By Chuck Missler November 24 will mark the 150th anniversary of Charles Darwin's book On the Origin of Species, one of the most influential books on biology ever written, and arguably the most controversial. One hundred and fifty years after Darwin made popular the idea that the diversity of life on planet Earth today descended (or ascended?) from lower life forms over millions of years, the general theory of evolution is still not accepted by vast numbers of people, to the chagrin of large numbers of evolutionary biologists.
Did all of life really descend from one-celled organisms that developed in primordial waters billions of years ago? Is that really what happened? If so, we should see plenty of evidence of it all around us, and there are significant numbers of scientists who argue that we indeed find just that. They argue that there are a sufficient number of transitional forms in the fossil record to support Darwin's theory. They argue that natural selection, acting to preserve small beneficial mutations and weed out the bad ones, can indeed slowly but surely bring about the development of sophisticated structures like eyes and circulatory systems. These scientists may disagree over specifics, but in general buy the evolutionary model of origins.
