When ancient humans left Africa and moved around the globe, they likely met new environments and challenges.
Previous research on genomic data shows ancient humans most likely left Africa and spread across the planet between 60,000 and 50,000 years ago.
By studying both ancient and modern genomes, we have shown genetic selection was probably an important facilitator of this ancient human diaspora.
Genetic, archaeological and climatic evidence all suggest these ancient humans were most likely living in and around the Arabian Peninsula.
The changes would also have prepared the ancient humans for the cold Eurasian climates they would eventually encounter.
