• Is there an alternative scientific theory/hypothesis to evolutionary theory, for how the many species of plants and animals came to exist?

    I mean that is NOT based on religious/theistic accounts, but an actual scientific hypothesis/theory which has the potential to be falsifiable..

  • Why do humans kill each other?

    Best answer: I feel like it's an evolutionary thing. Waaay back in the day, humans had to constantly fight and kill predators to survive as well as hunt and kill prey so they could eat. As time went on and we evolved and progressed to the point we're at now, the need to fight and hunt for survival is gone. But I think... show more
    Best answer: I feel like it's an evolutionary thing. Waaay back in the day, humans had to constantly fight and kill predators to survive as well as hunt and kill prey so they could eat. As time went on and we evolved and progressed to the point we're at now, the need to fight and hunt for survival is gone. But I think that primal urge/instinct is still ingrained in us, and might be the reason we do things like boxing and UFC, fist fights, or things like lots of exercise or playing videogames, anything to get that rush of adrenaline or release of anger and stress.

    I think people that kill can't find their outlet, and so that urge/instinct hits a tipping point to where they explode and the end result is murder.

    If you're looking for more surface reasons:
    Anger
    Hate
    Money (hired or life insurance)
    To get out of marriage
    To hide an affair
    Gang initiation
    Drunk (usually with anger)
    High (altered state of mind)
    A lack of care/concern for others lives
    Ego
    Power
    Government (Army)
    Control
    Etc, etc.

  • Evolutionarily, why do we (most humans) find lizards scary (or, gross), when they can't really hurt us?

    Like, isn't that useless, to be scared or find lizards disgusting, if they can't really hurt us? Plus, they eat other insects that could hurt us..so they actually benefit us Don't say "I'm not scared of them"/"I don't find them gross". You *do* know that most others do...so... show more

  • In evolution what sort of factors would make an organisms life expectancy increase?

    Best answer: 1. Lack of predators either because there are no predators or because an animal is so big and strong or so well armored that few predators can eat it.Evolving armor or large body size would increase life expectancy. 2. Low metabolic rate. If the heart does not have to work as hard (beating a lot of times per... show more
    Best answer: 1. Lack of predators either because there are no predators or because an animal is so big and strong or so well armored that few predators can eat it.Evolving armor or large body size would increase life expectancy.

    2. Low metabolic rate. If the heart does not have to work as hard (beating a lot of times per minute) then an animal's life expectancy will increase. Lizards for example live longer than mice because lizard hearts do not have to beat as many times per minute. Similarly, elephants live longer than mice because elephant hearts beat a lot fewer times per minute.

    3. a favorable environment. No extremes in temperatures or humidity for example.

  • How could it be that my DNA test came back as '18 percent Chinese' when my entire family are not from, nor know of anyone being from China?

    Best answer: The world is full of mutts. I can remember back when I was a kid (I am 83) there were kids who would say, "I am a full blooded such and such." Probably their own parents didn't know who were all of their 8 great grandparents. Nations have invaded and occupied others and the original population... show more
    Best answer: The world is full of mutts. I can remember back when I was a kid (I am 83) there were kids who would say, "I am a full blooded such and such." Probably their own parents didn't know who were all of their 8 great grandparents. Nations have invaded and occupied others and the original population didn't get up and run away. Over time, they assimilated with the new comers. New nations have been created out of old nations. 18% can go back several generations. There are areas where the borders of China and Burma are attached. Persons from China could have immigrated to Burma and intermarried with some of your Burmese ancestors.

    They use Autosomal DNA along with Mitohondrial for the overall testing and Autosomal is not so simple. It is what most of your DNA is. You got it 50% from each of your parents but not 25% from each of your 4 grandparents. The reason why when your parents passed on Autosomal from their parents to you it went through "meoisis" where it was randomly jumbled and recombined. So you and your siblings got different chunks of Autosomal DNA from your parents. That means if you and a full sibling were tested by the same company at the same time, the results will not be exact. They don't explain this in their ads and promotions for the tests. Understand "meoisis" has been going on in your ancestry from the beginning. This means you might have an ancestry but not the DNA from that ancestry but your brothers or sisters can have the DNA.

    Another thing, the only thing companies can do is match you with population groups in their database and each company has its own database of population groups. Go to different companies and get different results. People ask us which is the best company to use and my reply is, it is the one that has the population groups that best match your ancestry and there is no way we or even you can know that. If you knew that much, why take the test.

    It has also been reported if you are tested by a company and go back sometime later and have them retest you, by that time they have received more populaiton groups that can alter your picture.

    The real value of genealogy DNA testing is if you are into traditional genealogy work using documents and records and the company you choose can detect from your DNA that probably some persons they have tested are related to you, maybe a few generations back, and they notify you of those people and you make contact with them, you can collaborate your information with them. They might have discovered ancestors and records you haven't and you might have discovered records and ancestors they haven't.

  • Is there any way to eat and drink the exact amount that you need and never have to used the bathroom ?

    Best answer: No. The human body converts food into fuel by (over-simply stated) burning (oxidizing) that food. The matter - the elements that make up the food - do not disappear when digested. The nutritious elements are utilized by the body but eventually excreted (typically in different form). The non-nutritious elements are... show more
    Best answer: No.
    The human body converts food into fuel by (over-simply stated) burning (oxidizing) that food.
    The matter - the elements that make up the food - do not disappear when digested. The nutritious elements are utilized by the body but eventually excreted (typically in different form). The non-nutritious elements are simple excreted.

    If this were not so, if what you imagine were so, then you would gain weight at the same amount that you ate food.
    For example: if an adult ate one pound of food per day (which is not a tremendous amount), then that adult would gain one pound in weight per day. After a year an adult would gain 365 pounds.

    So: because of the way our bodies work, both food and drink must be digested AND the byproducts excreted.

    Best answer: As long as you exercise the muscles, they will gain mass. Of course, weight bearing exercise is better. Lifting weights therefore is better than hitting the bag.
