A married couple was in a terrible accident where the woman's face was severely burned. The doctor told the husband that they couldn't graft any skin from her body because she was too skinny. So the husband offered to donate some of his own skin.
However, the only skin on his body that the doctor felt was suitable would have to come from his buttocks. The husband and wife agreed that they would tell no one about where the skin came from, and requested that the doctor also honor their secret. After all, this was a very delicate matter.
After the surgery was completed, everyone was astounded at the woman's new beauty. She looked more beautiful than she ever had before! All her friends and relatives just went on and on about her youthful beauty!

Theodosius DobzhanskyDied 18 Dec 1975 at age 75 (born 25 Jan 1900). Ukrainian-American geneticist and evolutionist whose work had a major influence on 20th-century thought and research on genetics and evolutionary theory. He made the first significant synthesis of Charles Darwin's theory of evolution with Gregor Mendel's theory of genetics in his book Genetics and the Origin of Species (1937). From 1918 his research gave experimental evidence that genes could vary far more than geneticists had previously believed. Thus, successful species tend to have a wide variety of genes that, while redundant in its present environment, do provide a species as a whole with genetic diversity. Such diversity enables the species to adapt effectively to changes in the surrounding environment—the basis for modern evolutionary theory.
