What are some theories you/other people have on the biology of kerbals?

[VictoryNeverFail]

Just wondering...

They're sentient plants.

When a mommy Kerbal and a daddy Kerbal love each other in that special  way in the confines of a MKS Tundra Colonization Module you get....  more Kerbals

They essentially live underground and are poliferous, and they do photosynthesis (hence the green color) as well. The green you see on Kerbin is not grass. 

[Kosmix1]

Apparently they are biologically immortal as they never die from age or disease.

[Popestar]

Lizards.

[sir rocket]

extremophiles (did I spell that right?) who evolved from tardigrades after earth was destroyed.

Biomimetic plankton.

I’ve seen a few different ideas around the forums about Kerbal biology (Kerbiology?) including that they reproduce by spores, hence the grey cloud that gets released when they *ahem* lithobrake a bit too enthusiastically, or that they can survive on photosynthesis alone but will atrophy mentally without eating (brain food taken to an extreme).

But if you’re talking Kerbiology, you have to mention @KSK’s theory that Kerbals are in a symbiotic relationship with semi-sapient contact-telepathic trees capable of large-scale biogeoengineering, and the entire space program is just a means to start an interplanetary tree-planting initiative.

It almost makes sense when you put it like that.
