发帖数: 4184 | 1 Leftist Lies Destroyed as Scientists Discover the Gene Which Causes Brain
Size and Intelligence
JULY 31, 2013 BY TNO STAFF— IN SCIENCE
Nearly 100 years of leftist lies and deception, which has claimed that
intelligence is not genetic, has been destroyed by the science of genetics.
According to a new study, just published in the University of California Los
Angeles (UCLA) newsroom, scientists have definitively found the genes which
control brain size and intelligence.
Even worse for liberals, dozens of studies have found race differences in
brain size,whether measured by MRI, endocranial volume, brain weight at
autopsy, or external head size (with or without corrections for body size).
Most were carried out on the three major races of East Asians, Europeans,
and Africans. Averaging all the data, the following figures have emerged:
Brain size average for East Asians = 1364cm3; Whites = 1347cm3; and Blacks =
1267cm3.
The overall mean for East Asians was 17cm3 more than for Whites and 97cm3
more than for Blacks.
Since every cubic centimeter of brain tissue contains millions of brain
cells and billions of synapses, the race differences in brain size help to
explain the race differences in IQ.
The latest overview, billed as the “world’s largest brain study to date,”
saw a team of more than 200 scientists from 100 institutions worldwide
collaborate to map the human genes that boost or sabotage the brain’s
resistance to a variety of mental illnesses and Alzheimer’s disease.
Additionally, the study (also published in the journal Nature Genetics),
found new genes which control “differences in brain size and intelligence.”
“We searched for two things in this study,” said senior author Paul
Thompson, professor of neurology at the David Geffen School of Medicine at
UCLA and a member of the UCLA Laboratory of Neuro Imaging.
“We hunted for genes that increase your risk for a single disease that your
children can inherit. We also looked for factors that cause tissue atrophy
and reduce brain size, which is a biological marker for disorders like
schizophrenia, bipolar disorder, depression, Alzheimer’s disease and
dementia.”
Three years ago, Thompson’s lab partnered with geneticists Nick Martin and
Margaret Wright at the Queensland Institute for Medical Research in Brisbane
, Australia, and with geneticist Barbara Franke of Radboud University
Nijmegen Medical Centre in the Netherlands.
The four investigators recruited brain-imaging labs around the world to pool
their brain scans and genomic data, and Project ENIGMA (Enhancing Neuro
Imaging Genetics through Meta-Analysis) was born.
“Our individual centers couldn’t review enough brain scans to obtain
definitive results,” said Thompson, who is also a professor of psychiatry
at the Semel Institute for Neuroscience and Human Behavior at UCLA.
“By sharing our data with Project ENIGMA, we created a sample large enough
to reveal clear patterns in genetic variation and show how these changes
physically alter the brain.”
In the past, neuroscientists screened the genomes of people suffering from a
specific brain disease and combed their DNA to uncover a common variant.
In this study, Project ENIGMA researchers measured the size of the brain and
its memory centers in thousands of MRI images from 21,151 healthy people
while simultaneously screening their DNA.
“Earlier studies have uncovered risk genes for common diseases, yet it’s
not always understood how these genes affect the brain,” Thompson said.
“This led our team to screen brain scans worldwide for genes that directly
harm or protect the brain.”
In poring over the data, Project ENIGMA researchers explored whether any
genetic variations correlated to brain size.
Project ENIGMA investigators also discovered genes that explain individual
differences in intelligence. They found that a variant in a gene called
HMGA2 affected brain size, as well as a person’s intelligence.
DNA comprises four bases: A (adenine), C (cytosine), T (thymine) and G (
guanine). People whose HMGA2 gene held a letter “C” instead of a “T” at
a specific location on the gene possessed larger brains and scored more
highly on standardized IQ tests.
“This is a really exciting discovery, that a single letter change leads to
a bigger brain,” Thompson said.
“We found fairly unequivocal proof supporting a genetic link to brain
function and intelligence. For the first time, we have watertight evidence
of how these genes affect the brain.”

脑子小上大学也没用啊
左逼们把一大堆核桃仁黑魔三送去读大学这是浪费社会资源
最后效果很差
还不如让他们去干点体力劳动对社会贡献更大
可惜左逼装逼成性
非要硬拗自然规律
结果就是整个社会价值观被破坏，混乱无比

发帖数: 10729 | 9 如果“对智力较低的人降低标准才是公平的”，那么相应的降低他们的生活标准也将是
公平的（因为智力低，要求不高）。这岂不是给以前的种族隔离找借口？
竞选总统，州长，法官，到BUSDRIVER,PILOTS,是不是也应该根据不同人的智力、体力
，调节标准。
希望我们会有幸得到一个从智商50～60群体中选出来的总统。
谁会选择搭乘智商50～60群体选拔出来的飞行员开的飞机？ | Z*****l
