CULTURAL QA 0R7202408
Topic-Humans based on Quora QA- Compiled
KR Quora has its own dictionary; Human means always immersed in the humour
of the members' minds.
Q1 What are some bitter truths about human nature?
KR Opening blast self-appraisal by Gopalkrishnan. Rachna who
observes Gopala’s avivekam. Why avivekam? Because even after reading the
venerated by himself only as the greatest does not change!!
Q2 How important is education?
KR 2nd blasted. Another self-pitying self-talking “OMG why did not
allow me a good education” sort of veiling cry, from Gopalakrishnan. GIGO;
what sent out comes back to him. Unfair world Gopala. And a despicable
liar too living in the foolish paradise?
Q3 Was there a time where we, as a species, almost went extinct?
G My note- After completion of a yuga, pralayam occurs and takes away
the lives of more than 90%. I Learned it in middle school class.
KR Never crossed the middle school as there was so much learnt
so many years were spent only there? As he learmt a lot but forgot as
Confucius said, he once again went back to that same middle school. This
TOBA is written nth time, even after telling the inconsistency of data as
reported.
What the world general body of national geography accepts
is:” The TOBA report, which encompasses the geological, climatic, and
genetic evidence related to the Toba eruption, is based on substantial
scientific research. However, it is not "perfectly true" in the sense that
there are still ongoing debates and uncertainties about the extent of its
impacts, particularly on human evolution. Science is an evolving field, and
as new evidence emerges, our understanding of events like the Toba eruption
may continue to be refined.” Hope Gopala hereafter will learn in that
middle school about TOBA.
The TOBA (Toba catastrophe) theory refers to a super volcanic
event that occurred about 74,000 years ago at the site of present-day Lake
Toba in Indonesia. The theory suggests that this eruption had significant
climatic and evolutionary impacts on Earth.
Scientific Basis and Evidence: Geological Evidence:
The eruption deposited a vast layer of volcanic ash, known as the Youngest
Toba Tuff, which can be traced across South Asia and the Indian Ocean.
Geological studies of this ash layer and the Toba caldera provide strong
evidence of the magnitude of the eruption. (KR only a limited conclusion
can be drawn but…). The theory posits that the eruption led to a volcanic
winter, causing a significant drop in global temperatures. Ice core data
from Greenland and Antarctica show signs of a cooling period around the
time of the eruption, supporting the theory of climatic impact. {KR Even
today in summer at Chennai, Dallas is cold and if someone were to say that
only SUN in Chennai causes the cold at Dallas?) Some proponents of the Toba
catastrophe theory argue that the eruption led to a genetic bottleneck in
human populations. Studies of mitochondrial DNA and Y-chromosome variations
suggest a reduction in human population sizes around this time, although
this evidence is still debated. {KR: ABSENCE OF EVIDENCE IS NOT LACK OF
EVIDEMCE; AND EVIDENCE OF ONE KIND MAY NOT PROVE ALL OFFENCES
SIMULTANEOUSLY}
Controversies and Debates:
While there is consensus that the Toba eruption was massive, the
extent of its climatic impact is still debated. Some models suggest a
severe volcanic winter, while *others propose more moderate effects. *The
idea that the Toba eruption caused a significant human population
bottleneck is controversial. Some geneticists argue that the evidence for a
bottleneck is not conclusive and could be attributed to *other
factors. *Archaeological
sites in India and other regions suggest that human populations survived
the eruption and continued their development, challenging the idea of a
near-extinction event. {KR I WROTE A LOT ON EVERY TIME GOPALA ERUPTED
WITH TOBA; BUT AS HIS MIDDLE SCHOLL (DOES HE MEAN NEDULLA OBLANGATA AS
MIDDLE SCHOOL AS BACK-MIDDLE?} >WHERE THIS LESSON WAS NOT TAUGHT FULLY?
{sorry friends I always said if he opens he gets back.}
Q4 What are some interesting things about the way the human
body is designed?
KR I sent a video yesterday and he had not seen it at all!! So only this
Q and A he could get only from the dinathanthi gossip columns.
G Because the brain is an elastic organ that can grow or expand around
the shape of the skull, experts have ruled out the possibility of this
tradition damaging a child's development. {KR IT WILL BE DENIED BUT YET
WILL BE GOSSIPPED AS IN DINA THANTHI. }
2 NOT ONLY IN ONE PLACE WHICH QUORA READ ALONG WITH G IN THE MIDDLE
SCHOOL BUT SEVERAL NATIONS; Head Elongation Practices: Cranial deformation
is a form of body modification in which the skull of a human being is
intentionally deformed. This practice has been carried out by various
cultures for aesthetic, cultural, or religious reasons. Examples of
Cultures Practicing Head Elongation:
The Mangbetu People of Central Africa: The Mangbetu, an ethnic group in the
Democratic Republic of Congo, are well-known for their practice of head
elongation. They used tightly wrapped cloth to shape the heads of infants,
resulting in an elongated skull. This practice was considered a sign of
beauty and intelligence.
