I've read a lot about plans for JWST and future space telescopes to look for biosignatures on exoplanets, but is there any observation any existing or planned telescope could ever make that would be incontrovertible evidence of life? Given that the scientific consensus is "it's never aliens unless there's no other explanation, and even then it's not aliens", I just find it hard to imagine that anything short of directly photographing a live specimen (or a technosignature, but that is not what I'm talking about here) being accepted as proof of aliens. submitted by /u/D-Stecks [visit reddit ..read more

Thylacine (Marsupial) vs Jackal (Canid) 3. Hedgehog (Eulipotyphla) vs Tenrecs (Afrotherian) 4. Bat (Mammal) vs Eagle (Aves/Bird) evolving ability to flight Since it's likely that life elsewhere in the Universe (regardless of whether it's simple or complex) will follow Darwinian principles, I was wondering if Aliens would actually look the way they're depicted as in Movies and Pop culture and if there is ..read more
