• Is the idea of being "more evolved" a misunderstanding of evolution itself?

    I often hear this from people. However, the use of the word "more" in reference to evolution implies a subjective assumption. The assumption that evolution has a direction. Doesn't evolution simply state that all organisms are in a gradual state of transformation? Stating that something or someone... show more

Stating that something or someone is "more" evolved only shows the self-importance human beings have attached to themselves.

  • Does all glucose come from plants? Where else is it produced?

    Does all glucose come from plants? Where else is it produced?

    Best answer: Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.-- Sugar is made through photosynthesis by a chemical reaction within the plant’s cell. Photosynthesis takes place in the chloroplast of a cell.--Carbon, which makes up the most of the... show more
    Best answer: Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.-- Sugar is made through photosynthesis by a chemical reaction within the plant’s cell. Photosynthesis takes place in the chloroplast of a cell.--Carbon, which makes up the most of the rest of the plant, comes from the air and enters the plant through holes in its leaves. Oxygen from carbon dioxide, and hydrogen from water, enter through the leaves and roots, and are used to make glucose.

  • When a person is vaccinated, aren't they just being given the disease/illness that they're supposed to be protected from to build immunity?

    Why not just let the person build natural immunity? And some of these diseases, a person will never run into anyway?

  • From a science perspective, is there any logical reasons to live other than to reproduce & protect your offspring until they’re independent?

    Best answer: Nope, there is no "purpose" in life except to live long enough to reproduce. Since any individual that fails to reproduce (either because of bad genes or bad luck) will have its genes eliminated, the result is that all living organisms that are alive at any given point in time must have ancestors that... show more
    Best answer: Nope, there is no "purpose" in life except to live long enough to reproduce. Since any individual that fails to reproduce (either because of bad genes or bad luck) will have its genes eliminated, the result is that all living organisms that are alive at any given point in time must have ancestors that have the drive and the luck to reproduce successfully.

    It does not matter whether organisms that reproduce successfully performed anything useful or harmful in nature, their genes will live on only if they reproduce. Applying the same principle to humans, it does not matter whether a person has contributed to human kind by being a great scholar or philanthropist and therefore had a fulfilling life or one is just an illiterate bum, the only thing that counts is whether they left descendants or not. Mother Teresa and Sir Issac Newton contributed greatly to human society. They lived wonderful lives with good purposes, but since neither of them reproduced, their genes are lost forever. In contrast, an illiterate low wage worker who did nothing meaningful or purposeful (such as achieving "success") in his/her entire life will have his/her genes passed on to future generations. In terms of evolution, such a person is more successful that Sir Issac Newton and Mother Teresa.

  • From an evolutionary perspective, what is the purpose/origin of self-hatred and low self-esteem?

    These self-destructive emotions tend to bog people down and make them less attractive as well as less productive. Wouldn't these traits tend to have been bred out?

  • Is it true that cloning animals leads to 'high mortality rates' and diseases? how? evidence?

    I read article by the RSPCA where they claimed that cloning animals has high mortality rates, presumably in comparison to all other ways of breeding animals and also that diseases are more likely. I wonder where the evidence is for this, other than dolly the sheep living half her average breeds life span?

  • If a single neuron doesn't know what it is,how can the interaction of them or the whole brain understand what it is?

    Best answer: that is the big question, isn't it? There is a word for this, if I can remember it. Doesn't explain it, but does describe it, which is how the actions of many individuals leads to something that is more than the sum of the parts.

    Best answer: that is the big question, isn't it? There is a word for this, if I can remember it. Doesn't explain it, but does describe it, which is how the actions of many individuals leads to something that is more than the sum of the parts. Somehow, as a group, brain cells create something that none possess individually. like patterns formed by flocks of birds or schools of fish. Emergence, or emergent behavior, is the term. I knew if I waited it would pop up.

    But how? Well, lots of ideas but none seem very good to me, but that could be because this particular brain does not have the correct emergent behavior. Who knows? Possible Nobel Prize in there for the people who figure it out, perhaps?

    this gets very much into the problem of the essence of life, what is life, at the same time. Life is, on a functional process basis, just a bunch of chemical interactions, just as with non-life (although not in specific reactions), so how does it become self-aware or even if not aware, driven to self-preservation? There is more to the total than the sum of the parts.

  • How come our body is conscious while it's made of unconscious molecules and cells?

    Best answer: No one really knows what consciousness is or how it works. It might be that all matter does have a form of consciousness.
