The old concept of the ladder of progress still lingers on in the form of a teleology: Evolution is good for species, and so they strive to make it go faster.

Sex and gene repair and the sophisticated screening mechanisms of higher animals to ensure that only defect-free eggs and sperm contribute to the next generation—all these are ways of preventing change.
