About Evolution

  1. Dec 17, 2005 #1
    Humans have a big influence on the evolution process of many species. Do you think they should? Is this fair?

    Are you looking for biological answer?

    I have the feeling that the question is more in realm of philosophy and ethics rather biology.

    Biologically speaking, most species affect each other's evolutionary course. Animals will evolve features to escape/evade predators, catch prey, compete for sparse food/space etc. What Humans are doing is little different. Survival of the fittest, etc.

    Ethically, its a different matter...

    if you are asking if we should or shouldn't impose our existence so dis-respectfully and wantonly, then you will get many varying responses.

    is it fair? no. is it responsible? no. is it short-sighted and ignorant? for sure. is it stupidity? absolutely.
    we screw ourselves up, too. that's what's so absurd about it.

    I just do not understand the logic of this question. :confused: What you ask is, "is it fair for humans to live the life of Homo sapiens". Humans eat animals, they compete with animals because humans are animals--biologically speaking. All animals (and plants) serve as cause to effect evolution of other forms of life. If we are to discuss what is fair as to human actions, let us ask if mans inhumanity to man is fair.

    okay thanks for replying everyone... I guess the question is more ethical... In a biological sense, it's all about survival, but its not like humans are only JUST survivng. They are impacting the course of evolution for many species but its not necessary (for pure survival).

    What i'm trying to ask is what everyone thinks about this, is it ok or not?

    Its impossible not to affect the world around, just as it affects us. There are no ethics to it, it simply is and cannot be avoided. We are part of nature, and it is part of us, so the question is invalid.

    if humans are "part and parcel" of nature, why do we try to seperate ourselves from it? why do we destroy it? why do we shun it and try to conquer it? is it for our own glorification?

    the question is certainly a valid one.

    The answer is "religion" that holds that Reality is a transcendential ideal. In history, many peoples had religion based on objective Reality (nature). When one forms a philosophy that says objective Reality does not exist, then by definition nature does not exist, thus let us spit on it.

    Rational self-interest does not preclude the consideration of our impact upon the environment. Failure to consider whether our actions have a negative impact on our environment can have a negative impact on ourselves as a consequence. In this way nature maintains a balance between our existence and the well-being of the world we live in. It is in our own best interest that we take care of the world in which we live.

    for sure...

    In the sense of evolution, our own self interest is irrelevant.

    The recurring mistake in viewing evolution is the concept that there is some goal; that there is something good or bad in it.

    Whether we are here or not, whether any other species is here or not, is a "so what?" proposition.

    The universe got along fine for billions of years before the Sun or the Earth existed. The Earth got along fine for billions of years before there was any life on it. Life on Earth got along fine for millions of years without Homo Sapiens. It's getting along fine now. It will do fine when we are gone. The universe will get along fine after the Sun goes red and consumes the Earth. If the universe eventually disappears, we won't even be a blip in the scheme of things.

    In the meantime, let's try to make things as pleasant as possible. ...but...pleasant for whom? ....

    If we are the dominant species why should we care about fairness?

    In the sense of evolution, everything is irrelevant. Evolution does not care even if life goes on or not. Evolution is not a person, it's just a mechanical process without feeling.

    It is a mistake many people make. Even the name "evolution" is wrong because it implies a goal. There is no evolution, just meaningless change and a lot of suffering in consequence.

    It's worse than that. There is not even anyone around to ask "so what?".

    It's really all for nothing. The best we can do is seek pleasure while we can, and perhaps develop a way to die without enduring too much pain.

    For us! We are the ones for whom things matter. We are the lords of the universe and we can do with it as we please, since nothing matters except for us.

    I wouldn't be so fatalistic. Evolution may not care - it isn't a being with thoughts and feelings - but it certainly has a purpose or goal. Adaptation.

    That goal is entirely local. Different phenotypes interact and some of them leave more descendents with their genes than others do. This is "winning the hand" but not "winning the deal" let alone the game.

    If we are a result of evolution, then everything we do is perfectly acceptable since evolution has crafted us the way we are. We hold no responibility for any actions we make like raping, killing, or destroying.

    When we destroy our planet from pollution and wars then evolution have failed us. And will favor other species that survive.

    We also have created a social order to limit our evil side since that has allowed us to reproduce even more.

    That makes absolutely no sense, because we are alive, we should rape, kill, and destroy?

    Again you make no sense. If we destroy the environment that currently exists, evolution has not failed. Evolution will continue to rebuild the earth and some old species will adapt, some will fail, and some new ones will arise. Evolution is NOT meant to keep humans alive!

    Not at all!
    What it boils down to is that morality is necessarily a HUMAN construct; there aren't any transcendent laws unrooted in the condition of mankind that tells what is right.
    That, as it happens, is up to humans to figure out/negotiate about.
