This article discusses the attempts of scientists from the U.S. Agricultural Research Service, along with University of Alaska-Fairbanks (UAF) professor Matt Cronin, to compare a herd of feral cattle on Chirikof Island to commonly used livestock breeds. The feral cows have managed to survive for more than 100 years on the deserted, treeless island with little or no human management. The scientists are comparing genetic features by isolating DNA through blood, semen, or tissue samples from the Chirikof species as well as from beef cattle. The commercial breeds that exhibited the greatest similarity to the feral herd were Highland, Hereford, and Angus.
