More info on these may be added if requested. Happy hunting everyone.

The analytical eyes mutation can be obtained from eating an Ocular Orthopod, which resembles a tiny eyeball, complete with lashes, atop a stick with legs. They are found in the Tundra starting from "Part Two" of the game. Some quick spoilers, if you're unsure whether you're there yet or not: Part two begins shortly after .

Once a Trebhum has the mutation, simply control them and look at a creature to scan it. A circle will appear on the screen and fill in to indicate progress toward the scan. Distance required from the creature seems to vary by creature, so try getting closer if it isn't working. Be careful around predators!
