Eye color Light and light-mixed eyes (16–12 in Martin scale) Pure light (16–15 in Martin scale) Light-mixed (14–12 in Martin scale) Mixed eyes (11–7 in Martin scale) Mixture of light eyes (blue, gray or green) with brown when light and brown appearance is at the same level. Dark and dark-mixed eyes (6–1 in Martin scale) Amber eyes are of a solid color and have a strong yellowish/golden and russet/coppery tint. This may be due to the deposition of the yellow pigment called lipochrome in the iris (which is also found in green eyes). Amber eyes should not be confused with hazel eyes;
Molecular anthropology a limited scale up to the late 1990s when the staff at the Max Planck Institute shocked the anthropology world by sequencing DNA from an estimated 40,000-year-old Neanderthal. The result of that experiment is that the differences between humans living in Europe, many of which were derived from haplogroup H (CRS), Neandertals branched from humans more than 300,000 years before haplogroup H reached Europe. While the mtDNA and other studies continued to support a unique recent African origin, this new study basically answered critiques from the Neandertal side. Significant progress has been made in genomic sequencing since Ingman and colleague
