In a Sheep Population, Researchers Find a Fitness Gene
52757
The Soay sheep of St. Kilda, a group of small Scottish islands, have been living free and unfettered for millennia. While these primitive sheep are still unmanaged, detailed records have been kept on them for the past 20 years. That makes St. Kilda a kind of natural evolutionary experiment, an island-scale Petri dish where sheep, not fruit flies, are the subjects.
