Editing Genestealer (section)

== Later Editions ==
In later editions of [[Warhammer 40,000]], the Genestealers were revealed to be (or [[retcon]]ned into, depending on your point of view) vanguard organisms for the [[Tyranid]] Hive Fleets. They are capable of thinking for themselves and operating without the Hive Mind's leadership, a rare trait among Tyranids, although they are not synapse creatures. [[Space Hulk]]-era Genestealers were re-designated "Purestrain Genestealers," created by the Hive Fleets themselves.

Genestealers are sent to infest Space Hulks and spread among the stars. Their long tongues contain a barbed ovipositor; when they encounter sentient anthropoid, they [[Rape|use this ovipositor to inject a "seed" into the host's body]], combining the host species' genome with the greater Tyranid genome (hence the name Gene-stealer.) This is a method called the "Genestealer's Kiss," which is either a face-biting parody of a kiss or an injection under the ribcage. Fun fact, this biological process exists in real life under the name of "horizontal gene transfer", and is mostly used by bacteria to help other bacteria develop resistances to antibiotics, and more importantly is the main process involved in genetic engineering! More recently, the Genestealer Cult of the Twisted Helix has discovered how to extract this "seed" for use in contaminating food and medicine, allowing the Genestealer curse to spread to locations far removed from any actual Genestealer.
