Why ET's genetic code could be just like ours
- Semiapies 18y agoThe possible similarity/dissimilarity of alien life to earth life (and hypothetical intelligent aliens to humans) keeps going back and forth. On one end, you see Hal Clement-esque ideas about critters with wild biochemistries and/or strange morphologies, on the other you see thoughts about a common biochemistry and/or convergently-evolved humanoids. Personally, I'd prefer to see this addressed by comparing sample groups. :)
