The main idea of the two paragraph is using ancient DNA analysis to answer archaeological mystery.For example,coprolites may yield answers from the distant past,dodo birds are considered a close relative of the pigeon beacause of their DNA,a woolly mammoth’s genome from fragments of bone providing-at least in theory-that cloning one might be possible,and we also can know how closely Neanderthals were related to modern humans and if the two species interbred.Therefore,with the technique of DNA analysis progressing,we may know more about past and even do the least damage on objects,creatures,and environmen
