1. What is Ancient Plant DNA?
Ancient plant DNA refers to genetic material preserved in long-buried plant remains, such as seeds, leaves, wood, or even pollen. Scientists recover these DNA fragments from fossils, sediments, and frozen soils like permafrost. Unlike traditional fossil records, which show only physical forms, ancient DNA reveals genetic adaptations and diversity over time. Advanced techniques allow researchers to piece together these fragile genetic traces, opening a window to how ancient plants responded to past environmental changes. Learn more at Nature.
