a question for an evolutionist?

Question

if you are an evolutionist, please answer this question: how is evolution possible if everything developed gradually? let me clarify: aren't the reproductive, digestive, respiratory, and other organ systems VITAL to the continuing of life? if the "early organisms" had no reproduction capabilities, how did we come to be here? If the "early organisms" had no digestive systems, how did they have energy and fuel to "evolve" in the first place? no rude answers please, i want to know how you ardent evolutionists get around this question, and i promise i mean no rudeness myself. --:-)mutual goodwill(-:--

Answer 1

First, no such thing as an evolutionist. It's not a religion.

Secondly, I don't mean to be rude but there are simple forms of life (bacteria is a good example) all over the place right now that have no complex reproductive, digestive or respiratory systems. Are you completely ignorant to that fact?

Answer 2

This whole difficulty with the idea of evolution comes from the misconception of irreducible complexity. That is, the idea that certain systems in animals as we know them today simply cannot function as anything simpler. The classic example is the eye, which requires all its components to work. So how did that evolve?

The mistake is the restriction to the notion that it has to always work, or have worked, exactly as it does now. Yes, our eyes would not work so well if you took out the lens, for example. But the light sensitive cells of the retina would still respond to light falling on them, even if the eye could not focus that light as we can to bring objects of different distances into sharp resolution. True, if we lost parts of our digestive tract we'd have problems, but there are simpler organisms around that do not have such complex digestive systems and they have no trouble surviving and reproducing. Our reproductive systems may be horribly complex, but there are many organisms with much simpler ones.

This is the key: a system does not have to work as well as or in the same way as ours, it just has to work well enough to alllow the organism to thrive.

I certainly don't claim to know the subject in depth, but from what I have seen and read, the current life on this planet, and the fossils of life that is no longer present, are replete with evidence of the adaptation of simple functions and organisms to more complex ones. Evolution was not just something plucked from the air. It really is supported by a vast amount of evidence. creation (without wishing to offend any creationists) seems to me to be a cop-out answer, as 'the creator made it that way' can be used to answer any and all questions without actually trying to find out more about the subject.

Answer 3

The early organisms HAD reproductive capabilities and a digestive system. How do you think we're here today? I don't think anyone ever said the first form of life that we came from had no way of reproducing or a way of getting energy. Even single-celled bacteria reproduce a-sexually by mitosis... And plants can get energy without physically eating anything, all it needs is water and sun light....

Answer 4

Examples already exist today of very primative organisms all the way up to complex organisms. You can start with bacteria & trace life up through protozoa, algae, jellyfish, worms etc. It's as if you have the entire evolutionary process still available to inspect, although not the complete record.

Look at bacteria. They divide to reproduce, they just absorb nutrients. Some have primitive means of moving. Then you reach eukaryotes and some of them have eyespots. Then there are multicellular organisms but no speciallized tissue like seaweed. Finally, look at jellyfish. Very primaitve, just a bag of cells with a central cavity for absorbing nutrition. They also have a primative neural net & sting cells.

Most scientists believe that life can evolve continuously through stages LIKE these ( not necessarily these) & part of the proof is in the organisms that exist now.

Answer 5

first of all there is no such thing as an evolutionist. Evolution is not a cult nor a religon. It is science. So to be correct you should say.....hello scientists...could you please explain evolution to me in this sense..blah blah blah

Now to answer ur question. The organs u speak of r complex organs evolved over billions of years. And early organisms such as bacteria did have reproductive capabilities and digestive systems. There are a lot of details on how one bacteria can carry out these functions. You should research on any text book that is has 'Cell Biology' in its title. Now through competition for survival....organisms have developed ways to get the upper hand. At one point in life history...cells began to work together...and became a multicelluar organism over time. Now time after time...a race to become bigger was equated with success so to grow bigger...multicelluar organisms had to have some cells to specialize so that it could grow bigger. If u do the math between volume and area.... u can see that as u increase in volume....area lags behing a lot so the rate of diffusion for oxygen is not fast enough for the survival of the cells that are on the inside ( oxygen is needed for the krebs cycle. If u dont know what that is...look it up). Over time...things got more complicated as u can see with the organism VOLVOX (ck this protista out. It'll blow ur mind). And photosynthetic organisms was the first to become the big giant organisms....and like before....competition is always present so other organisms started to evolve ways to consume these photosynthetic organisms. IS BACK AND FORTH with lots of detail...eventually u have small animals like the sea anoemes that uses the mouth as the butthole too..things got more complex as time went on. Im barely scratching the surface and you have to really take classes on zoology...biology...palentology to get a solid understanding of evolution. Because evolution is not a guess...is not a maybe.... is a theory backed by millions of pieces of evidence from many disciplined fields of science rigoriously tested for decades. To refute this theory is like you saying gravity doesnt exist because it's a theory. Bottomline....everything in science is theoritical....everything created that u see today is based on scientific theory. You should also look up the word theory in a scientific sense.

Good luck !

Answer 6

I would not describe myself an "ardent evolutionist" but I do consider it a possibility that God's plan was to create physical laws that inevitably bring forth life under the conditions of primitive earth. "God first formed Adam out of the dust of the ground". This is not exactly a creationist point of view but is definitely not atheistic.

Also, most of the evidence today suggests that mutations came in batches after long periods of little change. Not smoothly over a long gradual stretches of time. Simultaneous multiple mutations presents possibilities that development over time is not strictly a linear progression of one trait after another.
