 Be Johann Sebastian Bach, not Charles Darwin

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 inactivity. When Bach fell behind, he reinvented himself as a master instructor. He died beloved, fulfilled, and—though less famous than he once had been—respe...

 Anthropocene Traps

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 being able to discriminate between the cues of marine plankton and marine plastics [34–36] (figure 1a). In the context of humans, evolutionary mismatch is a much more fr...

 How the Human's Short Lifespan Influences Their Behavior

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 individual human might have a relatively short life span, but a human nation or culture preserves traditions with origins far beyond the reach o f any single human’s memory....

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; and under them both the date of its origins recorded like a birth memory. Here was the very opposite of the authoritative, all-knowing system with its pretty screenful of icons. He...

 Evolutionary Origins of Play

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 the most fundamental conJict arises between dangerous and mutually threatening opponents. In studies of such conJicts, 80 percent of the time creatures from ants to mammals ac...

 Hawking Considers Computer Viruses Life

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 about them. For example, a computer virus is a program that will make copies of itself in the memory of a computer, and will transfer itself to other computers. Thus it fits the...

 Seeing Organizations as Biological Systems

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 more complex. Furthermore, that additional complexity brings with it its own unanticipated failure modes, which are corrected over time with additional robust mechanisms, which ...

 The Myth of the Solitary Villain

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 it was to develop a species-extinguishing bio weapon, or to take down the internet to zero, you probably still couldn’t do it. That’s because hundreds of thousands of man-year...

 Prolongation of Human Infancy

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 discovery, however, was itself anticipated by Burnet in his Early Greek Philosophy (95, p. 74) by a couple of years. Burnet, after quoting the Theophrastean account of the sp...

 Neurons Use Viruses to Share Information and Learn

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 protect their own RNA as it moves between cells in a host. So our neurons use a repurposed viral gene to transmit genetic information between each other in an oddly virus-like...
