Sense of propriety is unique to humans, cannot have origin from animals

Humans are endowed with conscience (con + science), come with in-built science of knowing what is RIGHT, WRONG and even PROPER. Animal has no such science—when it wants to cross road, it will simply cross risking traffic jam and danger to itself. When it feels hungry it would eat what sees whether or not it is own child. Here is a news report with picture from newscientist .com (October 13, 2017): “Male chimpanzee seen snatching seconds-old chimp and eating it.” Hence seeking origin of humans in animals is like seeking origin of dew in the core of sun.

Many humans may act with greed, thus take what belongs to others as they believe their origin is from animals. But this does not define humans as their very essence is being HUMANE—hence anyone acting inhumanely is addressed “You brute!” by fellow humans! This shows humans innately know their essence is to be HUMANE, to be compassionate, thus to act/react soft and sweet. They know what is wrong when wrong is done to them, hence know both right and wrong when they do to others.

They also know what is MORE THAN RIGHT which is called being PROPER. There are people who declined prestigious awards because they look also at track-record of the giver-country whether or not it has record of human rights violations. There are many "celebrities-who-declined-major-brand-endorsement" because such products do not contribute to well-being of users. One among them said accepting this lucrative offer for endorsing a fairness product "would be akin to insulting her beautiful dark-skinned sister." They do so because they do not think “It is right to receive right reward for the right work we they did.” Instead, they look from where such reward comes—are they HUMANE in their action and reactions!

This sense of PROPRIETY is shown in accepting/rejecting knowledge of others

People who see things along with what makes it function are soul-conscious persons as they see body and the force that makes it alive and function. When such a person sees division of species [one-sensed trees/plants, two-sensed worms, three-sensed insects, four-sensed reptiles, five-sensed fishes/birds/animals], he joyfully takes the lesson "If one-sensed trees/plants are such joyful servers giving us too valuable things yet taking only wastes from us, how much more I, the multi-sensed species, must do the same?” thus begins to enjoy life as dancer becomes the very dance. Such unselfish serving of one-sensed species is the signature-mannerism of the Great Director of this Drama of Life, and when it is imitated, greater freedom and happiness are experienced. This is the result of seeing also from where something originates.

In contrast,
when the body-conscious person sees such division of species would readily accept the conclusion of others that humans evolved from animals. It is like accepting the view of marriage from a divorcee and missing the joys of married life. Such people do not look from where that information is coming. Not only what is said, who said, his background etc are also important. After his foreign tours, Darwin "became a prematurely infirm recluse. Moreover, although his various illnesses were debilitating and he apparently suffered more pain than many mortals could have borne." (Google: Darwins-enigmatic-health, americanscientist .org). Darwin "had 10 children, but three died before age 10, two from infectious diseases. And three of the six surviving children with long-term marriages did not produce any offspring." (Google: "study-darwin-was-right-to-worry-that-marriage-to-his-cousin-affected-his-offsprin, news.osu.edu) He lived during a period when his religion was trying to have upper hand over Government which was also experimenting imperialism or trying to be fittest in the world. (Google: parliament .uk/living-heritage/overview/religionc19th).

Naturally his poor health and poor environment influenced his view of life which was easily accepted by people because of its hidden message GOD IS NOT NEEDED. But it did not make much headway in India because there word for atheist/materialist is Cārvāka which is a combination of cāru (good, beautiful) and vāka (discourse). (wisdomlib .org) It essentially means one who gives discourse pleasant to hear, like the Epicureans “Let us eat and drink as we will die tomorrow.” Scriptures too predicted "Last Days" will be characterized by such "ear-tickling myths" reducing everything to MAGIC of MATTER. They pleasantly accept even without doing simple calculation of population growth. If humans appeared millions of years ago—it would have spilled over into many, many universes because "Population of 1 Billion in 1804 became 8 Billion in 2022" (worldometers .info/world-population) which means it grew many times in 218 years.

What if Darwin was like Deepak Chopra doing yoga and meditation thus never fallen sick (Google "Deepak Chopra has never been sick Newyorker) we would have had a different world now with schools and colleges teaching also the science of mind-management with improvement lessons on IQ, EQ [Emotion Quotient] and SQ [Spirituality Quotient]. Then students that come out would not have shown anger and other negative emotions compulsively and impulsively, instead they would have been personification of joy and contentment discriminating between wrong-right-proper and knowing what to face/tolerate, what to cooperate/adapt with etc.
