Another crazy thing is that it usually takes thousands of years for an animal to develop evolutionary changes like the elephant has done‚ but the elephant has done it in 150 years? Well‚ scientists call this rapid evolution and it is all due to one very common problem (Environmental News Network et.al 2008). What I was able to find out though was that this evolutionary change is actually helping them survive. How you may ask? Well‚ one problem in today’s world that
