- No need for a mea culpa. In your posts, and our email exchange, you
- were consistent in your usage. Anyone with an ounce of intelligence
- (and a shred of intellectual honesty) should be able to pick up the
- context of the material and decide (at least unconsciously) whether
- strictly natural selection or cumulative natural selection (implying
- other mechanisms) is being discussed. Johnson, in his book, seems unable
- or unwilling to make this distinction (see Chapter 2). In fact, he
- gets a lot of mileage out of letting the definitions slide.
-
- After reading Johnson's book, I reread my FAQ and found that I use
- the word "selection" several times and don't explicitly draw a distinction
- between the two -- that's being fixed.
-
- I hope Johnson hasn't left for good yet; I wouldn't mind a discussion
- of the evidence concerning common descent. I'm not going to hold my
- breath, however. In my post about microevolution and macroevolution
- the only part he were responded to was that I didn't think biologists
- were hiding things. He then went on to claim evolutionists were all
- just indoctrinated or blinded by ideology. For a guy who claims to
- to want to discuss the evidence, he sure does a marvelous job of
- avoiding it.
