    Think....in the slaughterhouse a whole cow is exsanguinated in just a few minutes after being slaughtered. It is hung upside down with its major neck arteries severed.

  • How were women dealing with periods when humans didn't created clothes yet?

    Best answer: Early humans did not wear clothes, so anything that comes out will not stick to clothing. Some of the discharges may stick to hair or skin. Animals lick their rear ends to keep that area clean. Humans cannot because we lack the flexibility. Instead we wipe it clean or wash it clean to keep flies from the area.

    Many internet articles are saying milk is bad and creating false claim such as "milk acidification take calcium from bones" although milk don't do that and the acidity of milk is low. Or claim like "Hormones in milk is killing you!" although it have very little to no effect when actually tested. And they start to claim correlation like "Country with higher milk consume rate have higher risk of osteoporosis so milk is bad for bones!" although there's no evidence milk have bad effect on bones and it's all just a coincidence. (Correlation doesn't mean Causation) Why do people hate on milk and try to make milk seems bad so much?

  • Did the first humans mate like animals do (male goes from behind) and how do living organisms just know what to do? Is it natural?

    Best answer: If you look at our closest relatives, the great apes (gorillas, chimps, bonobos and orangutan) we see that they do mate using a variety of positions, including face to face. Therefore humans did not invent the missionary position. As to how animals know how to mate, many animals do know what to do instinctively.... show more
    Best answer: If you look at our closest relatives, the great apes (gorillas, chimps, bonobos and orangutan) we see that they do mate using a variety of positions, including face to face. Therefore humans did not invent the missionary position. As to how animals know how to mate, many animals do know what to do instinctively. For example, no one teaches a frog, salamander, lizard, bird, worm, snake or mice as to what they should do to mate successfully.

    Human anatomy does have some features that help us in mating. For example, humans develop sexual desire as we approach puberty. Hair starts growing in the pubic area and in the armpits as we reach puberty. Breasts start to develop in females, and apocrine sweat glands start to develop in both genders. Apocrine sweat glands secret phermones that attract the opposite sex (except in some homosexuals that are attracted to phermones of the same sex for some unknown reason). Apocrine sweat glands are found in the armpit and pubic areas, where the hair in those areas help trap the phermones to make them linger a bit longer. Therefore our body is programmed in such a way that when we reach sexual maturity we are attracted by phermones to the pubic and armpit areas.

    At the same time, hormones give us a sex drive and some behavior, such as male thrusting of the body, are instinctive. Since humans are intelligent animals, we probably can figure out what to do to mate successfully using a combination of instinct and learned behavior, helped by phermones. Further, our parents can definitely teach us what to do. For example, a mother can tell a daughter what to do on wedding night and a father can talk to a son as to what to do with a woman when they have sex. Lastly, an experienced sex partner can also teach an inexperienced one as to what to do. For example, a female gorilla has been observed teaching a young male how to mate, even though the young male was not the silverback and both could have been in trouble if the silverback or dominant male were to see them mating.
