Well, if this isn’t pretty solid proof of evolution and natural selection I don’t know what is.  Evolution, it takes thousands and thousands of years to make the smallest change, right?  Nope.  Apparently a change has been noticed in elephant tusk size in less that 150 years.  The theory is that elephants are getting smaller tusks as a survival mechanism due to poaching and Ivory harvesting.  Ya see….. mother nature DOES know what it’s doing 🙂

The average size of an African elephant’s tusks has gone down by half in the last century and a half. Indian elephants have undergone a similar tusk size reduction.

Experts believe the rapid evolution of the massive land mammals is due to poaching. Zoologists from Oxford University suggest that ivory poachers, who go for the largest males with the largest tusks, have caused the breeding behaviors of the animals to change rapidly in a short time.

The largest male African elephants have the largest tusks. These tusks are extremely important in elephant behavior, with the largest tusks usually resulting in more successful intimidation of smaller males or winning fights for female elephants. But when the largest animals are killed, it changes the breeding patterns of the animals. In short, without the largest males for competition, the smaller males with their smaller tusks will breed more successfully, and their offspring will have smaller tusks.
