Along with other oddities of growing old, insomnia seems to be common. I don’t have any trouble falling asleep, but I wake about four each morning with the monkeys run through my mind dragging random thoughts that seem to keep me awake.
We view ourselves today as fait accompli, the final, perfect product in the tree of evolution.
There is some justification for that thinking, since evolutionary differences have resulted from adaptive changes among isolated groups to specific environments: Aboriginal in Australia differ from pigmies in Africa and differ from Nordic populations in northern Europe…
Today, with the ease of world travel people are less isolated resulting in more cross-cultural societies.
It seems likely to me that the next evolution of humankind will not happen in isolated societies, but as the result of the ease of global travel, we will experience assimilation – moving toward a homogeneous race.
Cultural accommodation has more effect on our actions than logic and biological adaptation, so it will take the dying off of most generations living today to asphyxiate the idea of racial purity.
In our egocentricity, we view time over the period of our lifespan, but time is a continuum. As important as we think we are, humankind will evolve over time, just as we always have – unless we bring about our own destruction.
