Oh get real. This close to Earth? Not likely.
It is interesting to note that for many years the true appearance of the Klingon race was unkown. The "Klingons" encountered along the Federation border with the Empire were a Klingon-human fusion, genetically created to make infiltration into Federation areas easier. The interception of the Amar transmission during the V'Ger incident revealed the true nature of the Imperial Klingon race and stunned Federation science. Before that time, no one had suspected that the Klingons were capable of such advanced genetic engineering, and a great deal of rethinking was done concerning the level of Klingon technology.
