Two old women were sitting on a bench waiting for their bus. The buses were running late, and a lot of time passed. Finally, one woman turned to the other and said, "You know, I've been sitting here so long, my butt fell asleep!'.
The other woman turned to her and said "I know! I heard it snoring!"
Clarence E. McClungBorn 5 Apr 1870; died 17 Jan 1946 at age 75.Clarence Erwin McClung was an American geneticist and paleontologist who discovered the role of chromosomes in sex determination in a species of grasshopper. In a key paper, he reported that sperm exist in two forms, each with a different chromosome configuration. Thus, he was one of the first (1901) to deduce that chromosomes determine the sex of offspring. McClung also studied how the behaviour of chromosomes in the sex cells of different organisms affects their heredity. His theory was one of many that inspired scientists to pursue investigations such as the Human Genome Project, an attempt to map the structure and location of all human genes. He also published on Cretaceous fishes.[This birth date given in ADB. However, EB states 6 April 1870.] |
