CULTURAL QA 06202401 Q1 Was there a time where we, as a species, almost went extinct?
Q Ung-Jin Kim,Former Biologist, Director of Human Genome Center at California Institute of Technology (Caltech) (1989–2019)Updated Mar 29 KR He is revealing a theory; just a theory that is supposed to have occurred in the volcanic belt even today in Indonesia, scattering all over the ashes. Yet even the world of science had not made it absolute. The fault of misunderstanding as an answer rendered, squarely lies over the wrong reader and reporting. All over the web sites TOBA is there. The truth and the lies about Toba eruption and extinction theory The Toba eruption and its potential role in human evolution and extinction is a topic that has generated significant scientific debate and *speculation.* Here's an overview of some of the truths and misconceptions surrounding the Toba eruption and its connection to extinction theories: Truths: Toba Eruption: The Toba eruption occurred approximately 74,000 years ago on the island of Sumatra, Indonesia. It was one of the largest volcanic eruptions in the last two million years, with a Volcanic Explosivity Index (VEI) of 8, making it a super-eruption. Climate Impact: The eruption likely had significant global climate effects, including a temporary cooling of the Earth's climate due to the release of large amounts of ash, sulphur dioxide, and other gases into the atmosphere. This *could have* led to a volcanic winter, affecting global temperatures and weather patterns for several years. Genetic Bottleneck: *Some *genetic evidence suggests a *significant* reduction in human population size around the time of the Toba eruption, leading to the hypothesis of a genetic bottleneck. This idea proposes that the eruption *may have led to* a severe reduction in the human population, potentially affecting the genetic diversity of Homo sapiens. Misconceptions: Extinction Event: While the Toba eruption is often cited as a potential cause of a human population bottleneck, there is ongoing debate among scientists about its actual impact on human populations and whether it led to a near-extinction event. Some studies suggest that human populations may have been resilient and adaptable enough to survive the climatic effects of the eruption. Sole Cause of Extinction: The Toba eruption is unlikely to have been the sole cause of any extinction event, including the extinction of other hominin species such as Homo erectus or Homo neanderthalensis. Multiple factors, including climate change, competition with other species, and human behavioural adaptations, likely played roles in the extinction of various species. Impact on Evolution: While the Toba eruption may have had some impact on human populations and genetic diversity, its precise role in human evolution is still uncertain. Some researchers propose that the eruption may have influenced human migration patterns or cultural developments, but direct evidence for these hypotheses is limited. In summary, the Toba eruption was a significant volcanic event with potential global climate impacts, but its exact role in human evolution and extinction remains a subject of ongoing scientific investigation and debate. It's essential to critically evaluate the evidence and consider multiple factors when discussing the Toba eruption and its implications for human history. It is also written in a similar frame, if so, why such Q and A at all? It is spoken as if Amazon Forest is cropped up. On the contrary we have our scriptures narrating the evolution and involutions explained as Srishti, Stuthi and Samharam. Think before you ink please. Q2 What happens when you don't put your phone on airplane mode on an airplane, and you use the wifi? KR Another waste Q and A. Any phone will not show the welcome message in each halt sir; international roaming access must be there. Suppose you are using only BSNL, it will not show any welcome message other than Chennai for example. Q is PURPOSE OF AIRPLANE MODE. Airplane mode is a feature found on most smartphones and other electronic devices that disables their wireless communication abilities. Its primary purpose is to ensure that electronic devices comply with airline regulations during flights. Here are some specific reasons for using airplane mode: Airplane mode prevents electronic devices from *emitting radio frequency signals that could potentially interfere with aircraft communication* *and navigation systems*. This interference could disrupt important flight operations and compromise safety. Many airlines and aviation authorities require passengers to switch their electronic devices to airplane mode during take-off and landing and throughout the flight. This requirement is intended to minimize the risk of interference and ensure compliance with safety regulations. (Tower communication to plane interruptions). Disabling wireless connections in airplane mode can help conserve battery life, as the device no longer actively searches for cellular networks, Wi-Fi signals, or Bluetooth connections. This can be particularly useful during long flights when access to charging outlets may be limited. Airplane mode can also serve as a way to reduce distractions and promote a quiet and focused environment during flights. By disabling incoming calls, messages, and notifications, passengers can enjoy uninterrupted time for work, reading, or relaxation. When traveling internationally, using airplane mode can prevent roaming charges from cellular networks in foreign countries. By disabling cellular connections, users can avoid unexpected fees for data usage or phone calls while abroad. Q3 Does money make you happy? KR It does not depend; it is not making anyone happy if it overflows. All our Vedas do teach us only that which alone I had been writing; nd after reading all a Q and A that too with a response of an ignorant asked to portray an aanmeekam guru? Q The evidence has changed a lot in the last 10–15 years. KR Evidence of happiness in 2009 and not now? So many rishis lied? Q Before the financial crisis, many studies showed increased happiness until you hit mid-income, then it stagnated. KR: Which country's answer is this? Financial crisis? USA or India? Q Seems common sense. If you only eat rice daily and become middle-class, it improves your health, wealth, and everything else if you use it correctly. KR Money only to eat rice and rice keeps oneself in health? Q However, what difference does it make once you are at `that level`? The difference between $60,000 and $600,000 is just more choices - a 5-star hotel instead of a 4-star or earlier retirement if you are frugal - hardly life-changing. KR See he teaches Americans and you whom as if unknown; even at USA not now. $600000 can afford 5 star but 60000 can never access 4star every time. Q However, the financial crisis led many economists to change their minds, as even the relatively small declines in income seen in developed countries (often 5%-10%) resulted in more unhappiness. KR USA is ridden with mania crisis so they join YOGA and Isckons as LIFE OF THEIR WEDDING, OFFICE ETC ARE NOT GOOD. Happiness is within and if I talk to them that line, they are surprised. IMMATURED BRAINS have only a mundane thought. Q I tend to think that it is more because of anxiety about the future than the money itself. KR Even a maniac owns a car so it is not without money;but psychological upsets of control og their freedom, though appearances of freedom are created. Q So it depends on how you use money. KR Also incoming with a purpose Q If you use money to do these things, it is unlikely to make you happy: You use the money to try to impress people you don't even like on Instagram! Over-consumption. You are wealthy but don't have your health. You get sick chasing money! But using money in this way may help: You use the money to travel. That, in turn, gives you memorable experiences. Recently, I went on an African safari via this company - Customized, Luxury, African Safaris (I have no affiliation with them apart from being a happy customer). The experience sure beat spending money on physical things! 2. Pursue your passions 3. Support charities you love 4. You use the money to help family and friends 5. You have enough money to have financial freedom The last point is key. Money shouldn’t be about numbers on a screen. It should be having options and freedom. KR The outlook of US citizens is a confided thinking; thence they look into India for mental Balance and stability, xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Q4 What can Brahmins do to stop or reduce the Brahmin bashing? KR Leave one sect; IS THERE BASHING ON THIS EARTH; IF YES BRAHMIN IS ALSO ONE AMONG THEM. IF NOT, IT IS A LIE. The Mylapore incident was rare; and all Brahmins cannot be said as bashed up. Then why all Brahmins vote DMK then? After all, bashing within a group is escalated by the author himself which is scattered all over in the decades. We are not bashed up. We are shifting our gear. And we are not afraid of the intenders. If at all we can file a case in the court that we are not Brahmin by caste, even the irregular distribution will stop. LET US BE BRAHMINS BY VARNA AND NOT AS CASTE.
