Q3 Why is it so difficult for many people to grasp the concept of
evolution by means of natural selection and genetic mutation, even though
the evidence is overwhelming? A3 Claire Jordan, Degree in
biology and folklore; programmer, shop owner, secretary on newspaper Apr 8
*ible*. They think it means becoming human, or becoming some kind of ideal
form, or that one creature suddenly turns into or gives birth to a
different species. [This last can actually happen, as a result of a
chromosome mutation or a chance fertile hybridisation, but it’s very rare
and not how evolution normally works.
KR We can take the horse to the pond but never force it to drink.
Gopalkrishnan and Jordan are like that. Already long scientifically based
fallacies have been written here and yet if someone keeps on feeding wrong
data as if that is the truth, then he is yet to grow Full stop.
a6 Q5 What are some mind-blowing myths that sound like truth but
are actually false?
A5 Mark Rhysand, Anthropology Studies (2020–present)Apr 10
The Great Pyramid of Giza was built by slaves: While this is a commonly
held belief, it's actually not true. The workers who built the pyramids
were likely paid laborers who were well-fed and well-cared for.
KR: The Greek historian Herodotus tells us that the Great Pyramid was
built by 100,000 slaves who 'laboured constantly and were relieved every
three months by a fresh gang'. He is, however, wrong. King Khufu - 4th
Dynasty ruler of Egypt - the royal responsible for the commissioning of the
Great Pyramid, did not have a vast body of slaves at his disposal, and even
if he had, there was no way that 100,000 could work simultaneously on one
pyramid. (This was history till 1990 when Haus of Egypt showed nearby
tombs the thieves dug and heft as that of local labourers and decent ones
etc which analysis are rendered only by a few. So, whether myth or will
change facets are awaited. But Greece said so so Europe will accept it!!
And change of facts may not make the olde fact as Myth. It is not myth
blown but a change in thinking only from Egypt. But Cleo had lot of slaves
( we have seen in Benhur Cleo etc film) and what were they kept for?.
Slavery is also a myth?
Q Humans only have five senses: In fact, humans have many more than five
senses, including a sense of balance, a sense of temperature, and a sense
of time.
KR: WHAT ARE THE FIVE SENSES? AND HOW SENSE OF BALNCE, TEMO, AND BIOLOGICAL
TIME SENSE ETC ARE FELT? UPANISHADS HAD DESCRIBED THE 20 VARIATIONS SO
NICELY AND DID THE WRITER KNOW IT?
The subject neuro psychology says there are main and sun senses as:
The five basic sensory systems: 1. Visual 2.
Auditory 3. Olfactory (smell) System 4. Gustatory (taste)
System 5. Tactile System
The three sensory systems Ayres focused on in describing sensory
integration dysfunction: 5. Tactile System (see above) 6.
Vestibular (sense of head movement in space) System 7.
Proprioceptive (sensations from muscles and joints of body) System
Thus senses are only 5 sir other perceptions are through these 5 senses
only Half-baked knowledge is too dangerous because someone wrote it and
you did it back.
Q: Gum takes seven years to digest: This is a myth that's been around for
a long time, but it's not true. Gum passes through the digestive system in
the same way as other foods.
KR: If you swallow gum, it's true that your body can't digest it. But the
gum doesn't stay in your stomach. It moves relatively intact through your
digestive system and is excreted in your stool. NB: NOT AS ANY OTHER FOOD
BUT WITH STRAINS SUBJECT TO YOUR BODY CONDITIONS. “GIGO” IS RIGHT BUT HOW
HARD IS THE SUBJECT.
Q: Goldfish have a three-second memory: Goldfish actually have a memory
span of several months and are capable of learning and remembering things.
KR: The exciting impact of research on goldfish would be to rewrite the
biology textbooks about the place of fish in evolution as the starting
point for the development of a higher-functioning brain, in particular the
use of spatial cognition and this was found out by a 9-year-old girl. And
who said it has 3 seconds memory any records? It was written in the books.
Q: The Great Pacific Garbage Patch is a solid mass of trash: While the
Great Pacific Garbage Patch is a serious problem, it's not a solid mass of
trash. Instead, it's a collection of small pieces of plastic and other
debris.
KR: I do not understand as it is found out as mainly plastics but srtill
only names as “Once these plastics enter the gyre, they are unlikely to
leave the area until they degrade into smaller microplastics under the
effects of sun, waves and marine life. As more and more plastics are
discarded into the environment, microplastic concentration in the *Great
Pacific Garbage Patch * will only continue to increase.” Right sir it is
not termed as plastic because there are something more also.
Q Lightning never strikes the same place twice: This is a common myth, but
lightning can and does strike the same place multiple times.
Q Bats are blind: While bats use echolocation to navigate, they are not
blind and can see just fine.
Q The Earth is flat: This is a myth that has been around for centuries,
but it's been debunked by science. The Earth is a sphere.
KR: The last three are known to many of us long ago that they are true
and I do not know why included here? May be the posting is so older?
Q & G My note- Not fully sphere. In poles earth is oval, what I studied.
KR: No sir I had already written about it recently and so both Q & G are
erroneous.
Q: Carrots improve your eyesight: While carrots are a healthy food, they
don't actually improve your eyesight. This myth was perpetuated during
World War II as a way to hide the fact that the British were using radar to
spot enemy planes.
KR Sir Ladies finger and brain; Brinjal and bromine; so many are there;
so too carrot which is correct because,” Carrots contain beta-carotene, a
substance that the body converts to vitamin A, an important nutrient for
eye health. An extreme lack of vitamin A can cause blindness. Vitamin A can
prevent the formation of cataracts and macular degeneration, the world's
leading cause of blindness.”
Q: Sharks can smell a drop of blood from miles away: While sharks do have
a strong sense of smell, they can't smell a drop of blood from miles away.
The actual distance depends on factors such as the size of the drop and the
current in the water.
KR: Not exactly sir. They can also detect blood in the water from miles
away. Contrary to popular belief, however, sharks are not attracted to
human blood. A shark is more likely to be attracted to a bleeding fish or
sea lion than a human being with a cut in the ocean.{LOGGERHEAD MARINELIFE

a8 I laughed heartily as senseless gossip . Survival is the history of
humans. Child fell from the heights had survived than the human fall at a
short distance. Spinning yarn laughed so much.
A9 Please start from Bhartha varshaa Map sir This too I had provided
long ago KR IRS 16423
