that when a stochastic process occurs over millions of years, lots of details get lost. And biology is a stochastic process.
Describing an evolutionary history is not the same thing as describing an automobile assembly line because, in principle, everything above the quantum level can be explained in an automobile factory. This is not true of stochastic processes such as stock market indexes and biological evolution.
That you think an auto factory is a suitable analogy makes me wonder how deeply you understand biology.
Best,
Chris
EDIT: Another recent BioLogos thread has links to additional resources on the evolution of vision. I think you will find it illuminating, Craig.
