Descendant leaving success is. They are those who leve the most descendants. Obviously this was a joke. Your religious bias is showing. Evolution makes no value judgements.
Degeneration is simply a term opposed to evolution, neither contains a value statement.
Also, although some may use Darwinism as a blugeon with which to club the religious, most evolutionists don't. In fact, many of us have no idea about the origin of life. What we do have an idea about, however, is the fossil record of human evolution, which is today fairly complete. Darwin worried that no missing links would be found. Ah yes, evolution theory is correct, whatever the facts.
