Little Tim was in the garden filling in a hole when his neighbor peered over the fence.
Interested in what the cheeky-faced youngster was up to, he politely asked, "What are you up to there, Tim?"
"My goldfish died," replied Tim tearfully, without looking up, "and I've just buried him."
The neighbor was concerned, "That's an awfully big hole for a goldfish, isn't it?"
Tim patted down the last heap of earth then replied, "That's because he's inside your stupid cat."
Eric F. WieschausBorn 8 Jun 1947.American developmental biologist who shared the 1995 Nobel Prize for Physiology or Medicine, with geneticists Edward B. Lewis and Christiane Nüsslein-Volhard, for discovering the genetic controls of early embryonic development. Wieschaus worked together with Nüsslein-Volhard examining mutations in 40,000 fruit fly families. They discovered (1980) that about 5,000 of the fly's 20,000 genes are important to embryonic development and about 140 are essential. They formed the widely accepted model that three sets of genes control subdivision in the developing embryo: gap genes, pair-rule genes and segment-polarity genes. Their work helped scientists to better understand congenital mutations in other animals, including humans. |
