Earth’s biodiversity is in crisis. An imminent “sixth mass extinction” threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity – or variation – within species.
This variation in genes within a species is crucial for their ability to adapt to changes in the environment or resist diseases. Genetic variation is therefore crucial for species’ long term survival.
Traditional conservation efforts – such as protected areas, measures to prevent poaching, and captive breeding – remain essential to prevent extinction. But even when these measures succeed in boosting population numbers, they cannot recover genetic diversity that has already been lost. The loss of a unique gene variant can take thousands of years of evolution before it is recovered by a lucky mutation.
