    Is bacteria the most evolved and adaptive life form on earth?

      Any form of life that persists is adapted to its niche--there may be more or less adaptive fitness, but I don't think there can be "most".

        Considering all forms of life on this planet, which do you think has the greatest chance of surviving the worst catastrophes the earth can experience, oh say, for the next 1 1/2 billion yrs when the earth will most probably become to hot for most life to exist?

            Popo:
            I hadn't considered "archaea."
            You are quite right. I had always classified them as bacteria.
            Ty for bringing me up to date...appreciated..
            Ok lets add them to this forum question.." bacteria and archaea."   :-)

              Anytime quark. I assumed you classified them as bacteria, I do the same. But they are incredibly unique, wouldn't you agree?

          smile  I'm just being difficult, I guess.  I don't honestly feel bacteria is a life form because if it were then Earth would be a life form.  I accept bacteria and Earth are alive, just as trees and other plants are, but I cant agree to a living breathing life form without the necessities.  Bacteria doesn't think, it just survives because that's what it was meant to do.  smile  jmho.

                Clearly intelligence or the ability to think,does not require consciousness, nor does it require feelings or emotions.

                One might also ask what consciousness has to do with intelligence. Since we know that computers have intelligence and no consciousness, why should we even classify intelligence with consciousness at all?

                Consciousness has more to do with feelings and emotions (qualia) than it does with intelligence. In fact you can even train yourself to eliminate thought (and thus intelligence) through mediation or biofeedback techniques, at least briefly, but you will still feel.

                It appears that consciousness evolved later in complex brains, perhaps even as an emerged property of brain chemistry.

                You might ask yourself at what level of evolution does consciousness exist in animals. We have little problem with seeing evidence of consciousness in humans, apes, dolphins, or even cats and dogs, but what about insects, microbes and viruses?

                Trying to pigeonhole just where non-con consciousness ends and consciousness begins only misses the mark and can lead us to create reification fallacies.

                  computers dont have intelligence - intelligence is the ability to think.

                  Computers have stored intelligence - which involves the ability to recall information.

                    This has been a much debated question in that you weren't born with intelligence but it was learned.

                    First of all I have would like you to answer a question.

                    What is 4x13? Did you have to think to answer that? Yes? Well does that mean that a computer can think because it can answer that question.

                    I think yes, depending on your definition of thinking.

                    From everything we know about intelligence, one thing remains clear: intelligence requires some kind of central processing system-- a brain. Whether the brain consists of biological or electrical components, it must have the capacity to acquire and apply knowledge by means of thought and reason.

                It's a bit big to be doing them without anyone noticing.  But if it is, then it is alive. (I don't think it is).

                  Living organisms undergo metabolism, maintain homeostasis, possess a capacity to grow, respond to stimuli, reproduce and, through natural selection, adapt to their environment in successive generations.

                  By that definition, planets are not "living". But Earth does contain living creatures, which you can consider as cells of the planet. It can also be healthy (thriving with life) or unhealthy (a barren wasteland).

                    Indeed, that is the more complete way of saying it.  "Life" is defined biologically.

                    Well, Mrpopo, let's see here.  The earth constantly "eats" meteors and as a result is still growing.  Tectonic plates are continually being forced down into the interior, while volcanoes produce lava coming out; this maintains the homeostasis process.  We "stimulated" it in the gulf of mexico and it is still spitting at us like an octopus.  When tapped by another planet a few years ago it produced the moon, which is also growing.  Not sure if it can evolve; we've only seen it only in the environment of space.

                  Science has already discovered that the Earth is still evolving. Therefore it is alive. It reproduces life forms, grows different arrays of life-forms. It no longer produces human life forms because it's evolved beyond that by now.

                    Can you show me where science has discovered this?

                    A dead carcass is home to bacteria and scavengers, which grow and reproduce.

                    I don't think you can consider that to be "living" simply because it has living things in it.

    The most successful life is that which can exist under the most conditions. That's what makes us successful - and bacteria even more so. And of course, bacteria will outlive us. They were here first, and they'll still be here - long after we are gone.

    It's their own basic simplicity and meager needs that insure their success.

  3. mrpopo profile image74
    mrpopoposted 8 years ago

    I think they're the least evolved. Isn't that why they're the most adaptive?

    1. qwark profile image56
      qwarkposted 8 years agoin reply to this

      They are highly evolved and adaptive.
      They are "simple" and can mutate to adapt to a change in environment very quickly. Every time they must adapt, their genetics adjust to allow the bactera or archaea to survive.
      Their evolution has been empirically proved.

        Actually, I don't even know what is meant by "more evolved" or "less evolved" to be honest.

        Can anyone clarify that for me tongue

        1. psycheskinner profile image82
          psycheskinnerposted 8 years agoin reply to this

          I don't think is really means anything.  Anything adapted to its niche is "evolved".

          1. mrpopo profile image74
            mrpopoposted 8 years agoin reply to this

            That's true. But what if its niche is the entire planet? Would that make bacteria more evolved?

            I guess that's true for us too, as humans.

              psycheskinnerposted 8 years agoin reply to this

              I think any given species of bacteria has a niche, which is not the whole planet.  Counting them as a group would equate to counting all insects and animals as a group and possibly lumping them in with plants too....

            qwarkposted 8 years agoin reply to this

            A life forms ability to adapt to its environment is the processes of "natural selection" in full function.
            As environment changes, the unadaptive die off.
            The successful are those which can adapt rapidly to environmental changes.
            Those changes are the result of an organisms biochemistry adjusting to new environments.
            The more able an organism is to make those adjustments the greater is its ability to "survive."
            The simple fact that bacteria and archaea will outsurvive us is indicative of it being more "highly" evolved, in it's "simple" form, than man.
            Understand this tho, bacteria and archaea are very complex little organisms.
            The "goal" of all life is: "survival!"

              psycheskinnerposted 8 years agoin reply to this

              I would argue that the goal of life from an evolutionary point of view is reproduction.  Oops,I failed "life" smile

                qwarkposted 8 years agoin reply to this

                Biologically speaking, the basic tenet of the study is that the "goal" of ALL life is survival.
                Procreation is but a facet of that goal.
                "Life" cannot exist without "survival."

                  Survival cannot be accomplished without life.  Sounds like a never-ending cycle to me.
