Africa has the world’s greatest genetic diversity, yet it’s missing from research: we’re filling the gap

Most genetic studies focus on people from European ancestry. But Africa has the richest diversity and must be included in genetic databases.

Where did the first people come from? The case for a coastal migration from southern Africa

A coastal migration up and out of Africa was more likely to succeed than an overland journey.
There are wild apple orchards across France, including on the Saclay plateau south of Paris.

‘Noah’s arks’ for fruit trees: How conservation orchards preserve and boost biodiversity

Faced with the collapse of biodiversity, there is an urgent need to protect the genetic diversity of species. But to preserve fruit trees, seed banks are not enough.

Baobab trees all come from Madagascar – new study reveals that their seeds and seedlings floated to mainland Africa and all the way to Australia

New research has found that the world’s baobab trees all evolved on Madagascar 21 million years ago. Sometime in the last 12 million years, they floated on piles of debris to Australia and Africa.

African wild dogs will soon have their own sperm bank – how artificial breeding will help them survive

The African wild dog has been left without habitat to naturally disperse and breed. Scientists will set up the first-ever sperm bank to inseminate wild dogs and ensure that the species survives.
