Data from: Intense selective hunting leads to artificial evolution in horn size

Gabriel Pigeon, Marco Festa-Bianchet, David W. Coltman & Fanie Pelletier
The potential for selective harvests to induce rapid evolutionary change is an important question for conservation and evolutionary biology, with numerous biological, social and economic implications. We analyze 39 years of phenotypic data on horn size in bighorn sheep (Ovis canadensis) subject to intense trophy hunting for 23 years, after which harvests nearly ceased. Our analyses revealed a significant decline in genetic value for horn length of rams, consistent with an evolutionary response to artificial...
