New study looks at ancestral human migration into Asia:
Researchers mapping a massive array of genomes across Asia say they have found evidence that humans covered the continent in a single migratory wave, and share a common ancestry.
The findings were released by the Human Genome Organisation (HUGO) Pan-Asian SNP Consortium which looks at single-nucleotide polymorphisms (SNPs), or variations at individual bases that make up the genetic code. The results challenge the view that Asia was populated by at least two waves of migration.
