  • Scientists have solved the mystery of the origins of ancient baobab trees.
  • According to DNA studies, the iconic trees first arose in Madagascar 21 million years ago.
  • Their seeds were later carried on ocean currents to Australia and also to mainland Africa, evolving into distinct species.
  • Six of the world’s eight baobab species are indigenous to Madagascar, where the distinctive trees with giant trunks have historically grown in huge forests.
  • Baobab trees can live for 1,000 years and one hectare of land can support eight fully grown baobab trees.
  • Madagascar is also the home of the world’s rarest baobab, Adansonia perrieri.
  • large-bodied animals such as giant lemurs or giant tortoises played a crucial role in spreading the seeds of baobab trees in their dung.
  • But they became extinct about 500 years ago.
  • Without these animals, baobab seeds are not spread as effectively.
