there are a number of serious proposals to try to revive extinct species.Some animals on this list include: the woolly mammoth (an elephant-like creature that wandered the plains of siberia),the moa (a giant flightless bird from new zealand), the thylacine(also known as the tasmanian tiger because of the dark stripes down its back),and the bucaedo (a mountain goat form spain).These animals had very little in common and in most cases lived eras apart. The wooly mammoth,for example, died many thousands of years ago while the bucardo became extinct only around the year 2000.But all these species lived at the same time as humans, and humans have been largely responsible for their destruction. So it seems somehow fitting that we are now thinking of reviving them.
