  • RE: "Rapidly declining body temperature in a tropical human population" Increasing Testosterone

    I suggest the basis of the findings of Gurven, et al., is increasing testosterone within the population with time. It is known that low testosterone exhibits increased temperature (Physiology Part A: PhysiologyVolume 70, Issue 2, 1981, Pages 247-250). It is my hypothesis that human evolution is caused by selection for increasing testosterone. Therefore, I suggest increasing testosterone is the basis of Gurven, et al. For sake of demonstration, It is my hypothesis that COVID-19 infection and subsequent pathology are caused by low dehydroepiandrosterone (DHEA), which can be exacerbated by an increase in the ratio of testosterone to DHEA (© Copyright 2020, James Michael Howard, Fayetteville, Arkansas, U.S.A.) This rapid increase in temperature within a population could support why COVID-19 is pandemic at this time.

If your library does not subscribe to “Rivista … ,” you may find this at: where you may also see a chart of testosterone in humans and great apes which directly supports my hypothesis and was reported in the literature 2 years later.)
