Theories of Aging and a Stupid Female Biologist

Is using “stupid” and “female” in the same sentence redundant?

Re: “Myth” One – that hypothesis may be right or it may be wrong, but her “reasoning” is incomplete. What about natural selection, especially in the group selection context? Offspring may contain less genes of the parents than the parent themselves, but the offspring’s gene combinations may be better suited for being adaptive for the environment. On a single family basis, this may be a “wash” (parental genes may be better adapted), but consider the population as a whole.  Compare two populations: one immortal and the other mortal, each within a fixed territory with fixed carrying capacity. The immortal population – assuming they reproduce – will have parents eternally competing with offspring for limited resources, putting a cap on possible reproduction.  Indeed, this would degenerate into a generational struggle for fixed resources – leading the immortals to forgo reproduction or to not invest much in parenting.  This population would not have the genetic flexibility to be fit in changing environments.  The mortal population has each generation dying off, thus enhancing the fitness value of reproduction and parental investment.  This in turn creates a population in which generations succeed one another, allowing natural selection to work, producing a gene pool more flexible in adapting to changing environments.  Therefore, on a mass group level, a population with programmed mortality – which may actually just be a default program to slow down bodily maintenance after reproducing – will be more fit in adapting to changing environments than an immortal population that does not make room for new generations that have novel combinations of genes through sexual reproduction (independent assortment and crossing over).
By the way, isn’t it interesting these trash of the type like this “biologist” will invoke the importance of genetic similarity when it comes to parent vs. child, but will have a nervous breakdown if anyone applied the same reasoning to co-ethnic vs. alien?

Another Creative Genius Fail

Dumb Cochran.

Before defending Jews (*) as innocent and naïve waifs who foolishly actually believe in the extreme egalitarianism they preach to the Gentile rubes, the “creative genius” unburdens himself thus:

Considering that I have gone and on and about the lack of any built-in instinct to favor your own race, and explained why no such tendency is likely to evolve, I am hurt. But there is a simple solution to that.

Well, OK, that’s computer work.  What about Greg’s “real-life” examples?  Cherry picked?  Didn’t the Indians (dot, not feather) eventually work together to eject the British, for example?  Groups like Jews and Chinese are known to be high on ethnocentrism. Jews view themselves as akin to a race and there are more Chinese alive than all the Whites combined; Chinese are more or less a race as well.  And, certainly, East Asians living in other people’s nations have developed a very nice racial solidarity.

More to the point, contra Cochran and the rest of the HBD scum, IT DOES NOT REALLY MATTER.  As those of us with intellectual honesty (and common sense) have stated over and over again, the pursuit of ethnic genetic interests has nothing to do with the “evolution” of anything, but rather with rational thought mechanisms (that is beside the point that [evolved] ethnocentrism actually does exist, more in some groups than others; however, the fact remains that such innate ethnocentrism is not required for EGI).

But Cochran and the HBDers always either insinuate or openly state that “genetic interests cannot exist because we have not evolved X,Y,Z.”

They are frauds and liars, knocking down straw men.

But, let us turn it around.  Have humans evolved a preference for “high IQ” or any other of the ranked phenotypic traits so beloved of the HBDers?  Let’s look at the verdict of history, let us look at the experiment of real life!

Fact is, Greg, folks prefer dumb athletes, moronic celebrities, alpha male blowhard leaders, dark triad pick up artists, etc. over brainy scientists, academics, inventors, and HBD bloggers. That’s the evolved preference, from human evolution, to prefer the muscular hunter, the successful leader, the charismatic individual, the sexually attractive and successful, and to scorn the spindly brainy nerds unable to kill the mammoth, unable to inspire men into battle, and unable to excite the ardor of the opposite sex.

Folks prefer Babe Ruth over Albert Einstein, Kim Kardashian over Ruth Bader Ginsburg, Muhammed Ali over Bruce Lahn, Donald Trump over nebbish policy wonk Jeb Bush, and dim-witted and violent Negro athletes over balding and unattractive (and artery-clogged) New Mexican HBD bloggers.

That’s the way of the world, that’s our evolved preferences, so give it up Greg!  HBD is useless!  Who cares about IQ?

Oh wait, we will be told, we need to use rational thought mechanisms to decide what preferences are best, are most adaptive, and are better for us and for society, in the modern world.  Very good, very good.  Genetic continuity, including at the ethny level, is better for us in the modern world as well, you mendacious jackasses; in fact, genetic continuity is the very definition of biological adaptive fitness – more so than favoring some racial alien with a “high IQ.”

Once again, we are really getting tired of Cochran’s tiresome shtick as the “misanthropic, foul-mouthed, lovably ill-tempered creative genius.”  You’re boring Greg, a big YAWNfor you, and with increasing tribalism, the days of aracial HBD are numbered.  Unfortunately, the days of White survival are numbered as well, and the longer Whites waste time with the HBD cult, the less of a chance Whites have of out-living it.

