I thoroughly enjoyed this book. For many years, I've considered the understanding of our evolutionary drive towards dominance hierarchies to be of utmost importance to the future direction of our species. Rare are books that address this topic. Rarer still are books that address it as succinctly and pragmatically as this. Until, as the authors assert, we come to understand and accept the biological roots of our natures, we're doomed to the same endless cycles of oppression and violence we have seen throughout recorded history. To control our nature, we must acknowledge the truth of our nature.

Although slightly out of date now, and out of print, this is still an extremely interesing and comprehensive survey of the original puncutated equilibrium question.
