Obsterical implications of waterside hypothesis

ili samo pasus o devama:

Exploring placentophagy is important since all land mammals eat the placenta. If eating the placenta has never been instinctive among our ancestors, this would be another common point with sea mammals, including cetaceans and seals. Interestingly, from this regards, camels are the exceptions among land mammals: they do not eat the placenta. Camels have another particularity among land mammals: like Homo sapiens and sea mammals they have kidneys with medullary pyramids (cf. the chapter by Marcel Francis Williams about marine adaptations in human kidneys). Since camels consume highly salty plants and drink the water of salty ponds, and since, from obvious reasons, sea mammals also have easy access to hypertonic salty substances, one can suggest that placentophagy might be correlated with the urgent need in specific nutrients, particularly minerals, in the post partum period. It is as if placentophagy and non-pyramidal renal medullas were features shared by mammals that do not have access to hypertonic salty substances after parturition. Such correlations should inspire further research that would take into account the concept of sodium pump across the trophoblast membrane and the specific composition in electrolytes of the trophoblast cytoplasm. Can camels from the desert help us to accept our waterside origins?


Hipoteza je, dakle, da je ljudska vrsta u samom pocetku, zivila blizu mora (vode), hraneci se morskim plodovima. Nejedenje placente zajednicko nam je s morskim sisavcima i devama koje jedu slane biljke i piju vodu iz slanih izvora.
