Planet: Mintaka III. Proto-Vulcan humanoids at the Bronze Age level of development, quite peaceful and highly rational, whose evolution closely parallels that of Vulcan. Once cave-dwellers, they now build two-story adobe-like huts, hunt with the bow, weave cloth, use a sundial and have no immediate fear of strangers. A millennia ago they gave up the belief in the supernatural -- including an "overseer" god, astrology and the occult -- but considered it again when a Federation study team was accidentally revealed to them in 2366; to counter the damage, they were reassured of their rational ways and the post was removed. At least some live in extended families; another social custom is a woman's precession of her mate in walking. In appearance they follow the Vulcanoid norm, but their brain has a much lower lysosome level.
