in a somewhat related story, I was on a beach in Costa Rica last week, watching some spider monkeys in a palm tree trying to whack open small nuts. Just then, an American family walked up the beach with two teenage boys. They didn't notice the monkeys I was watching. But one of the boys grabbed a coconut off the sand and became determined to break it open with a rock in front of his parents. So watching the monkeys and the boy simultaneously, I had the distinct feeling of how slowly evolutionary, let alone geological, processes actually move.

Haha, cool, that gave me a chuckle :)

Nice story.

But are you implying that we are somehow more evolved than the monkeys? Both the human and the monkey in the story have evolved for the same amount of time since our last common ancestor.

That argument always struck me as vacuous. Dump a barrel of ball bearings on the top of a craggy hill. Wait as they all bounce around, some getting stuck in local minima and some bouncing over obstacles and covering large distances.

Would you claim that they all traveled the same distance because they all traveled for the same amount of time?

Evolutionary space is very high dimension, which makes the argument that just projecting onto the (1d) time axis is misleading even stronger.

[hermitcrab]

I'm not sure more/less evolved is a meaningful concept in Darwinian terms. Organisms have a level of fitness for their environment. Perhaps you are talking about cultural evolution?

[nandomrumber]

Do not we humans and those monkeys largely share the same environment?

Which one is more numerous, less prone to natural forcings?

[tejtm]

frame of reference matters, from the center of the sun or galactic core they all most certainly moved the same distance in the same amount of time and it was much further than the hill was tall.

[MarkusQ]

Sure? What is the analog to this other frame of reference in the evolution case though? Or are you just stepping out of the analogy's applicability range to show that it can be pushed too far (which is of course true of an analogy)?

[tejtm]

A Molecular clock would be gravity in your model, when ever you called stop all your marbles would have experienced the same amount of gravitational force. That is the intent of "experienced the same amount of evolution" and similar.

Where I see the model flounder is; the hill provides the fitness context. You implied distance "means" more evolved, but for life it is all about making it to the next round, in your marble game how many of those furthest marbles will ever be found for the next round?

With life big changes are dangerous, you may find yourself improved out of options.
