The resurrection of extinct species is definitely more feasible than interstellar travel and advances in DNA reading and writing technology have advanced a million fold in little more than half a dozen years. The speed of light is still the speed of light even though the bulk of Sci Fi writers simply ignore it. We'll certain see such things long before sending a probe to Barnard's star or travel back in time to observe our remote ancestors.
Harvard professor George Church, pioneer of the Human Genome Project and founder of half a dozen Biotech firms thinks the technology is just about here that enables us to facilitate the "de-extinction" of vanished species -- perhaps not creatures that died out over a million years ago -- you're not going to see a real Jurassic park any time soon unless it contains reverse engineered birds that sort of look like some Dinosaurs, but he thinks we're on the verge of being able to bring back the Neanderthalers.
He stops short of saying we ought to and of course it's illegal to clone humans in Europe and the US, but he thinks we might learn something important to our own future. Establishing a group of our long lost cousins and possible partial ancestors might show us that they were more intelligent, with their bigger brains or perhaps had some talents that we do not and might allow us an increase in human biodiversity.
"it's conceivable that their way of thinking could be beneficial" said Church to an interviewer from Der Spiegel.
Wayne LaPierre stated yesterday that a study should be initiated to determine the citizenship status of any non-Homo Sapiens clone born in the US or possessions so as to establish a Neanderthaler's right to keep and bear arms other than wooden spears. Several coaches and athletic associations have expressed interest in any such project, while Tea Party spokesmen have been rather unanimous in objecting to allowing such clones to take 'human' jobs as much as they would welcome them into the party ranks, despite their bigger brains.
Cloning humans, or even almost humans is illegal, sure, but America is waiting.
