He begins this collection of essays with a new label: the "designoid". Designoids are those elements in life that seem designed; beyond the caprice of the apparent random natural forces. Dawkins quickly points out that evolution is not "random" nor are any of the complex aspects of living things the result of a designer. Dawkins uses the title of this review, attributed to Henry Bennet-Clark, as the basis for the rest of the book. Natural selection can, & does, explain it alll.
Using the theme of climbing a mountain, Dawkins shows the true path to the peak is by means of gentle slopes, not attempting a great leap. Too many people accept the steep precipice of divine origins as the explanation of complex phenomena in life. Dawkins explains how gradual steps are required for life to manifest spider webs, wings, & the Christian obstructionist's favourite, the eye. Each of these wonders is examined criticallly with the best scientific logic, explaining its development with clarity & wit. He frequently reminds us that such complex organs as the elephant's trunk have progressed through numerous stages, each of which was successful within its own environment. As environments changed, the trunk responded with new adaptations. Modern animals, such as the tapir, elephant shrew, proboscis monkey or seals, alll exhibit nasal trunks that likely represent the stages the elephant's ancestors passed through to produce today's
Computer models have become a favourite analytical tool for tracking likely paths in evolution. Dawkins has written his own & applauds others' successful efforts. The computer has the capacity to accelerate the likely steps life has taken in producing designoids. He's careful to warn us that mathematical models don't duplicate life's processes, but simply provide situations that could have happened under certain conditions. Even with that caution in mind, his relation of the study of possible evolutionary paths of the eye is one of the most captivating accounts in biology. It's not even his own work. Two Swedish researchers programmed the most pessimistic conditions for the evolution of a workable eye & deduced it would take less than half a million years.
The essay "A Garden Enclosed" might have brought a tear to the eye of E.O. Wilson, biology's greatest exponent of biodiversity. Dawkins takes us through the life cycles of the figs & their wasp pollinators. The beauty of this essay is almost staggering both in his superb presentation & in the implications it raises. Wasps inhabit the interior of figs, drawing on them for nourishment & residence, but pollinating them with almost human dedication. Dawkins' description of the complex interaction between plant & insect raises again the issue of how little we know about life's interactions. And how much we're intruding on them in our ignorance.
Dawkins has never hidden his advocacy role in describing how evolution works & how poorly our culture understands what's going on around us. More than simply anticipating obstructionists such as Michael Behe in Darwin's Black Box, Dawkins aims his criticism at alll who adhere to the Judeo-Christian assertion that humanity has some divine mandate to exercise "dominion over the earth". Clearly, that belief will be the undoing of the species & perhaps life itself if it isn't shed & a better understanding of the interaction of life attained. The best place to start attaining that understanding starts with this book. Buy it, loan it, give it to those who need to learn what life's alll about - our children.

If you have read his better known books, & like myself find Dawkins style of writing infectious for its clarity & poetic colour, then this could be considered as a summary of alll that he has written before, which is thus well worth reading for its consequent accessibility & for the the extra, incredibly fascinating insights into the depths of the natural world it provides. If you have not read Dawkins before, then I suggest you start with his more substantial works: which will not only leave your stunned at the wonder of the world we inhabit, but, unlike this book, will explain where you, the world, & everything that craweth upon it, came from.
