That's the problem we have with digging up fossils. We have samples we've obtained going back half a billion years (for the big stuff) from a broad area (surface of the Earth), so whatever we have at hand will appear to approach randomness.
We delude ourselves into thinking the consequence, today's biota, are actually the result of random rather than "directed" processes.
That was yesterday's prediction ~ and today we find a "directed" process right there in the mitochondria (where I really never expected we'd find it).
Who or what came up with the "process" is a question still to be answered, but the "process" exists.
All of evolutionary theory is turned on its head. Unfortunately the writer of the review seems to be still stuck in time ~ hence references to fitness, et al.
So, you denounce your own source of the post?
"We delude ourselves into thinking the consequence, today's biota, are actually the result of random rather than "directed" processes."
Evolution is not simply some random process. It is a "directed process". It has always been understood to be so. That's the whole point. It is natural selection that provides the direction.
All great points. Thanks for the reply!
