Eyes evolved on Earth at least 50 times—octopus eyes basically ours—so aliens might look uncannily familiar thanks to convergent evolution. Think crabby body plans, infrared vision under red dwarfs, or low-slung heavy‑gravity pancakes, while the James Webb Space Telescope scans exoplanet atmospheres for biosignatures like oxygen+methane—and even industrial pollution. Keywords: aliens, convergent evolution, octopus eyes, carcinization, red dwarf, infrared, JWST, exoplanets, biosignatures.