The Maya and Other Mesoamerican Cultures: In ancient Mesoamerica, including
the Maya civilization, cranial deformation was a common practice. Infants'
heads were bound with boards or cloth to achieve the desired shape. This
was often associated with social status and beauty.
The Parachas Culture in Peru: The Parachas culture, which existed on the
southern coast of Peru, is known for the elongated skulls found in their
archaeological sites. These skulls were intentionally deformed using
binding techniques. The practice may have been related to social or
religious status.
The Huns and Other Eurasian Nomads: The Huns, along with other nomadic
tribes in Eurasia, practiced cranial deformation. The reasons for this
practice are not entirely clear, but it might have been related to cultural
identity and group affiliation.
Methods of Cranial Deformation
Binding: This method involves binding the head with cloth or other
materials to exert pressure on the skull, gradually altering its shape.
Boarding: Flat boards are placed on the front and back of an infant's head,
secured with bindings, to shape the skull as it grows.
Significance and Beliefs esthetics and Beauty: In many cultures, elongated
heads were considered a mark of beauty and nobility.
Social Status: Cranial deformation was often associated with higher social
status or royalty.
Spiritual and Religious Beliefs: Some cultures believed that altering the
shape of the head could bring individuals closer to the divine or enhance
spiritual abilities.
Cranial deformation, resulting in elongated heads, is a fascinating
practice observed in various cultures throughout history. It reflects the
diverse ways in which human societies have expressed identity, status, and
beauty. If you have a specific tribe or culture in mind, providing more
details can help in offering a more targeted explanation.

4 The plasticity of the human body is a fundamental aspect of its
ability to adapt, grow, and heal. This plasticity underlies many processes
in health, development, and recovery, making it a crucial concept in
understanding human biology and medicine. Whether through neuroplasticity,
developmental changes, physiological adaptations, or cellular responses,
the body's ability to change and adapt is a testament to its remarkable
resilience and versatility.
5 The term "plasticity" in the context of the human body refers to
its ability
to adapt and change in response to various stimuli. This concept is
critical in multiple fields, including neuroscience, developmental biology,
and physiology. Here are some key *aspects of the plastic nature of the
body (KR: NOT ONLY BRAIN THAT NEURON DO NOT CHANGE SHAPE BUT FINDS NEW
ROUTES TO FUNCTION WHICH TERMED AS PLASTICITY). How many kinds are there in
the small body itself?*
1 Neuroplasticity Neuroplasticity refers to the brain's ability to
reorganize itself by forming new neural connections throughout life. This
plasticity allows the brain to adapt to new experiences, learn new
information, and recover from injuries. Key features include:
2 Synaptic Plasticity Changes in the strength of synapses, the
connections between neurons, which are crucial for learning and memory.
3 Structural Plasticity Changes in the physical structure of the
brain, such as the growth of new neurons (neurogenesis) or the
reorganization of neural networks.
4 Functional Plasticity The brain's ability to shift functions from
damaged areas to undamaged areas, which is vital for recovery from brain
injuries.
5 Developmental Plasticity Developmental plasticity refers to the
body's ability to change during growth and development in response to
environmental conditions. This is especially prominent during critical
periods of development, such as infancy and adolescence. Examples include:
6 Bone Growth and Remodelling Bones can change shape and density in
response to physical stress and nutritional factors.
7 Muscle Development Muscles can grow and strengthen in response
to exercise and physical activity.
8 Hormonal Changes Hormonal levels can adjust in response to
developmental stages, influencing growth and bodily functions.
Physiological plasticity involves the body's ability to adapt to changes
in the environment or internal conditions. This includes:
Metabolic Adaptation: The body's ability to adjust its metabolism in
response to factors like diet, temperature, and physical activity.
Cardiovascular Plasticity: The ability of the cardiovascular system to
adapt to changes in activity levels, altitude, and other environmental
factors.
Immune System Adaptation: The immune system's capacity to recognize and
adapt to new pathogens, improving the body's defense mechanisms.
Cellular Plasticity
Cellular plasticity refers to the ability of cells to change their function
or identity in response to various signals. This is crucial in processes
like healing and regeneration. Examples include:
Stem Cell Differentiation: Stem cells can differentiate into various cell
types needed for growth, repair, and regeneration.
Cellular Adaptation to Stress: Cells can adjust their function and
structure to cope with stressors like toxins, radiation, and physical
injury.
Plasticity in Rehabilitation
Plasticity in rehabilitation is a concept widely used in medical and
therapeutic settings to enhance recovery from injuries and diseases.
Techniques that leverage plasticity include:
Physical Therapy: Exercises and interventions that promote muscle and joint
adaptation to regain function after injury.
Occupational Therapy: Activities designed to help individuals adapt to
daily tasks and improve their functional abilities.
Cognitive Rehabilitation: Techniques to help the brain recover from injury
or disease, often by creating new neural pathways.
