By obtaining a sense of its place in the unfolding drama of life, set in an ecological theatre, so we can understand why it has become one of the leading players.

I am puzzled that Conway Morris apparently doesn't grasp the equally strong (and inevitable) personal preferences embedded in his own view of life.

I am driven to observe of the ultra-Darwinists the following features as symptomatic. First, to my eyes, is their almost unbelievable self-assurance, their breezy self-confidence.

Life's Solution builds a forceful case for the predictability of evolutionary outcomes, not in terms of genetic details but rather their broad phenotypic manifestations. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions.

The long history of mankind is studded with convergences, perhaps most notably in social systems and the use of artefacts and technology. But for human history, set in the arrow of time, there appears to be one intolerable stumbling-block. This is the catastrophic failure in human values and decency.

It seldom seems to strike the ultra-Darwinists that theology might have its own richness and subtleties, and might strange thought actually tell us things about the world that are not only to our real advantage, but will never be revealed by science.

The way Conway Morris goes about biting the hand that once fed him would make a shoal of piranha seem decorous.
