Picking the Right Flower
Saturday, July 30th, 2005The buzz these days–if you read a just a little on evolution and particularly that theories of Darwin–is flowers.
The New York Times wrote about it; it also hit the Danish science media. Two American scientists (Jan Salick, the Missouri Botanical Garden, and Wayne Law, a graduate student, Washington University) have been researching on the snow lotus. It appears, that one species of the plant has been decreasing in height over time. Why is that?
The basic reasoning is, that people like to pick the taller, more beautiful flowers. So in areas where tourists (and other flower-picking people) are dense in number, the lower and/or more unattractive flowers will survive. In fact, the snow lotus lost 10 centimeters of its height over 100 years.
This is at the very essence of natural selection. Go to the NYT story I linked on top, to read more on this.
