When Coke first went to China they picked a set of characters that sounded like "Coca-Cola." Turns out it meant "bite the wax tadpole." They now call it something which means "happiness in the mouth."
There's a liver fluke that hatches in cow dung, then is eaten by a snail. When it's a teenager it leaves the snail via slime trails, which ants will drink. The fluke then travels to a part of the ant's brain that allows it to actively control the ant. Every night it will take the ant to the top of a blade of grass and wait (if it did this during the day they'd both fry). Eventually the ant and fluke are eaten by a cow, and once in the cow's tract it'll lay eggs and start the process over.
The Spinx was carved out of a single solid block of sandstone using stone axes, copper chisels, and then rubbing sand on it for polish. Copper is VERY soft, so the chisels would need to be straightened and re-sharpened after about 20 blows. It would have taken 100 people 3 years to carve.
When you etch metal you submerge the metal in acid with some sort of stencil to block out what you want to remain raised (could be printed sheets of special paper, could be nail polish). If you have a thumbprint on the metal when you submerge it then that print WILL etch. The oils on your skin are a surprisingly effective block for the acid.
In ancient Egypt it was believed that the Pharaoh did not actually father any of his children. Amun-Ra would come down in the guise of the Pharaoh and impregnate the queen or concubine. Because of this royal lineage was traced through the mothers, since they were the only ones contributing DNA.
Despite popular belief, girls can be colorblind. The gene for it is recessive and is on the X chromosome, and nothing on the Y will cancel it out. So if a guy gets a gene on his X he has colorblindness. A girl has to have the gene on BOTH her X chromosomes so it doesn't happen as often, but it does happen.
The first clone, Dolly the sheep, was named that because the cells used were taken from the 'parent' sheep's mammary glands. The researchers called Dolly Parton, who has considerably mammaries, and asked if they could give the sheep her name. She though it was great and agreed.
Writing began because of the accountants. They needed some way to keep track of shipments.
Speaking of accountants, it took one to catch Al Capone. They didn't get him on the killing and the mob but they did get him for tax evasion.
