Scimex: A US study has found that Europeans experience higher rates of a
specific type of mutation associated with exposure to ultraviolet light
compared to Africans and Asians, suggesting that the human mutation rate
has not stayed the same across all races since the emergence of modern
humans. The researcher compared mutations in the genomes of Africans,
Asians, and Europeans, and reports that the human mutation rate may have
evolved more rapidly than previously thought.
A comparison of genetic mutations within the genomes of Africans,
Asians, and Europeans in the 1,000 Genomes database reveals that
Europeans experience higher rates of a mutation associated with exposure
to ultraviolet light than do Africans and Asians, suggesting that the
human mutation rate may have evolved more rapidly than previously
thought, according to a study.
