Good Micro-Evolution Post

Warm Fuzzy hits it out of the park. She has a very interesting post about phenotypic selection against tusks in African elephants. Elephants born with tusks are being poached, thus preventing them from passing on their tusk gene(s). Thus a gene (or set of genes), once rare, which prevents (or doesn't cause) elephants from growing tusks is becoming more prevalent.
The cause, of course, is poaching. This major problem is another in a series of problems that can be solved by American invasion and usurpation of foreign powers, who are doing an insufficient job at protecting the planet's very valuable resources.