Speaking of out-living: the unfortunate reality is that the wrong one died; in a just universe, Henry Harpending would still be alive and Greg Cochran would be the one dead. Well, it’s too late for the former, but we can still hold out hope for the latter.  How’s the ticker doing these days, Greggy?  Wouldn’t want you to get all worked up over at the blog you know.  Sudden heart attacks do happen, especially to those prone to them.  EGI Notes betting pool: who will drop dead first, Tricky Dick Lynn or Ticker Temper Cochran?  Dick is older, but Greg seems rather unhealthy.  Place your bets!

Rapid human evolution and Northeastern European autoimmunity.

Read here, excerpts, emphasis added:

Two studies presented at the Biology of Genomes meeting here last week show how our genomes have changed over centuries or decades, charting how since Roman times the British have evolved to be taller and fairer, and how just in the last generation the effect of a gene that favors cigarette smoking has dwindled in some groups
…With the help of giant genomic data sets, scientists can now track these evolutionary shifts in allele frequencies over short timescales….Pritchard’s team analyzed 3000 genomes collected as part of the UK10K sequencing project in the United Kingdom. For each allele of interest in each genome, Field calculated a “singleton density score” based on the density of nearby single, unique mutations. The more intense the selection on an allele, the faster it spreads, and the less time there is for singletons to accumulate near it. The approach can reveal selection over the past 100 generations, or about 2000 years.
Stanford graduate students Natalie Telis and Evan Boyle and postdoc Ziyue Gao found relatively few singletons near alleles that confer lactose tolerance—a trait that enables adults to digest milk—and that code for particular immune system receptors. Among the British, these alleles have evidently been highly selected and have spread rapidly. The team also found fewer singletons near alleles for blond hair and blue eyes, indicating that these traits, too, have rapidly spread over the past 2000 years, Field reported in his talk and on 7 May in the preprint server One evolutionary driver may have been Britain’s gloomy skies: Genes for fair hair also cause lighter skin color, which allows the body to make more vitamin D in conditions of scarce sunlight. Or sexual selection could have been at work, driven by a preference for blond mates…
…In a sign of the method’s power, Pritchard’s team also detected selection in traits controlled not by a single gene, but by tiny changes in hundreds of genes. Among them are height, head circumference in infants, and hip size in females—crucial for giving birth to those infants. By looking at the density of singletons flanking more than 4 million DNA differences, Pritchard’s team discovered that selection for all three traits occurred across the genome in recent millennia.
Joseph Pickrell, an evolutionary geneticist at the New York Genome Center in New York City, has used a different strategy to put selection under an even keener microscope, detecting signs of evolution on the scale of a human lifetime. He and Przeworski took a close look at the genomes of 60,000 people of European ancestry who had been genotyped by Kaiser Permanente in Northern California, and 150,000 people from a massive U.K. sequencing effort called the UK Biobank…
..In the parents’ generation, for example, the researchers saw a correlation between early death in men and the presence in their children (and therefore presumably in the parents) of a nicotine receptor allele that makes it harder to quit smoking. Many of the men who died young had reached adulthood in the United Kingdom in the 1950s, a time when many British men had a pack-a-day habit. In contrast, the allele’s frequency in women and in people from Northern California did not vary with age, presumably because fewer in these groups smoked heavily and the allele did not affect their survival. As smoking habits have changed, the pressure to weed out the allele has ceased, and its frequency is unchanged in younger men, Pickrell explains. “My guess is we are going to discover a lot of these gene-by-environment effects,” Przeworski says.
Indeed, Pickrell’s team detected other shifts. A set of gene variants associated with late-onset menstruation was more common in longer-lived women, suggesting it might help delay death. Pickrell also reported that the frequency of the ApoE4 allele, which is associated with Alzheimer’s disease, drops in older people because carriers died early. “We can detect selection on the shortest timeframe possible, an individual’s life span,” he says

Differences in gut microbes, particularly early in life, are likely to contribute to a person’s susceptibility to autoimmunity. Vatanen et al. explored this phenomenon by comparing the microbiomes of children from Finland, Estonia, and Russia from birth to 3 years old. Russians have lower incidences of autoimmunity than Finns and Estonians, and their microbiomes early in life differed, too, with Finnish and Estonian children harboring larger amounts of Bacteroides species. The primary source of bacterial lipopolysaccharide (LPS), an immunomodulatory molecule, also differed among the children. Bacteroides-derived LPS, which probably dominates in Finnish and Estonian children, did a poor job of teaching immune cells self-tolerance in cell culture and in mice, suggesting that it may contribute to autoimmune susceptibility in these populations.

Personality Variation and Group Selection

Food for thought.

