I’ve often been watching some Discovery Channel documentary on the horrors that poaching can visit upon elephant populations in the wild, and thought to myself “I am so glad that we don’t support that sort of barbaric activity here.”
A species’ evolution has long been thought to take thousands of years to produce seemingly minor changes.
It appears that in at least one case, however, evolution is occurring at what seems like jet speed. In the last 150 years, the world’s elephant population has evolved much smaller tusks.
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.
