For readers needing a review of previous developments, here are the preliminary description, and
initial condition. In those circumstances, with the effect of a single resource pattern, we have seen that a set of critters can grow in prosperity if, after the resource pattern has been dropped into their world, these critters follow certain rules as they choose how to act. We see this in the top of the picture below. There we see a large supply of water on the left and a large supply of sugar on the right (a resource pattern). Critters can thrive if they form a line between water and sugar, following rules to move excess water to the right and excess sugar to the left.
|A second resource pattern appears, in the bottom half of the tabletop above|
Now we have added a second resource pattern in the bottom half of the picture above. In most respects this second pattern developed just like the first resource pattern. That is:
- It appeared in a world in which a small population of critters already lived. Those critters lived near the edge of starvation as hunter-gatherers.
- After the resource pattern appeared, critters in that vicinity somehow discovered how to exploit the pattern and live better. By using their ability to pick up a resource, carry it a distance, and then set it down again, and by following rules about when and how to use this ability, they discovered a prosperous style of life. Their numbers increased dramatically in a line of trade between the water and sugar.
You should notice that both of these resource patterns exist in the same model world. Both resource patterns, once deposited, start to affect the lives of critters who were already living as hunter-gatherers in that region. But I have left a considerable distance between the two resource patterns in order to make it seem unlikely that critters would develop a line of trade between the two. We will assume for the time being that critters do not discover and exploit the possibility of trading between the resource patterns.
As such we notice an implication of distance in this model: the farther it is between a supply of water and a supply of sugar the less likely it is that critters will discover and employ rules that will enable them to cooperatively exploit the pattern presented by these two resources. Distance equates to difficulty for the critters.
We have two communities of critters who thrive by following rules, but the rules in one differ from the rules in the other. If somehow a critter found its way from one community to the other and then tried to become a productive member in the new community by following the rules which it had learned in its original community, it would fail in this effort. For example, suppose a critter that has learned to carry sugar to the left (in the upper resource pattern in the picture above) somehow finds itself in the other line of trade (in the lower resource pattern in the picture above) where physical reality requires that sugar be moved up, not left. This critter's effort to be a good citizen by following the rules it has learned will introduce waste, not help, into the new community.
Where critters discover rules which enable those critters to live better, those rules are dictated by the physical realities of the critters' nearby environments. Each new resource pattern may possibly introduce a requirement for a new set of rules. So even though we might think of our critters as constituting a single biological species, our critters must be capable of conforming to various sets of behavioral rules, rules as dictated by physical circumstances beyond the control of any of the critters.
As you must have guessed, I intend this modeling with critters to suggest explanations for some of our human experiences, as we will be seeing.
