Cyril Dean DarlingtonDied 26 Mar 1981 at age 77 (born 19 Dec 1903). British biologist whose research on chromosomes influenced the basic concepts of the hereditary mechanisms underlying the evolution of sexually reproducing species. He elucidated the behaviour of chromosomes during the formation of gametes (meiosis). Knowing that Thomas Hunt Morgan had shown that portions of homologous chromosomes cross over (are exchanged), Darlington recognized that this applied to evolution. He formulated a theory of evolution in which the inherited characteristics of the next generation are variable, determined by this crossing over mechanism. |
The Skin Graft
A married couple was in a terrible accident where the man's face was severely burned. The doctor told the husband that they couldn't graft any skin from his body because he was too skinny. So the wife offered to donate some of her own skin.
However, the only skin on her body that the doctor felt was suitable would have to come from her buttocks.
The husband and wife agreed that they would tell no one about where the skin came from, and they 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 man's new face. He looked more handsome than he ever had before! All his friends and relatives just went on and on about his youthful beauty!
One day, he was alone with his wife, and he was overcome with emotion at her sacrifice. He said, "Dear, I just want to thank you for everything you did for me. How can I possibly repay you?"
"My darling," she replied, "I get all the thanks I need every time I see your mother kiss you on the cheeks.
