Abstract
Human beings experience themselves through various kinds of collectively experienced time. Medicine that relies upon precarious forms of ancestral or evolutionary explanation generates such collectively experienced forms of time, which are thus essentially politico-medically instituted versions of kin relations. Kin relations structure our ethical relations to each other rather thoroughly, even in Western modernity, especially through legally sanctioned relations. Hence, an ancestral or evolutionary explanation in medicine should be examined for its ethical import via its structuring of etiologically linked kin relations, even if those relations extend beyond the family, people, population or group context back into cosmic and evolutionary origins.
