### Golfing with ...

Three gentlemen are golfing one sunny day. They come to a difficult par with a water trap just after the tee. The first golfer proceeds to hit his ball right into the water. To retrieve it, he simply approaches the body of water and extends his golf club. The water parts, he takes his next shot and it lands on the green. The second golfer hits his ball towards the water, but rather than sink, the ball floats on top of the water. The golfer nonchalantly walks across the water and hits the ball onto the green.

The third golfer hits his the ball directly into the water, where it quickly starts to sink. As the ball sinks, a fish grabs the ball in its mouth. At that very moment, a hawk plucks the fish out of the water and begins to carry it aloft. As the bird soars higher, a bolt of lightning startles the bird, which then drops the fish into a nearby tree. When the fish hits a branch of the tree, the ball pops out, rolls down the trunk of the tree, across the green and right into the hole...

## Herbert CopelandBorn 21 May 1902; died 15 Oct 1968 at age 66.Herbert Faulkner Copeland was an American biologist who delineated four biological kingdoms, instead of just two for plants and animals. A decade after Darwin's Origin of Species, Ernst Haekel had proposed (1866) adding a kingdom, Protista, for microorganisms, but it wasn't accepted. Copeland further discriminated among the microorganisms in a paper in 1938, splitting them into two kingdoms: Monera and Protista. Copeland identified Monera as organisms without nuclei, and Protista as being largely unicellular, with nuclei. By 1956, he published a book,The Classification of Lower Organisms, still trying “to pursuade the community of biologists” to adopt these four kingdoms. Change came slowly, and continues beyond Copeland's ideas to now five or six. He was the son of botanist Edwin B. Copeland, from whom he learned the principles of classification.« |
