The following excerpt is "experimental" in the sense that I'm not sure if I want to ultimately include the point I make. But it's a valid point, and since this is my blog i'll post it :)
One of my favorite illustrations of "intuitive scope" deals with time. Human experience with the passage of time maxes out at about 100 years; to understand what happens over longer periods, we have to read about it rather than experiencing it, and second-hand knowledge doesn’t give you the same “feel”. A friend of mine who is a young Earth creationist once exclaimed how ridiculous it is to think that evolution could have given rise to the biodiversity we see in the world today. I argued that she could only say it was “obviously” ridiculous if she had some intuitive understanding what can happen on evolutionary time-scales. The fact is that no human has a “feel” for evolutionary time scales - regardless of our religious affiliation (if any), we all have to rely on empirical methods to say anything substantive. If somebody who had been alive for 10 million years dismissed evolution out of hand, I would take serious note.
Imagine a race of intelligent insects living in a forest, whose lifespan is only 24 hours. Their society would evolve reckoning time by the day/night cycle. When they progressed to the point of having oral histories, they might preserve fireside tales about of “great rainy day” from last week, and ancient mythologies describing the last full moon. When their written histories became extensive enough to cover 100 generations (about the position our society is in now), a few historians might hypothesize that the world had gradually undergone a transition from summer to fall. The first ones who suggested it would probably be burned at the stake, but they would be vindicated. Around the same time somebody else would note the similarities between the saplings, old growth trees and fallen logs in the forest - they would propose the eerie idea that trees grow and die on time-scales even longer than the seasons.
Perhaps ironically, young earth creationists gives the power of natural selection a lot more credit than does evolutionary theory. They hold that, in the roughly 4500 years since the Great Flood, the family of Noah has expanded and diverged to include tall blonde Scandinavians from northern Europe, short dark-skinned Bushmen from southern Africa (who are one of the most genetically distinct groups in the world), and people of Asian descent. That’s a lot of change for 200 generations! Evolutionists say this divergence took about ten times that long, and that it started with a large population of humans that was already genetically diverse (and that borrowed additional genetic diversity from Neanderthals), rather than a single family.
