Just yesterday I was pondering on the evolution of the Antarctic continent, and how it got to where it is today (prompted by the reports of recent ice samples that are over a million years old). Lo and behold today an article (from the journal ‘Science’) has come to my attention reporting on how ocean currents played a pivotal factor in the evolution of Antarctica. Apparently the meeting of Atlantic and Pacific ocean waters off the tip of South America (Cape Horn) helped change Antarctica from forest to ice cap. And what provided the basis for the above reports? Ancient fish teeth!
Fascinating stuff (if you’re passionate about Antarctica like us here at Discover the World, and have crossed the infamous Drake enroute to the Antarctic Peninsula)!
