The famous trees first appeared in Madagascar 21 million years ago, based on DNA analysis.
Later, their seeds spread to Australia and continental Africa by ocean currents, where they gave rise to new species.
Because they believe the trees may be closer to extinction than previously believed, the researchers are advocating for increased conservation efforts for the species.
Because of their unusual shapes and lengthy lifespan, baobabs are referred to as “the tree of life” or “upside down tree”. The combination of massive deforestation and climate change has put them in danger.
Working on the research was Dr. Ilia Leitch of the Royal Botanic Gardens, Kew, and her husband, Prof. Andrew Leitch of Queen Mary University of London.