The power of personality, by Elizabeth Pennisi, in Science 06 May 2016: Vol. 352, Issue 6286, pp. 644-647, DOI: 10.1126/science.352.6286.644

Excerpts, emphasis added:

As the existence of animal personalities becomes undeniable, researchers face a puzzle: how disparate personalities can coexist in a single species. Europe’s great tits are helping explain how. At long-term field sites in Germany, the United Kingdom, and the Netherlands, Niels Dingemanse, a behavioral ecologist at the Ludwig Maximilian University of Munich in Germany, and others have manipulated the number of offspring in nests and the density of nest sites. They’ve found that different conditions favor opposite personalities, thereby enabling behavioral variation to persist. 

When bird populations are dense, competition for territories, mates, and food sharpens, and one might expect aggressive individuals to win out. But when Dingemanse’s postdoc, Marion Nicolaus, tracked 541 adults for 4 years, recording which survived and how many young they produced, she found the opposite was true. It seems that when birds have to compete for scarce resources, the aggressive ones often get into fights, which take a physical toll. Aggressive birds also strain to keep all their young fed, further taxing their health. Thus, compared with more docile individuals, these birds are more likely to wear themselves out and fail to survive to the next breeding year. Only when densities are low do type A birds outcompete gentler ones and thrive, Dingemanse says. 

The findings parallel predictions made a decade ago about humans: that “in growing populations, competitive environments should favor shy, non-explorative, non-aggressive individuals,” Nicolaus, Dingemanse, and colleagues write in an upcoming paper in Ecology Letters.

One can correlate that to Frost’s “genetic pacification” theory and hypothesize that in high-density, populated, areas of higher civilization, more passive, gentle, and shy organisms are selected. Thus, the sissified pansy Whites, particularly those of the urbanized “Western” areas of the race – Western Europe and as well as the overseas Anglosphere. The negative effects of Christianity in selecting for passive faggotry would exacerbate this problem. 

By looking for marked fish, they found that shy individuals hadn’t simply moved out of the groups; they had vanished, most likely because they were not aggressive enough to compete for food in the group and had starved, or were too slow in reacting to predators that homed in on the school. On their own, however, the shy fish thrived, because remaining still is an effective antipredator defense. Bold fish, in contrast, became targets when isolated.

The finding suggests that personality types could play a role in evolution by helping divide a species into separate populations. Such segregation can lead to further differentiation and, eventually, to reproductive isolation. “That is often the first step in models of speciation,” Duckworth says.

Again, the same principles can apply to humans. Will more aggressive and ethnocentric Whites become ever more differentiated from sissified cucks, forming a new ethny with radical different behavioral and other phenotypes and the variant genetic architecture to match? Will the pansies be selected out, leaving the more ethnocentric to survive as the more fit? Or are these different types too integrated, with a too shallow behavioral gradient between them, so that both types will become extinct because of the mistakes of the numerous and influential cuck fraction?

Anelosimus studiosus, a small, brownish U.S. spider, lives in groups of from two to two dozen individuals and can build car-sized webs capable of snaring a small bird or mammal. Over the past decade, behavioral ecologist Jonathan Pruitt of UC Santa Barbara has determined that not only do individual spiders have personalities—bold and active or docile and inactive—but also that the mix of the two types gives each colony a distinctive “group personality.” The group personality needs to fit the demands of the local environment if the colony is to survive, he and his colleagues reported in Nature in 2014.

Thus, group selection based on different mixes of personality variants in the population. Does the same hold for humans? Continuing the speculation from above, do the cuck and ethnocentric fractions of the White population form an integrated whole, with the problem being we have too high a cuck fraction? Will a change toward more ethnocentrics (if possible) solve the problem without complete elimination of the cucks, or a “speciation” between the groups?

Science in the news.

Humans domesticating themselves.  Ideas similar to Frost’s genetic pacification.

Competition for niche space can promote evolution.

In recent years, biologists have increasingly recognized that evolutionary change can occur rapidly when natural selection is strong; thus, real-time studies of evolution can be used to test classic evolutionary hypotheses directly. One such hypothesis is that negative interactions between closely related species can drive phenotypic divergence. Such divergence is thought to be ubiquitous, though well-documented cases are surprisingly rare. On small islands in Florida, we found that the lizard Anolis carolinensis moved to higher perches following invasion by Anolis sagrei and, in response, adaptively evolved larger toepads after only 20 generations. These results illustrate that interspecific interactions between closely related species can drive evolutionary change on observable time scales.

One can speculate that this may apply to humans: negative interactions between different hominid subspecies (i.e., races) can promote evolution of particularly a native subspecies whose territory is invaded by a related subspecies.  The Third World invasion of the West may be stimulating rapid evolution of European human organisms.  The question is: in what direction? If the evolution has a “group selection” aspect, evolution may be in the direction of greater ethnocentrism.  However, a purely individualist selective pressure may actually select for even less ethnocentrism than even the feeble degree exhibited by extant Europeans.  Thus, on an individual level, short-term fitness may accrue by “throwing your race under the bus” so to speak, due to the massive incentivization of White dispossession described by KMacD at TOO. Whatever the case, Europeans are likely exposed to novel selective pressures due to the occupation of their territory by alien hominid forms.
