Bob was sitting at the table one morning, reading the paper after breakfast. He came across an article about a beautiful actress who was about to marry a football player known for his lack of IQ.
He turned to his wife and said, "I'll never understand why the biggest jerks get the most attractive wives."
She replied, "Why, thank you, Dear!"
Sewell WrightBorn 21 Dec 1889; died 3 Mar 1988 at age 98.American geneticist who was one of the founders of modern theoretical population genetics. He researched the effects of inbreeding and crossbreeding with guinea pigs, and later on the effects of gene action on inherited characteristics. He adopted statistical techniques to develop evolutionary theory. Wright is best known for his concept of genetic drift, called the Sewell Wright effect - that when small populations of a species are isolated, out of pure chance the few individuals who carry certain relatively rare genes may fail to transmit them. The genes may therefore disappear and their loss may lead to the emergence of new species, although natural selection has played no part in the process.« |
