...in physiological textbooks, we speak of the brain, or the nervous system, as 'governing' the heart or the digestive tract, smuggling bad politics into science, as if the heart belonged to the brain rather than the brain to the heart or the stomach. Yet it is as true, or false, to say that the brain 'feeds itself'…
1. Fix your posture Research from Harvard shows that upright posture immediately signals confidence and competence. People literally perceive you differently within seconds. 2. Develop a resonant voice Studies consistently show deeper, well-modulated voices rank higher in attractiveness ratings for men. This isn't…
Herbert’s critique of this seemingly countercultural utopia is precisely aimed at its conservatism. In necessarily rendering life static, the utopian vision must deny the instability of signification and that permits for change and development itself. In making this argument, I am aware that I am (or Herbert is)…
Aristotle noted three characteristics of his concept of species. First, each species is a whole. It is comprehensive, representative of all the objects embraced within it, and any one of these objects may be used as an example of all others. The species tree, for example, embraces all trees whether they are used for…
In 2017, an AI system called Amper composed and produced original music for an album called I AM AI. The chord structures, instrumentation, and percussion were developed by Amper, which used initial parameters like genre, mood, and length to generate a full-length song in just a few minutes. Taryn Southern, a human…
Now, the other kind of stress Structural stress from activity that physical activity cause is structural stress. Now, when I was running this morning, for example, my mitochondria were generating all kinds of ATP to fuel my body, but my mitochondria were also spewing out all kinds of reactive oxygen species, which…
Humans of all to be much more physically active than our ape ancestors. Typical chimpanzee walks maybe two to three kilometers a day, and they take maybe what, three, 4,000 steps a day. A typical hunter-gatherer takes about 15 to 20,000 steps a day. Per kilo hunter-gatherers spend about twice as much energy per kilo…
What’s the difference between Bach and Darwin? Both were preternaturally gifted and widely known early in life. Both attained permanent fame posthumously. Where they differed was in their approach to the midlife fade. When Darwin fell behind as an innovator, he became despondent and depressed; his life ended in sad…
The concept of evolutionary traps has been used almost exclusively for studying how non-human species respond to cues in anthropogenic environments [24–34]. Key examples include artificial human lights attracting insects, island species responding naively to the presence of introduced predators, and seabirds not…
Humans are the most adaptable and ambitious people among the common races. They have widely varying tastes, morals, and customs in the many different lands where they have settled. When they settle, though, they stay: they build cities to last for the ages, and great kingdoms that can persist for long centuries. An…
The computer was suddenly revealed as palimpsest. The machine that is everywhere hailed as the very incarnation of the new had revealed itself to be not so new after all, but a series of skins, layer on layer, winding around the messy, evolving idea of the computing machine. Under Windows was DOS; under DOS, BASIC…
There are several kinds of speculation about the origins of play: (a) The first holds that play originates as a mutation and therefore an amelioration of dangerous adaptational conJicts. According to John Allman in Evolving Brains, this play mutation constitutes a pre-existing genetic function. (b) Some scholars claim…
A living being like you or me usually has two elements: a set of instructions that tell the system how to keep going and how to reproduce itself, and a mechanism to carry out the instructions. In biology, these two parts are called genes and metabolism. But it is worth emphasising that there need be nothing biological…
There’s a continuing struggle between complexity and robustness in both evolution and human design. A kind of survival imperative, whether in biology, engineering, or business requires that simple, fragile systems become more robust. But the mechanisms to increase robustness will in turn make the system considerably…
The more sophisticated and powerful a technology, the more people are needed to weaponize it. And the more people needed to weaponize it, the more societal controls work to defuse, or soften, or prevent harm from happening. I add one additional thought. Even if you had a budget to hire a team of scientists whose job…
Prolongation of Human Infancy.—-Nevertheless, as Professor Butler has recently pointed out, the doctrine of the prolongation of human infancy, which Professor John Fiske has so ably shown to be part of the theory of evolution, was anticipated by Anaximander of Miletus, who flourished about 565 b.c. Professor Butler’s…
When genes are activated, the instructions encoded within their DNA are first transcribed into a related molecule called RNA. Shepherd’s colleague Elissa Pastuzyn showed that the Arc shells can enclose RNA and move it from one neuron to another. And that’s basically what retroviruses do—they use protein shells to…
The currency of evolution is neither hunger nor pain, but rather copies of DNA helixes. Just as the economic success of a company is measured only by the number of dollars in its bank account, not by the happiness of its employees, so the evolutionary success of a species is measured by the number of copies of its…
Everything in the cosmos has a history. The old dichotomy between the "historical" sciences (like geology, paleontology and evolutionary biology) and the (for want of a better term) "functional" sciences (like physics and chemistry—some would call them the "real sciences") was always supposed to be that fields like…
If culture consisted simply of learning habits from others, it would soon stagnate. For culture to turn cumulative, ideas needed to meet and mate. The ‘cross-fertilisation of ideas’ is a cliché, but one with unintentional fecundity. ‘To create is to recombine’ said the molecular biologist François Jacob. Imagine if…
