Evolutionary biology has long sought to explain how new traits and new species arise. Darwin maintained that competition is key to understanding this biodiversity and held that selection acting to minimize competition causes competitors to become increasingly different, thereby promoting new traits and new species. Despite Darwin's emphasis, competition's role in diversification remains controversial and largely underappreciated. In their synthetic and provocative book, evolutionary ecologists David and Karin Pfennig explore competition's role in generating and maintaining biodiversity. The authors discuss how selection can lessen resource competition or costly reproductive interactions by promoting trait evolution through a process known as character displacement. They further describe character displacement's underlying genetic and developmental mechanisms. The authors then consider character displacement's myriad downstream effects, ranging from shaping ecological communities to promoting new traits and new species and even fueling large-scale evolutionary trends. Drawing on numerous studies from natural populations, and written for a broad audience, Evolution's Wedge seeks to inspire future research into character displacement's many implications for ecology and evolution.

This book tells the sweeping story of the role that East African savannas played in human evolution, how people, livestock, and wildlife interact in the region today, and how these relationships might shift as the climate warms, the world globalizes, and human populations grow.Our ancient human ancestors were nurtured by African savannas, which today support pastoral peoples and the last remnants of great Pleistocene herds of large mammals. Why has this wildlife thrived best where they live side-by-side with humans? Ecologist Robin S. Reid delves into the evidence to find that herding is often compatible with wildlife, and that pastoral land use sometimes enriches savanna landscapes and encourages biodiversity. Her balanced, scientific, and accessible examination of the current state of the relationships among the region's wildlife and people holds critical lessons for the future of conservation around the world.
