If at an early stage in his evolution it was useful for an individual to be able to adapt to a language - using community, i.e., to learn language as fast as possible, selection for this capacity might well have brought about a genetic assimilation of at least the bases for what had originally been only a learned adaptive response.

Thus, the natural selection of adaptive species in biological evolution may be looked upon as an internalized teleology, since there is no «conscious» (or self - directed) attempt to choose «desirable traits» on the part of mutating organisms.

Thus, biological evolution appears to be associated with a final causation or teleology — the reciprocal maintenance and proliferation of adaptive species over the phylogenetic scale in an evolving and stable physical universe.

Evolution is in essence weeding out less adaptive traits via death (or lack of breeding).

Evolution and economics are not just analogous to each other, but they are actually two forms of a larger phenomenon called complex adaptive systems, in which individual elements, parts or agents interact, then process information and adapt their behavior to changing conditions.

And what we did is, in order to figure all this out, sort of trace the path of evolution, we did a whole bunch of sort of, swapping experiments, where we swappedGAL1 for GAL3and we swapped the ancestral protein type of protein in for GAL1or for GAL3, and we even swapped the GAL1and GAL3in for the ancestral protein, in another yeast that didn't have the duplication take place; and from this whole series of experiments, we really expected to find out pretty much how the proteins have changed; and the surprise was that most of [the] adaptive change that had taken place wasn't in the protein, it was in how the two genes were regulated.
