It’s a fondly asserted belief within UFOlogy circles that aliens have instituted a cross-breeding program for the purpose of creating a race of alien-human hybrids.
Setting aside for the moment the numerous problems regarding stability of the resultant chromosome structures, as well as the potential mutations this sort of act would introduce into a global environment ill-prepared to handle such trauma, can somebody please tell me what intelligent lifeform would even consider mingling its DNA with that of an inferior species? Do aliens not understand evolution? Are they neo-creationists, or are they just fond of taking two steps back for every one step forward? Or, even more frightening on a level few people are willing to contemplate freely, are these aliens just Kansas Republicans borrowing a few chosen perspectives from the Church of Latter Day Saints? Aside from the wishful thinking of Hollywood, is it even possible for an entire species to commit suicide or bring about self-extinction without the cause and effect that alien-human hybrids would invariably represent?
