All humanity has a common (8000x) grandmother. An African woman who lived 200,000 years ago is the common maternal ancestor of all humans alive today.
A father’s genes promote the baby’s weight in the womb, regardless of maternal health, while a mother’s genes limit the baby’s weight, regardless of fetal health, and a delicate balance is achieved via this conflict.
Over 99% of Koreans lack a gene called ABCC11. The gene is what causes the body odor. Only 2% of Europeans have this same mutation.
All living humans are related to a single woman through unbroken, maternal line. She is known as Mitochondrial Eve and is estimated to have lived around 100,000 – 200,000 years ago. All living men are related to a single man through an unbroken paternal line. That man is known as the Y-chromosomal Adam and he is estimated to have been lived 200,000 to 300,000 years ago.
There is something called Genetic memory, an example are butterflies who remember their migration route even though it takes three generations to complete.
White supremacist and racist Craig Cobb said he would take a genetic test, and receive the results on live television. He was found to be 14% Sub-Saharan African.
Because of a lucky genetic mutation happened in the 18th century, today 38 people in a small town in northern Italy don’t suffer from cholesterol artery-clogging, making them virtually immune to heart disease and strokes. They all smoke, they eat like hell, and they don’t care.
For a science fair experiment in 1969, a 14 year old scientist used genes to change chicken feathers from white to partially black, which his teacher said was playing God.
Geneticists believe that everybody on earth is at least 50th cousin to everybody else.
1-in-4 people of the Doma tribe in Zimbabwe have only two toes on each foot. This is due to a law that forbids marriage outside of the tribe, thus propagating the mutation due to a limited gene pool.
