Hmm...Just now on my way past our "Stern Physics Laboratory" here at Rutgers, within the space of 30 seconds I found one 4- and two 5-leaved clovers. This got me to thinking about how once somebody told me that such mutations (?) were evidence of impurities in the environment, perhaps radiation. Is this true? I know that we can conclude a lot about the environment from studying animal populations. Is there any evidence that a layman can recognize (like these clovers perhaps) for environmental disturbances? Musingly, Lorien Pratt pratt@paul.rutgers.edu

Mutations might be caused by mutagens or other chemicals which would
damage a cell's genetic information. But things like cosmic rays,
background radiation, etc. could have the same effect, as could some
random fluke of chemical bonding during mitosis.
Some scientists have some pretty weird sounding theories about
"evolutionary leaps", etc. which I don't really subscribe to.
On the other hand, I think it probably has something to do with
Reaganomics, or maybe Albanian Maoism/Stalinism is to blame.

The existence of multiple 4-leafed clovers may mean that at one time there was a single 4-leafed clover in that spot, and it reproduced. I once found a patch with literally hundreds of four and five leaf clovers in a few square meters. If, however, you find a bunch of four-leaf clovers, and a two headed dog, and a giant ant, and a fire breathing dinosaur, all in the same place, worry.

My dad grew up on a farm in Maryland (c. 1940) where he says he used to find handfuls of four-leafed clovers. Given the time, I don't think it was due to human tampering. -- - Paul Martenis Cambridge, MA

Sort of like an extra half foot growing out the inside of the paw. She had 3 kittens there, 2 tigerstriped ones and a white one. The white kitten (only) also had 7 toes on each foot in precisely the same manner. Another tragic story of an unwed mother in the inner city. > - Paul Martenis -- Richard J.

Polydactyly (many (too many) "fingers") is a common "deformity" among some breeds of cat. Sorry, don't know which breed. In fact, it's not all that uncommon among humans either. -- These opinions are solely mine and in no way reflect those of my employer. John M.
