Evolution's motto: neccesity is the mother of invention

Evolutionary biologist Chris Thomas (above) takes a long view of the biological tumult being exerted by humans on the biosphere.  Chris argues that biological systems are incredibly resilient to change....even the profound changes we are causing.  From a scientific perspective he thinks this is just incredibly interesting to watch.  But he also thinks that maybe we need to take this dynamic resiliency more into account as we develop ways of negotiating our eponymous mass extinction.  Check out his interesting ideas here on this episode of Living on Earth: http://www.loe.org/shows/segments.html?programID=14-P13-00019&segmentID=6
