The St Kilda Soay Sheep Project is a pioneering research initiative that has tracked wild sheep for over 40 years to understand how genetics, environment, and climate shape life. Its results are now used to shed light on everything from aging and evolution to the impacts of climate change on nature.
A 40-year research project reveals the secrets of aging, climate, and survival in the wild.
In the middle of the harsh North Atlantic lies the small Scottish archipelago of St Kilda, where a population of wild sheep has lived undisturbed for centuries. For more than 40 years, scientists have followed over 15,000 Soay sheep from these remote islands – making the project one of the world’s most famous long-term famous long-term studies of a wild population.
Researchers behind the St Kilda Soay Sheep Project (SSP) have collected lifelong data on every single animal: their birth, diseases, family relationships, genes, and causes of death. This has provided unique insight into how nature itself shapes development, aging and survival – far from the controlled conditions of the laboratory.
The project has trained and inspired many young scientists from around the world. It is built on values of curiosity, collaboration, responsibility, and openness – with all data made freely available to other researchers.
The sheep of St Kilda help us understand some of life’s biggest questions: how we age, how climate shapes wildlife, and how nature adapts in a changing world.
