History, not age, determines the genomic importance of ancient trees

Дата публикации: 12-08-2026 19:20:07

Ancient trees—those that are remarkably old for their species—are declining worldwide, raising concerns about the loss of the ecological and evolutionary history they represent. Their exceptional longevity has long encouraged the idea that they act as genetic reservoirs, preserving variation that may have been lost from younger populations. But does great age itself make an ancient tree genetically unique?
