An Asynchronous Parallel Evolution Strategy

This work introduces a new asynchronous parallel self-adaptive evolution strategy. An asynchronous scheme is chosen because the load on the processors is usually unbalanced. The proposed algorithm is nonblocking leaving no processor idle at any given time. The motivation and theory for the algorithm is based on the author’s previous analysis of continuous evolution strategies [9] and the reduct...

Evolution of lactase persistence: an example of human niche construction.

Niche construction is the process by which organisms construct important components of their local environment in ways that introduce novel selection pressures. Lactase persistence is one of the clearest examples of niche construction in humans. Lactase is the enzyme responsible for the digestion of the milk sugar lactose and its production decreases after the weaning phase in most mammals, inc...

Gene amplification: an example of accelerated evolution in tumorigenic cells.

During selection for methotrexate resistance, tumorigenic CHEF/16 cells and derivatives from CHEF/16 tumors underwent amplification of the dihydrofolate reductase gene (DHFR) at accelerated rates compared with closely related nontumorigenic CHEF/18 cells. "Dot blot" analysis showed that the CHEF/16 cells contained many more copies of the DHFR gene than did the CHEF/18 cells, when assayed at sim...
