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.

While biological evolution of adaptive species may have occurred through a series of localized internal (or non - purposive) teleologies, the concrescence or bringing together of physical and biological processes corresponds to both a globally internalized (non-purposive) and globally externalized (purposive) teleology of the observable universe.

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.

While we may designate natural selection of adaptive species as the efficient cause of biological evolution, its final cause may now be defined as the mutual preservation of all biological species on earth.

Rosowski Professor of Biology at the University of Nebraska who was not involved in the research.

The study, which combined genetic analysis with a 19 - year - long selection experiment, supports the idea that the mechanisms of adaptive evolution may be more predictable than previously suspected.

These results show how similar ecological contexts can result in the repeated evolution of highly adaptive strategies across species and regions.

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.

Objecting on both philosophical and empirical grounds, Fodor and Piattelli - Palmarini reject natural selection as the mechanism of adaptive evolution.

The concepts of contingency and entrenchment were well known to be present in adaptive evolution, but it came as a surprise to the researchers to find them under purifying selection.

«In addition, many of the high - frequency sequences span genes involved in the immune system, which is a frequent target of adaptive evolution.»

This is the first example of adaptive evolution triggered by interspecies introgression in domesticated animals, which gave us a clue that introgression event between divergent species may be an important resource for evolutionary adaptation and could largely facilitate this process.
