African Americans are the Descendants of Alien Abductees
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…
Argonauts: Magna Cortica
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…
Humans as Self-Domesticating Animals
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…
Attributes of Domesticated Animals
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…
Profiting on Asteroids
Some of the first questions which come up in any practical discussion of space colonization are questions of economics. Suppose we go out and settle on a convenient asteroid with our little spaceship, what do we do when we get there? How do we make a living? What can we expect to export in order to pay for necessary…
Brain Differences Between Sciences and Humanities
The areas of academic interest (sciences or humanities) and area of study have been known to be associated with a number of factors associated with autistic traits. However, despite the vast amount of literature on the psychological and physiological characteristics associated with faculty membership, brain structural…
The Importance of Altruism in Human Evolution
In proportion as physical characteristics become of less importance, mental and moral qualities will have an increasing importance to the well-being of the race. Capacity for acting in concert, for protection of food and shelter; sympathy, which leads all in turn to assist each other; the sense of right, which checks…
Why Marriage is Not Like Prostitution
What's more, most males could not possibly afford to buy a woman's reproductive potential if courtship were a simple economic exchange. What would be an appropriate market price for a nine-month pregnancy, the pain of childbirth, the exhaustion of breast-feeding, and twenty years of maternal care? At least half a…
Hamilton's Model
Hamilton's rule is rb - c > 0. Here c is the cost to the giver's fitness (c fewer offspring because of helping), and b is the benefit to the recipient's fitness (offspring gained by the recipient from the help). Here again, "r" is a measure of the relatedness between giver and the receiver [...] Hamilton’s rule says…
The Strategy of Releasing All Data
The response many organizations adopted then (and continue to pursue AF) is to provide overwhelming amounts of data to the public. This provided a two-fold defense. First, it allowed immediate deniability to any charge of withholding data. Second, the sheer volume of data available meant that almost any argument could…
Evolutionary Biology and the Punk Scene
Evolutionary biology historically has focused on a particular kind of change in heritable traits. Some traits enable an organism to have more offspring than other organisms in a population. In this way, a heritable trait can become more abundant in the next generation. It's a simiple numbers game. New traits appear…
Don't be Buffaloed by Elites
Don't be buffaloed by experts and elites. Experts often possess more data than judgment. Elites can become so inbred that they produce hemophiliacs who bleed to death as soon as they are nicked by the real world.
The Evolutionary Unit of Measurement
The starting point of Darwin's theory of evolution is precisely the existence of those differences between individual members of a race or species which morphologists for the most part rightly neglect. The first condition necessary, in order that any process of Natural Selection may begin among a race, or species, is…
Survival of the Fittest Doesn't Apply to Animals in a Social Group
Such biological ideas as the 'survival of the fittest,' whatever their doubtful value in natural science, are utterly useless in attempting to understand society ... The life of a man in society, while it is incidentally a biological fact, has characteristics that are not reducible to biology and must be explained in…
Animals that Marry
A large proportion of mankind, like pigeons and partridges, on reaching maturity, having passed through a period of playfulness or promiscuity, establish what they hope and expect will be a permanent and fertile mating relationship. This we call marriage.
Barriers that Keep Different Species from Interbreeding
What keeps members of two related species from mating with each other? There are many different reproductive barriers. Species might not interbreed simply because their mating or flowering seasons don’t overlap. Some corals, for example, reproduce only one night a year, spewing out masses of eggs and sperm into the…
The Biological Species Concept (BSC)
And when we think of why we feel that brown-eyed and blue-eyed humans, or Inuit and !Kung, are members of the same species, we realize that it’s because they can mate with each other and produce offspring that contain combinations of their genes. In other words, they belong to the same gene pool. When you ponder…
Mating Strategies of Males and Females
A vivid demonstration of this difference can be seen by looking up the record number of children sired by a human female versus a male. If you were to guess the maximum number of children that a woman could produce in a lifetime, you’d probably say around fifteen. Guess again. The Guinness Book of World Records gives…
Postmating Competition
Sexual selection doesn’t end with the sex act itself: males can continue to compete even after mating. In many species, females mate with more than one male over a short period of time. After a male inseminates a female, how can he prevent other males from fertilizing her and stealing his paternity? This postmating…
