Her timeline of Mitochondrial Eve of 6,000 years is a little bit out by over 220,000 years. What has gone wrong with Usher's calculations?
- 270,000 years ago: age of Y-DNA haplogroup A00 ("Y-chromosomal Adam").
- 250,000 years ago: first appearance of Homo neanderthalensis (Saccopastore skulls).
- 250,000–200,000 years ago: modern human presence in West Asia (Misliya cave).
- 230,000–150,000 years ago: age of mt-DNA haplogroup L ("Mitochondrial Eve").
