any of you guys read the lastest issue of scientific american? theres an article on a proposed idea to reintroduce animals from the pleistocene to the wild of north america. of course many of these species have long gone extinct, but some have close relatives living elsewhere on the globe. the idea, is that by reintroducing megafauna, north americas ecosytems will become more 'complete' and healthier than they have been for the last 50,000 years. bactrain camels, mongolian horses, guanacos and even lions and cheetah will no doubt be able to adapt reasonably well to the temperate conditions (so long as they keep reasonably far south) but what of the poor asian elephants that are proxies for mammoths? there's a guy in the UK who plans to do something similar albeit with much more recently exctinct species, such as bears and wolves, that still exist in mainland europe. personally, whilst i well and truly understand the science behind it - i can't see such a venture ever developing much beyond a jurassic park type zoo where some of the animals eat eachother - no doubt by the time the elephants start growing extra fur, they will have cloned mammoths anyway. still you can't say it wouldn't be fascinating to see how the animals adapted, if at all..... whats your thoughts?
