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…
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…
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…
ABOUT 13.5 BILLION YEARS AGO, MATTER, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then…
Dery identified the parallels in "Black to the Future" as 'African Americans are, in a very real sense, the descendanmt of alien abductees," Dery writes. He compares the atrocities of racism experienced by blacks in the United States to "a sci-fi nightmare in which unseen but no less impassable force fields…
Civilisation, like life itself, has always been about capturing energy. That is to say, just as a successful species is one that converts the sun’s energy into offspring more rapidly than another species, so the same is true of a nation. Progressively, as the aeons passed, life as a whole has grown gradually more and…
THE MAGNA CORTICA ORIGINAL TENETS (DATE UNKNOWN BUT BEFORE BF 80) I. Self knowledge. Sapient beings have the right to know whether they’ve been mentally modified. II. Self-modification. Sapient beings have the right to pursue self-modification. III. Refusing modification. They also have the right to refuse it. IV…
As the epochs passed, the two species molded one another to form a well-integrated union. The little arachnoid, no bigger than a chimpanzee, rode in a snug hollow behind the great "fish's" skull, his back being stream-lined with the contours of the larger creature. The tentacles of the ichthyoid were specialized for…
Darwin’s concept of evolution is centered on natural selection, or survival of the fittest [1]. Although Darwin did realize that organisms possess structures and even entire organs that might not have an extant function, as is the case of rudiments [2], on the whole, selectionist thinking has heavily dominated the…
Physicists love to think about systems that take only a little information to describe. So when they get a system that takes a lot of information to describe, they use a trick called 'statistical mechanics', where you try to ignore most of this information and focus on a few especially important variables. For…
The singularity of the human species, 1 the study and defence of which form the plan of this work, stands out principally in the actual characteristics of what we shall call in these pages the Noosphere (or thinking envelope) of the earth. But just because, forming a true singularity (and not a simple irregularity) in…
Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits…
“You have a mismatched pair of genetic characteristics. Either alone would have been useful, would have aided the survival of your species. But the two together are lethal. It was only a matter of time before they destroyed you." [...] Jdahya made a rustling noise that could have been a sigh, but that did not seem to…
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…
at the end of the Pleistocene, certain human groups and their animal associates began progressively to show parallel reductions in size and stature, cranial gracilization, changes in post-cranial robusticity, shortening of the face and jaws, tooth crowding and malocclusion, and tooth-size reduction and simplification…
The study of domesticated animals since Darwin’s influential work (1868) has culminated in the formation of a set of changes that are claimed to distinguish domestic populations from wild species (for recent outlines of these see Price 1984, 1999; Hemmer 1990; Tchernov and Horwitz 1991; Hall 1993; Teichert 1993; Smith…
The fantasies of Wells and Huxley were based on the same idea, that a species adapting itself too perfectly to a static ecological niche is doomed to stagnation and ultimate extinction. Their nightmares describe a possible future for our species, if we succeed in building around ourselves a protective cocoon that…
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…
Life becomes different, and it carries on. Since the majority of invasive species are relatively benign, they add to an island’s overall biodiversity. The ecologist Dov Sax at Brown University in Rhode Island points out that non-native plants have doubled the botanical biodiversity of New Zealand – there are 2,104…
