Imagine sightless animals with otherwordly senses, pinging your innards with sonar or recognising you by the thermal pattern of your warm throat, your cold nose and old hair. As evolution on Earth has been following that path for quite some time, it is not easy to come up with strikingly different designs that work at least as well as familiar ones.ĭoing away with eyes is such a major departure from 'earth standard', increasing alienosity significantly. Darwinian evolution tends towards optimisation, which in reality means the optimal balance between function and cost economy of design pervades everything in biological evolution. The word 'alienness' is perhaps grammatically correct, but lacks punch something like 'alienosity' might do the trick.įrivolity aside, striking a balance between oddity and plausibility is difficult. I guess almost everyone who designs fictive alien life forms want them to look truly 'alien': you want your animal to have something that tells the viewer that this is an original it should look unearthly and yet as if it ought to look that way.
