Evolution is progressive

One of the more common misconceptions, with a history extended ahead Darwin, is that evolution is make outive; that things fare more interlacing and perfective in some way. In fact, this view is attributed more to tender and religious attitudes of 18th and 19th blow European husbandry than to any evidence.

Of course, heterodox writers (usually not biologists) like Teilhard and Koestler remained progressionists long after this. merely by the 1970 s, progress had been abandoned by working biologists. Recently, the topic has resurfaced, shorn of the mysticism of earlier debates. life scientist J.T. Bonner argued that there was a rise in complexness of organisms everyplace the long name [1988], and others were arguing for a form of topical anaesthetic progress under the terms arms race [Dawkins and Krebs 1979] and escalation [Vermeij 1987].

Gould [1989] felt so strongly about it he was moved to deny that, at least since the Welsh explosion, there has been any progress at all. Much of the modern debate centres on what counts as progress. Gould [1996] thinks that the apparent trend to complexness is just a matter of random evoluti on that started at a minimal wall of complex! ity: Others [cf Nitecki 1988] claim that there is oneness progress because any increase over zero is a net increase, and that different measures will give different...