VIRTUALLY SO MANY PLASTICITY DO EFFECTIVELY FUNCTION WITHIN 3 TO 6
FOOT HUMAN; SO, REEL GOSSIPERS SHAL WEIGH THEOPPONENTS WHO WITHOUT KNOWING
SO MANY, COULD NOT EXISTED IN SO MANY HIGH POSITIONS AND REMAIN COOL TODAY
AFTER RETIREMENT. Quora is for middle schools; group members are better
positioned to be offered the right information. KR IRS 8724
Q5 Is it possible that some (believed to be) extinct species of
humans like the Neanderthals are alive but we just don't know? Extinct
species do get found out to be alive sometimes.
KR As I had written in detail from Q1 to Q4 which lines of wrong
entry alone are being towed by Gopalakrishnan as he is still in the middle
school only.
\ The Toba volcano and out of Africa Anthropology
New Scientist 17th April, 2010 … had an interesting story on the
so-called Toba super volcano which blew its head on what is now Sumatra –
74,000 years ago.
Various articles appeared that seemed to suggest it was a massive
catastrophic event that almost wiped-out humanity from the face of the
earth – creating a genetic bottleneck in Africa.
*The severity of the Toba eruption was not actually based on reality
but on a series of computer simulations*. {KR Middle schools are not
expected to learn big things sirs} From these projections we learnt that
Toba released 2500 cubic km of magma and was 5000 times more powerful than
the 1980 eruption of Mt St Helens. It belched out 100 times more aerosols
that the recent eruption of Pinatubo in the Philippines and it was
suggested it caused global temperatures to drop by 10 degrees Celsius. This
set in motion a ten year long ‘volcanic winter’ and widespread catastrophe
as trees died and animals became extinct due to loss of habitat etc. Modern
humans, Homo sapiens, then thought to be confined to Africa, would have
been whittled down to a few refugia. After the event and as they regrew in
numbers, they may have sown the seeds of the genetic differences that we
now see between different races once they had left Africa.
It’s enough to give catastrophism a bad name and naturally the theory
has a number of detractors, not least being Hans Graf, an atmospheric
scientist at Cambridge University. He thought the climate change scenario
was grossly exaggerated – and suggested the magma produced was at least
half of that claimed, with the implication it was even less. He said it was
probably a giant in ‘ash’ production, nor sulphur, and said a lower figure
in temperature was appropriate – possibly a drop of 2.5 degrees.
The simulators were of course miffed with this slicing down of their
catastrophe but unfortunately for the computer modellers archaeologists and
geologists looking for evidence of the Toba event in India have come up
with evidence that would tend to support Graf. {KR I wrote ice age was a
farfetched idea in India, unlike Europe etc as Himalaya stood as a big
wall.} There is no evidence of a decline in woodlands but ash would have
spoiled water supplies, it is suggested, but most importantly a layer of
ash was NOT found. No skeletal remains, in contrast, were dug up but many
stone tools were found, in a layered stratum. A deposit that appears to
have been a camp and tool manufacturing site was buried under ash – but the
layer above the ash suggests that life went on much as before, and this
situation was found at more than one locale.
There has of course been spirited defense by the catastrophist camp – {KR
Like Quora and Gopala} and by the consensus opinion makers regarding human
origins, for if Toba was really not as powerful as the modelling portrayed
this will affect current ideas on human evolution and dispersal.
A lot depends on which species of humans made the tools found in
India. According to the consensus view humans did not arrive in India until
around 60,000 years ago. Before that date they are, or were thought to have
been confined to Africa in a pristine untouched environment where a pure
strain of humanity was eventually unleashed on the world – and quickly
colonised it. This position has been maintained even though there is
evidence of modern humans in the Levant as early as 125,000 years ago – but
this was countered by the claim that they were pushed back into Africa by
the succeeding Ice Age which was very dry, they think, in western Asia. At
the moment it is thought the tools were the product of an earlier species
of humanity such as Homo erectus – and that may well be right. Homo erectus
are *known to have been in India some 700,000 years (geochronology*).
However, the suspicion is that the tools were actually made by Homo
sapiens and this is throwing a brick into the consensus workings. It is
actually backed up by evidence from Australia which has been stuffed under
the carpet and marginalised simply because it did not fit into the
consensus model. Homo sapiens was in Australia by 60,000 years ago –
possibly even before that. At Kota Tampan in Malaysia a stone tool culture
has been found spanning the period between 74,000 and just 4000 years ago –
when it disappeared. {KR: Where so close an area, TOBA should have
annihilated all but….} This would seem to indicate the dispersal into the
Levant around 125,000 years ago was not a failure – as demanded by the
consensus model. Hence, it is quite reasonable to assume Homo sapiens
expanded during the last interglacial period reaching and colonising SE
Asia and Australia, migrating via India. However, the consensus model is
not beaten as it is now being suggested that the first wave of humans were
killed off by the Toba eruption – and the later dispersal, which came after
74,000 years ago, replaced them. It remains to be seen if this compromise
catches on or anthropologists cry foul. (KR Part 2 fowl to be contd later)
