"Not improbably, about two people out of every three are carriers of at least one serious recessive defect.”
Humanity, in other words, was not some genetically uniform stock that could be purged of a few defectives.

We humans can have the opportunity to get to know our parents. For microbes, that chance never comes, because their ancestors vanish—or, to put it another way, split into their daughter cells.

The word race seems to have first taken on a modern complexion during the Habsburg rule of Spain.

The strange stripes on apples—known as twin spotting—might occur because a cell had two copies of a gene for color. One copy might be a light variant, the other dark. When the cell divided, it accidentally bequeathed two dark variants to one daughter cell, and two light ones to the other. When those cells multiplied, their daughters would inherit those new combinations. And since they grew next to each other, the result would be dark and light stripes.
As geneticists studied these peculiar plants more carefully, they gave them a new name: mosaics.

With no place to call home, in 1648 Descartes got an extraordinary invitation. Christina, the queen of Sweden, asked him join her court and teach her philosophy. The twenty-two-year-old queen was a notorious freethinker who cursed regularly, read Virgil during mass, and combed her hair once a week. At first Descartes was reluctant to go, but the queen gradually charmed him. By the time Christina's warship arrived for him, Descartes was giddy. He put his hair in ringlets for the voyage and dressed in long pointed shoes and white fur-trimmed gloves.

Harvey trusted his own observations even when they didn't conform with Galen's (and despite the fact that any public disagreements with Galen could draw a fine). Galen claimed that human lungs have five lobes, but Harvey told his surgeons that they in fact had four. He tried to make his defiance as diplomatic as possible: „Perhaps in Galen's time it was common in man, whereas now it is rare,” he said.

[Willis] could persuade people to let him dismantle their dead husbands, wives, and children, and even disseced the bodies of aristocratic patients. For the first time in the history of medicine, Willis could link the diseases and the disorders that people experienced in life to the abnormalities he found in the brains after death. If he had been cutting open the brains of criminals, he could not have made the link so persuasively. His readers might have thought that the pathology he saw was just a sign of the low class of people from whom the brains came Because the brains belonged to England's ruling class, it became hard for his readers to dismiss his observations.

Neanderthals must have interbred with the modern humans who expanded out of Africa and would go on to settle across the Old World (that included the Europeans whom Osborn believed to be his beloved, pure Nordic race). Pääbo and his colleagues estimated that living non-Africans could trace 1 to 4 percent of their genetic ancestry to Neanderthals. There is thus more Neanderthal DNA on Earth today than when Neanderthals existed.

After the Korean War, South Korea’s economy rapidly grew to be the eleventh largest in the world, and the country established a universal health care system in 1977. North Korea, meanwhile, stagnated, channeling its income into nuclear weapons and its military while its population starved. South Koreans are now over an inch taller than North Koreans.
