Ancient DNA Sequencing
Since Krings Neandertal mtDNA have been sequenced, and the sequence similarity indicates an equally recent origin from a small population on the Neanderthal branch of late hominids. MCR1 gene has also been sequenced but the results are controversial, with one study claiming that contamination issues cannot be resolved from human Neandertal similarities. Critically however no DNA sequence has been obtained from Homo erectus, Homo floriensis, or any of the other late hominids. Some of the ancient sequences obtained have highly probable errors, and proper control to avoid contamination.

Famous quotes containing the words ancient and/or dna:
“We Irish, born into that ancient sect
But thrown upon this filthy modern tide
And by its formless spawning fury wrecked,
Climb to our proper dark, that we may trace
The lineaments of a plummet-measured face.”
—William Butler Yeats (1865–1939)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
