And thanks to persistent gene flow from the animals&apos historical population — meaning genes from one population are carried to another — and moderate genetic diversity, the species is likely to adapt nicely to its extended habitat and may continue to expand its range, the scientists predicted.
|
|
Yet, despite this low genetic diversity, long considered a harbinger of a species' pending doom, narwhals have thrived for a million years and even rapidly grown in population recently, with no signs of stopping soon—at least if we humans don't threaten their existence with climate change.
