artificial selection

"Nature is an amazing chemist, and her repertoire now includes breaking bonds in siloxanes previously thought to evade attack by living organisms," says Frances Arnold, the Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry at Caltech and winner of the 2018 Nobel Prize in Chemistry for her pioneering work in directed evolution, a method for engineering enzymes and other proteins using the principles of artificial selection.

The proposal also states that “historically, some people have misused and/or applied the ideas of natural selection and artificial selection to justify genocide of various groups, such as Albinos in Africa or Jews in Europe.”

The team used a population of T. castaneum that had undergone artificial selection for death-feigning duration for more than 40 generations.

Each breed produces a winner, representing the best of what artificial selection can create from the descendants of wolves.

When animals are domesticated, as the dog was, their traits change; an artificial selection occurs over many generations, which, in the case of the dog, probably happened through unconscious selection bias among ancient humans and their canid hangers-on.
