A man walked into work on Monday with two black eyes. His boss asked what happened.
The man said, "I was sitting behind a big woman at church. When we stood up to sing hymns, I noticed that her dress was caught in her crack, so I pulled it out. She turned around and punched me square in the eye."
"Where did you get the other shiner?" the boss asked.
"Well," the man said, "I figured she didn't want it out, so I pushed it back in."
Cyril Dean DarlingtonBorn 19 Dec 1903; died 26 Mar 1981 at age 77. 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. |
