A new discovery that fish may have once swum across the Sahara could shed light on how humanity made its way out of Africa, say researchers.
The cradle of humanity lies south of the Sahara, which begs the question as to how humans made its way past it.
The new study has suggested that the Sahara might not have been quite as impassable as once thought-not only for humanity, but for fish as well.
"Fish appeared to have swam across the Sahara during its last wet phase sometime between 10,000 and 6,000 years ago," Live Science quoted researcher Nick Drake, a geographer at King's College London, as saying.
"The Sahara is not a barrier to the migrations of animals and people. Thus it is possible - likely-that early modern humans did so, and this could explain how we got out of Africa," said Drake.
