Bizarre Theories About Space Alien Procreation

Evolutionary biologist explains aliens might reproduce by cloning.Dr. Sarah OttoPurely asexual reproduction lacks long-term viability. Without genetic variation, any environmental change causes major problems.

Some Earth species, such asaphidsAphids clone themselves during plenty. They use sexual reproduction during scarcity, creating genetic variations for different survival methods.

Evolutionary biologist statesDr. Sarah OttoExtraterrestrials could be hermaphroditic. They would possess both male and female organs on one body. This lets them reproduce fast; no mate searching is needed.

Hermaphroditic reproduction helps stationary species, like plants more than animals. Slugs show this in animals on Earth.

Evolutionary biologist notes sexual reproduction isn't just male-female. Dr. Sarah OttoDr. Sarah Ottosays. Sometimes there are A, B, C, and D choices on the menu. While some species on earth follow this pattern (like the Norway lobster), usually only two partners engage in any given reproductive act. So as far as we can tell, an alien orgy would be more for fun than strictly procreation.Norway lobster, usually only two partners engage in any given reproductive act.

Gene swappingGene swapping is common on Earth, so it could apply to space. Not all gene swapping involves sex. Bacteria swap genes when they eat other bacteria because they areprokaryotes, meaning they lackmembrane-enclosed nuclei.

This makes scientists think alien reproduction depends on whether their cells have enclosed nuclei.

Many accounts describe aliens probing humans for genetic material.Whitley Strieber described an abduction experience by aliens, which he shared inNigel Watson'sUFO Investigations Manual.

Strieber entered an alien craft. A one-foot-long anal probe went into his body. When they took it out, he saw it was mechanical; he thought it was alive.

Many humans claim sex with aliens, either on ships or on Earth. Some claim they hadhybrid human-alien babiesSome humans call their alien sex encounters unconsenting and scary. Others say the sex with aliens was thebest they've ever had.
