News — "The country that created the world's first cloned canine plans to put duplicated dogs on patrol to sniff out drugs and explosives. The Korean Customs Service unveiled Thursday seven cloned Labrador retrievers being trained near Incheon International Airport, west of Seoul. The dogs were born five to six months ago after being separately cloned from a skilled drug-sniffing canine in active service."This may have money-saving, utilitarian purpose, but it also raises uneasy questions about the uncertain future of genetic engineering through cloning -- if it becomes too commercialized. Will unscrupulous companies try to sell cloned favorite pets?
