Speaking of migrations, over the past decade the genetic sampling has enabled research into genographic patterns. This data was applied to a test in Astoria Queens. National Geographic:
“In recent centuries those prehistoric paths have reconnected in New York and other immigrant havens. “From the beginning of the project,” Wells says, “I’ve wondered if it would be possible to sample all the major lineages on Earth on a single street.” On 30th Avenue he almost did—the 193 volunteers turned out to be carrying genetic markers for virtually all the major migrations that peopled the continents. The only missing lineage was the oldest one, which Genographic scientists found in Khoisan hunter-gatherers in southern Africa; their ancestors initially diverged from other modern humans more than 100,000 years ago.”
Two similar maps from the National Geographic, the one (above) from the current article and same map (below) from 2006 (ancient). You can see how the snazzy graphics dropped the key component out of the map, namely the numbers for migration sequence.
