Doesn't Natural Selection lead to Specified Complexity?

But the distribution of genes in the current generation is about which 'genes' survive ... isn't it?

But a sterile individual can still affect the gene distribution in the subsequent generation ... by potentially removing some individuals from contributing to the next generation.The dead thing is irrelevant in the model I was considering since if you are dead youe are, by definition, not IN the population.

Isn't behaviour (i.e. action) related to genetic makeup?The deceased are counted, since we are looking at an iteration over a number of generations.Perhaps it is more like a filter where we have something like:a[k] = a[k-1] + b.a[k-2] ....But the deceased are involved as they would account for 'activity' in previous iterations.

At any point in time, k, the genetic makeup of the population is an acculation of the results from the past .... which will include deceased individuals. So maybe I changed tack a bit there, but it's been a while since I even looked at what I was saying here.'Behaviour' is part of my environment ....The deceased are no longer part of the population at time k, but were at some point from k-1 .... k-n.
