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.
