  • Do any animals besides humans do food pairings?

    As eating a salad, I wondered if monkeys dip their bananas into ant hills or if bears carry their fish back to a favorite blueberry patch or if it is a purely human thing to do.

  • 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.

  • Why do Gorilla's have no hair on their chest and is their chest skin similar to black people skin?

    Best answer: Their chest is a product of evolution. Gorillas evolved from another species of ape that is closely related to the orangutan. There are 2 possibilities as to why their chest are different from those of other apes. One of these possibilities that it evolved by pure chance and it has no advantage. Scientists call such a possibility neutral genetic drift. The other possibility is that it is adaptive, meaning it is an advantage for the gorilla to have a chest like that.

    Gorillas are territorial and they beat their chest to create noise when they are excited. Such noises are louder than the noises the gorilla makes with their vocal cords. In contrast, the chimpanzee is capable of making a lot of loud noises with their vocal cords and the chimp does not beat its chest to produce sound. The orangutan does not beat its chest either, and it is not loud either. Therefore it appears that the gorilla evolved its chest so as to make noise, to compensate for its rather soft voice. The chest of the female gorilla is different as the skin appears to be less thick than the male's and they do not beat their chest.

    Therefore it would appear that the gorilla evolved a thick chest in the male so that they can make noise, and these noises likely serve as territorial signals. Other gorilla males that hear the noise know that there are territorial males nearby and a fight may happen if they try to go into the territory. Other animals that are territorial do it differently. They usually make sounds using their vocal cords, as most birds do by singing. Lions, tigers, leopards and jaguars roar to declare their territories. They are called roaring cats. Many other animals, such as crickets, do not have vocal cords, but they make noise by rubbing their body parts together. Animals will often declare territories using visual displays, such as the dewlaps of a lizard, if they cannot make any sounds.

    The gorilla's chest may lack hair because the hair would absorb some of the energy when the gorilla beats its chest, making the sound softer. Therefore if a mutation happens to make that area hairless, the sound can be louder. The louder sound is more advantageous because it can travel farther. That reduces the chance of another male unknowingly wanders into a male's territory and that means fights are less likely. Since fights can result in injury or even death, something that reduces the frequency of fights is advantageous, and this mutation can spread so that all male gorillas inherited this mutation that make their chest hairless.

    Humans did evolve from an ape, but our closest relative is the chimp, not the gorilla. Even though all non-Africans evolved from Africans who migrated out of Africa 60,000-70,000 years ago, there is no evidence that Africans beat their chest to declare territory. Instead, humans often have war chants, and national anthems. These vocal signals may serve to signal territorial ownership. Nevertheless, humans originally evolved in the African savanna, which has little food. Our ancestors were hunter gatherers and likely nomadic, since there is no reason to stay and defend a territory if there is little food within it. They may have to walk long distances and move from one place to another just to find food. Besides, we have a louder voice than gorillas, so we probably lost a chest that may be similar to that of the gorilla if our ancestor had one. Therefore Africans, even though their chest is hairless like that of the gorilla, do not have skin that is as thick as that of the gorilla. Besides, their entire body is hairless. Europeans and other more hairy humans likely re-evolved body hair because they are adapted to cold climates in ice age Europe and Asia. The increased amount of body hair comes at a price, as it is achieved by increasing the level of DHT in the body. DHT is a male hormone that stimulates hair growth but it also shrinks the hair follicle over long periods of time, so Europeans and some Asians often become prematurely bald. Premature baldness is rare among African males and their descendants. In fact higher levels of DHT often cause some European women to have excess facial and body hair (mostly in the legs and arms but not in the chest) and they also often suffer from fertility problems as the DHT may interfere with their reproductive organs,.

  • 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.

    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.
