If you would, consider it in terms of brain function as an analog of
computer function. We have more advanced software, and many of our brain
functions are attuned to rapidly changing and otherwise dynamic
While there might be devolution or lack of difference-based development as a
large portion if not majority is watching the same channels and reading the
same news feeds, by the same token such technological and social
advancements as non-geographic community via the Internet are the sputnik of
global development in wide-ranging areas.
In the past twenty-five years, computer processing power has increased by
factors of millions of times per dollar.
I have read some Bear books, not that one.
Genetic mutations spawned by cosmic radiation may be at the same rate as has
been the case over the course of human evolution. A lower barrier to entry
to life via enhanced survivability and decreased infant mortality gives a
more diverse gene pool, with parts more advanced.
In terms of peoples' brains, there is change over even the last fifty years,
not all good or bad or advancement or decline, yet it is change and humanity
is as strong as ever for it, and thus it is evolution.
