Other key findings include evidence strengthening the case that fossils in South Africa might be those of the ancestor of the human lineage. Research also suggests humans crossed what is now the desolate Arabian Desert to expand out of Africa across the world.

Although some researchers once scoffed at the notion that our ancestors interbred with such extinct lineages, genetic analysis suggests that Neanderthal DNA makes up 1 percent to 4 percent of modern Eurasian genomes, while Denisovan DNA makes up 4 percent to 6 percent of modern Melanesian genomes....
