I came across article and i wanted to share it with you guys. http://www.nationalgeographic.com/deextinction/ Do you think it is a good idea to bring back extinct creatures like the Mammoth, Tasmanian Tiger, Wooly Rhinoceros, Pyrenean Ibex, Moa, Dodo, Giant Ground Sloth, Irish Elk and my favorite the Passenger Pigeon. Many of the creatures became extinct due to human actions like the Dodo and Moa. Some became extinct due to climate change or too overspecialization like the Marsupial Lion and the Cave Bear. A few interesting examples The Quagga is an extinct relative of the Zebra. The Great Auk was the North Pole version of the South Pole Penguin. Gigantopithecus, the larger Asian cousin of the gorilla Many of the creatures became extinct recently or in the last 100 000 years which means their DNA could still be recovered. Should we bring all the extinct creatures back or only those creatures that became extinct due to human actions ? How about creatures that became extinct due to a combination of human hunting and climate change like in the case of the Mammoth for example?
