This study makes extensive assumptions about life on other planets being earthlike. Boy will we have egg on our face when the xenonauts land on earth with their breathing tanks full of carbon monoxide.
- andrewflnr 7y agoI'd be curious to see an outline of a metabolism based on CO. Can you build an analogue of hemoglobin that behaves nicely with CO?
- idlewords 7y agoWe wouldn't know how to build anything at that level of complexity. We can only study and modify molecules that evolution found here on earth, which severely limits our ability to imagine anything truly different.
- hoseja 7y agoWho says there has to be anything resembling hemoglobin? Or blood? All this xenobiology is so shortsighted.
- andrewflnr 7y agoCirculating fluids are super convenient for moving chemicals around. Plants use them, too. I would be very surprised if there wasn't at least an analogue for blood.
