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…
As our modern dinosaurs crash down around us, I sometimes wonder what kind of humans will eventually walk out of this epic transformation. Trump and the populism that’s rampaging around the world today, marked by xenophobia, racism, sexism, and rising inequality, is greatly amplified by the forces the GDE has…
Michael Dickmann: Here's what the story is. There was this little tadpole and a fish that grew up in a pond, and they were always intensely curious about life outside the pond. And then, eventually, the tadpole grows into a frog and discovers that, because he's an amphibian, he can go out and see what life is like. So…
"But the divine revenge overtook not long after those proud enterprises. For within less than the space of one hundred years, the great Atlantis was utterly lost and destroyed: not by a great earthquake, as your man saith; (for that whole tract is little subject to earthquakes;) but by a particular' deluge or…
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook…
We do not, we writers, represent mankind adequately. We do not think well of ourselves. We do not think amply about what we are. Essay after essay, book after book, maintain the usual thing about mass society, dehumanization, and the rest. How weary we are of them. How poorly they represent us. The pictures they offer…
The bombshell is that the Flynn Effect is almost certainly environmental. Natural selection has a speed limit measured in generations, but the Flynn Effect is measurable on the scale of decades and years. Flynn was also able to rule out increases in nutrition, overall health, and outbreeding (marrying outside one’s…
Or might the threatened animal be just one of several subspecies that all perform approximately the same ecological function? In that case its extinction might be inconsequential. That was the reality when the Galapagos giant tortoise ‘Lonesome George’ died in June 2012 and was mourned worldwide. Dubbed ‘the rarest…
I asked Rooney about the remarkable ability of deer to thrive in their home range—most of the U.S.—while producing ecosystem simplification and a biodiversity crash. In his own studies of deer habitats in Wisconsin, Rooney found that only a few types of grass thrive under a deer-dominant regime. The rest, amounting to…
To end on a more cheerful note, I think I have found a fallacy or two in some of the more spectacular arguments used by the Insect Age enthusiasts when they are hardest pressed. For one thing, the fact that insects as a class are 300,000,000 years old, if it is a fact, while we have been here only about 1,000,000…
I don't doubt that Aristotle thought more in actual footage during his life than any other person ever thought in the same elapsed time of sixty-two years. I do say, however, that any prize he deserves for so doing should be for quantity, not quality, as a great deal of it was spinach. He would sit around and think…
There are three principal obstacles to be overcome in adapting a terrestrial species to life in space. It must learn to live and be happy in zero-g, zero-T, and zero-P, that is to say, zero-gravity, zero-temperature, and zero-pressure. Of these, zero-g is probably the easiest to cope with, although we are still…
Dwellers were almost everywhere and had been there practically for ever. They had learned a few things about making war over that time, and while their war machines were believed to be as customarily unreliable - and eccentrically designed, built and maintained - as every other piece of technology they deigned to…
IDIC basically states that we should delight in the differences amongst people, not hate people because they are different. It seems that the human race has found a large number of ways to hate (different sex, color, religion, nationality, political party, social class, etc) and has emphasized hate over co-operation…
In the beginning was the singularity, and the singularity was infinitely dense and infinitely hot, And the singularity expanded and the singularity cooled and there was chaos, And of the primeval atom was born the Universe. And the Universe was matter and antimatter, and baryogenesis was violated and matter…
We are survival machines, but 'we' does not mean just people. It embraces all animals, plants, bacteria, and viruses. The total number of survival machines on earth is very difficult to count and even the total number of species is unknown. Taking just insects alone, the number of living species has been estimated at…
Now let us examine more closely what we know scientifically about extinction. At the annual Congress of the American Association for the Advancement of Science, as held approximately ten years ago in Philadelphia, two papers were presented in widely-separated parts of the Congress. One was presented in anthropology…
What is a person? This seems like an easy question, but appearances can be deceiving. Throughout the long sweep of human history, the answer to the question of what a person is has continually changed. Was a woman a person, or was she a piece of property? Or was she even a liability, something that had to be…
evolution conserves things that work. We have a conserved brain, with different ages for its different parts—in effect lizard at back and bottom, mammal in the middle, human at the front and top. Lizard brain to breathe and sleep, mammal brain to form packs, human brain to think it over
pathological aggression: dolphins kill porpoises for no reason, they don’t eat them, they’re not competitors. Does this suggest the uncanny valley exists for all mammals?
