Oral tradition in Kenya tells that 20 shipwrecked Chinese sailors washed up on shore in the 15th century and were given permission to settle and marry into local tribes. DNA tests conducted by China’s government in 2002 on one of the supposed descendants and found that she was of Chinese descent.
The same Gene that causes Asian people to “flush” when drinking alcohol causes a 4 times increase in DNA damage, and a much higher rate of heart and cancer problems from drinking alcohol.
Of all the humans tested so far, everyone has contained the same DNA from 1 of at least 2 ancestors. Mitochondrial DNA being traced back matrilineally to a specific “mT-Eve,” and a Y-chromosome being traced back patrilineally to a specific “Y-chromosomal Adam.” We are not descended from a singular couple, but rather we are all seemingly descended from singular ancestors that may have lived hundreds of thousands of years apart.
Known as Cheddar Man, a 9,000 year old skeleton was found in a cave in Cheddar, England. After DNA testing, a living relative was found half a mile away, linking back 300 generations.
From 1993 to 2008, the same DNA was discovered at 40 different crime scenes in Europe, leading to the investigation of the “Phantom of Heilbronn”, which turned out to be a woman working in a cotton swab factory who inadvertently contaminated the swabs with her own DNA.
3 men whom broke into a luxury store in Germany and ran off with $6.8M worth of jewelry. They left behind a piece of evidence, sweat. DNA analysis led to not one but two suspects- identical twins. They couldn’t determine from which one. They went free.
Despite having DNA evidence of the suspect, German police could not prosecute a $6.8M jewel heist because the DNA belonged to identical twins, and there was no evidence to prove which one of them was the culprit.
Experiences you have throughout your life, leave chemical markers on your DNA; essentially ingraining superficial experiences into your descendants.
Just 1 gram of DNA is theoretically capable of holding 455 exabytes – enough for all the data held by Google, Facebook and every other major tech company, with room to spare
A woman faced fraud charges after a DNA test showed she wasn’t the mother of her own children. She was in fact a chimera. Those rare individuals, dubbed “Chimeras”, had started out as twins; in the early stage of pregnancy, one of the twins had merged with – been absorbed by, one could almost say – the other twin. The cells of the consumed twin, however, did not disappear and remained alive in one concentrated area of their sibling’s body. In essence, a human chimera is one person made up of two separate sets of genetic material; they are, in fact, their own twins.
