The 10000 Year Explosion Quotes

“Biology keeps culture on a leash, which is why you can’t teach a dog to play poker, never mind all those lying paintings.”
― Gregory Cochran, The 10,000 Year Explosion: How Civilization Accelerated Human Evolution

“The motto here is that sometimes the apparently inferior choice has a better upgrade path: Evolution can’t know this, and we aren’t particularly good at recognizing it ourselves. On the genetic level, it translates as follows: Natural selection may solve the same problems differently in different populations, and what appears to be the most elegant solution at the time may not in fact turn out to be the one that works best in the long run. The seemingly inferior choice”

“Probably the most popular and attractive hypothesis is that modern humans had developed advanced language capabilities and therefore were able to talk the Neanderthals to death. This idea has a lot going for it. It’s easy to imagine ways in which superior language abilities could have conferred advantages, particularly at the level of the band or tribe. For example, hunter-gatherers today are well known for having a deep knowledge of the local landscape and of the appearance and properties of many local plants and animals. This includes knowledge of rare but important events that happened more than a human lifetime ago, which may have been particularly important in the unstable climate of the Ice Age. It is hard to see how that kind of information transmission across generations would be possible in the absence of sophisticated language. Without it, there may have been distinct limits on cultural complexity, which, among other things, would have meant limits on the sophistica- tion of tools and weapons.”

“In an extreme example, the Russian scientist Dmitri Belyaev succeeded in developing a domesticated fox in only forty years.5 In each generation he selected for tameness (and only tame- ness); this eventually resulted in foxes that were friendly and enjoyed human contact, in strong contrast to wild foxes. This strain of tame foxes also changed in other ways: Their coat color lightened, their skulls became rounder, and some of them were born with floppy ears. It seems that some of the genes influenc- ing behavior (tameness in this case) also affect other traits—so when Belyaev selected for tameness, he automatically got changes in those other traits as well. Many of these changes have occurred as side effects of domestication in a number of species—possibly including humans, as we shall see.”

“Jewish intellectual prominence is striking. As we have said, Ashkenazi Jews are vastly overrepresented in science. Their numbers among prominent scientists are roughly ten times greater than you’d expect from their share of the population in the United States and Europe. Over the past two generations they have won more than a quarter of all Nobel science prizes, although they make up less than one-six-hundredth of the world’s population. Although they represent less than 3 percent of the U.S. population, they won 27 percent of the U.S. Nobel Prizes in science during that period3 and 25 percent of the A. M. Turing Awards (given annually by the Association for Computing Machinery).4 Ashkenazi Jews account for half of twentieth-century world chess champions. American Jews are also overrepresented in other areas, such as business (where they account for about a fifth of CEOs5) and academia (where they make up about 22 percent of Ivy League students6). Although”

“The sphingolipid mutations, in particular, have effects that could plausibly boost intelligence. In each, there is a buildup of some particular sphingolipid, a class of modified fat molecules that play a role in signal transmission and are especially common in neural tissues. Researchers have determined that elevated levels of those sphingolipids cause the growth of more connections among neurons, the basic cells of the central nervous system (see page 221).”
