Its not entirely clear how hes able to do it, but it appears hes processing what he sees on a different level to normal people. Herculano-Houzel S (2017) Numbers of neurons as biological correlates of cognitive capability. Despite being a weirdly specific question, this has been difficult to answer.

Not long is a good bet. We can even resolve to fight harder for that equality without denying that our ancestors would have railed against it, or worrying that only God can guarantee our beliefs that all humans are both equal and equally special. The cortical processing that finds patterns, infers conclusions, tells the good from the bad, remembers events, makes plans, changes plans as circumstances demandits all there. And because no single human can any longer hold in its brain all the knowledge accrued by our ancestors, we need as many brains as possible to be shaped by schooling, so that enough learn to make fire and pottery while others learn to cook meals for the masses or delicacies for the few; enough learn to make steel out of ore, while others learn to bend and assemble it into skyscrapers; enough learn to juggle the sound patterns that our tongues produce and weave their meanings into stories of where we came from and where we could go from here, and commit them to symbols that enough know to decipher back into meaning again; and enough learn to teach it all over again.

"I am become death, the destroyer of worlds." "It makes sense that the more neurons you have in the cortex, the longer it should take a species to reach that point where it's not only physiologically mature, but also mentally capable of being independent," Suzana Herculano-Houzel, author of the 2018 study and an associate professor of psychology at Vanderbilt University, said in a statement (opens in new tab). The more technologies to pass on, the more the teaching technologies neededthose systems and processes to transfer information systematically.

Lets say an asteroid or technological mishap wipes out 99.9 percent of humankind, and all of civilizations inorganic material achievements along with itcomputers, power lines, buildings, all of it. You dont even think of resorting to gas, because once reserves of gasoline are exhausted, getting fossil fuels out of the groundliterally getting the earth to spit black oilis now akin to doing magic. The Homo variety that invented cooking was already bipedal, with the advantage over knuckle-walking apes of consuming less energy to go the same distance, expanding the range of foraging and thus increasing the likelihood of finding food.4 The process of cooking builds on the very first technological implement: the stone tool, not simply a serendipitous rock splinter but an implement fashioned systematically to be handled, and that could be applied to cut meat from animals, crush bone, or pound roots.

But other than home appliances, electronic gadgets are mostly unworkable, because, well, there is no internet, and no news stations broadcasting signals, also from a shortage of able operators and power. The scientists found it so impressive that theyre now planning to implement it in existing prosthesis tech, meaning that prostheses could soon be better at the sense of touch than actual hands. Most of us do it every day without even thinking about it, yet talking is a uniquely human ability.

The list might be smaller than it once was, but there are some traits of ours that no other creature on Earth can match. What does pain look like in the brain, and how are new research findings leading to effective new treatments? Humans can adjust to new circumstances and learn from their errors. Time after time, people were more likely to reason that the only traits that would appear would be motor skills and emotionsnot cognitive skills, or "knowledge"even when the researchers made reference to real-world experiments that showed the contrary. harnessing motivation. Lieberman DE (2014) The story of the human body. Physically we are another primate, but our bigger brains are unusual. Fortunately, the experiment of taking technological achievements away to separate human abilities from biological capabilities does not have to be made, other than as mental exercises in dystopian science fiction. While we know we can touch and tell a lot about a wide variety of things, were never exactly told how advanced our sense of touch really is.

The seven million humans left on the planet, while a tiny fraction of what the species used to be, are still many more than the few hundreds of the endangered cheetahs or orangutans currently around. Her work has appeared in The New York Times, Scholastic, Popular Science and Spectrum, a site on autism research.
