It depends on how you define evolution. I've mentioned Olaf
Stapledon before. He's not well known enough, but even though many
of his ideas are outdated, he did come up with some highly original
outcomes which have been much copied since.
The first problem is that we haven't taken complete control of our
environment. We've got rid of most of the predators, but when we
encounter volcanoes, earthquakes and so on, we die. There's little
we can do about them. And we're a problem in ourselves.
Overbreeding, and poisoning ourselves. Not to mention killing each
other in many places like in the Sudan. Then of course there's
threats beyond the Earth, and enough stories have been written on
all of those.
The second problem is whether this evolution includes genetic
modification, cybernetic life, cloning etc etc. Some people have
talked as if artificial life is the next step in evolution after us.
I wonder though if that counts as evolution. It implies evolution is
a kind of spiritual force, rather than scientific.
I thought this was an interesting comment in line with some of my
"Gary Propheter, Medford, Ore.:
"Unfortunately, I see humankind evolving into the domesticated
version. One of the key aspects of civilization has been the
declining emphasis on individual ability (intelligence/skill) and
the increasing impact of genetic resistance to disease. Modern
medicine and genetic engineering will only strengthen this trend as
religious traditionalists will prevent measurable diversion
from "God's creation." In time ... a new disease will rip out the
heart of societies worldwide (remember the black plague?) and all
that will be left are some lemmings who don't understand their tools
well enough to continue to survive."
The big danger though, and I see this in a lot of the posts is
imagining the world from how the western world is now. We're the
minority, and a shrinking one.
"Shirley, Grain Valley, Mo.:
"Well, this isn't my own idea, but I like it. It's based on a book I
just re-read "Darwin's Radio," by Greg Bear. In this book, big
jumps are made in our evolution in one generation. The change is
motivated by our own genes in response to our environment (That's
one theory in the book.) ..."
Anyone read this?
