'Creation science' has not entered the curriculum for a reason so simple and so basic that we often forget to mention it: because it is false, and because good teachers understand exactly why it is false.

Organisms are not billiard balls, propelled by simple and measurable external forces to predictable new positions on life's pool table. Sufficiently complex systems have greater richness. Organisms have a history that constrains their future in myriad, subtle ways.

We must [it has been arued] go beyond reductionism to a holistic recognition that biology and culture interpenetrate in an inextricable manner.

Science is all those things which are confirmed to such a degree that it would be unreasonable to withhold one's provisional consent.

Acquired characteristics are inherited in technology and culture. Lamarckian evolution is rapid and accumulative. It explains the cardinal difference between our past, purely biological mode of change, and our current, maddening acceleration toward something new and liberating- or toward the abyss.

You put three facts together - that all organisms produce more offspring that can survive, that there's variation among organisms, and that at least some of that variation is inherited - and the syllogistic inference is natural selection.

The proof of evolution lies in those adaptations that arise from improbable foundations.
