Because the white genes are mutations of the genes of the original men of color — and males are mutations of the original females — we can finally answer the question Is God black? The answer is Yes, She is.

It seems that the origin of the mutations is in the consumption of contaminated water.

Scientists are now using a genetic approach to estimate the ages of corals. The method determines when a coral egg and sperm originally met to form the genome of a coral colony. The researchers then track the number of mutations that have accumulated in the genome since that time. Because mutations tend to arise at a relatively constant rate, researchers can estimate the approximate age of the coral genomes in their study.
