A 9,000-year-old skeleton was found inside a cave Cheddar, England, and was nicknamed “Cheddar Man.” His DNA was tested, and it was concluded that a retired history teacher living nearby was a direct descendant of Cheddar Man.

In 2009, identical twins Hassan and Abbas O. were suspects in a $6.8 million jewelry heist. DNA matching the twins was found but they had to be released citing “we can deduce that at least one of the brothers took part in the crime, but it has not been possible to determine which one.”

A full operating system and a film were stored on DNA and recovered with no errors. 

Lobsters do not weaken, slow down, or lose fertility due to aging. This may be due to an enzyme called telomerase that repairs DNA sequences.

In 2009, a woman claimed Keanu Reeves had hypnotized her, disguised himself as her ex-husband, and impregnated her. She sued him for $3 million for spousal support, and $150,000 per month in retroactive child support for her four adult children. DNA testing proved he wasn’t the father.

There is a slug that can “borrow” DNA from algae it eats giving it the temporary ability to perform photosynthesis. It is the only known animal to do this.

DNA decays with increasing rapidity in the presence of heat, water, sunlight, and oxygen. Under the most ideal conditions, DNA can theoretically survive for a maximum of one million years.

A female serial killer named “Phantom of Heilbronn” was linked to 40 crimes, six of which were murders. In 2009 it was discovered that she didn’t exist and her DNA was simply contamination from the cotton swabs used at the crime scenes.

Two identical twins had sex with the same woman on the same day. She got pregnant and there’s no way to tell who the dad is because the DNA test claims both men have over 99% probability that either is the father.

A single sperm has 37.5 MB of DNA information in it. That means an average ejaculation represents a data transfer of 1,500 terabytes.
