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. 410 0$aOrganisms and environments ;$vno. 12 606 $aDivergence (Biology) 606 $aCompetition (Biology) 606 $aAnimal diversity 615 0$aDivergence (Biology) 615 0$aCompetition (Biology) 615 0$aAnimal diversity. 676 $a577.8/3 686 $aWH 3000$2rvk 700 $aPfennig$b David W$g(David William),$f1955-$01896084 701 $aPfennig$b Karin S$g(Karin Susan),$f1969-$01896085 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910960707003321 996 $aEvolution's wedge$94550380 997 $aUNINA
