British swallowtail split from European cousins much earlier than thought, study finds
A study has found that the British swallowtail butterfly has been a distinct subspecies for at least 200,000 years, much earlier than previously believed. The research suggests it separated from its European relatives long before the flooding of Doggerland and may have once been more widespread in northern European wetlands. This discovery could influence conservation strategies, emphasizing the unique genetic status of the British swallowtail, which is now found only in Norfolk and faces threats from rising sea levels.
A study shows the British swallowtail butterfly has been a separate subspecies for at least 200,000 years, much longer than previously believed.
This finding changes how conservationists approach protecting the butterfly, which is unique to Britain and at risk from climate change.
The story highlights the importance of understanding biodiversity and the need for targeted conservation efforts in the face of environmental change.
