What is actually true about evolution?

Question

Those of you who feel evolution explains the origin of DNA on the planet. Tell me one thing that you KNOW is true about evolution. A fact that will not change, that has not changed. Just curious. (can i check with you in 20 years to see if you are right?)

Answer 1

There is nothing about the formation of DNA it is about the relative levels of genetic expression in the population. If a trait gives one individual an advantage in fitness so that more offspring survive to reproduce the trait will spread through the population. Add to this that some traits are selected sexually.
Selection acts on slight variations in traits.
Little things like more or less pigment in hair, eyes, and skin can allow the individual to be resistant to UV damage or very vulnerable to it. In the tropics it is very important to be have more pigment to avoid the UV damage. In the high latitudes the UV is less intense so when a chance mutant with less pigment appeared it survived. Chance mutation in the right place.
Documentation of changes was laid down for us by the preservation of fossils. Especially now that DNA preserved in amber or other fossils can let us sequence 20 million year old material for direct evidence of phylogeny.
The most exciting find in the evolution of humans has been the sequencing of Neanderthal mitochondrial DNA. We have a better idea of how divergent we are from them since the current sequence seems to support the notion they are a separate species.

Answer 2

>"Those of you who feel evolution explains the origin of DNA on the planet. "

I know of *NOBODY* who feels that evolution explains the origin of DNA on the planet.

The theory of evolution is about the development of modern species from earlier ancestors. Period. It does not claim to explain the origins of life, or the origins of DNA.

>"Tell me one thing that you KNOW is true about evolution. A fact that will not change, that has not changed."

This is why creationists just don't "get" science AT ALL. The entire point of science is that it is *never* static. It is *always* changing, always improving. New facts are discovered all the time. Old facts are shown to be inaccurate, and replaced with more accurate measurements.

For example, currently we believe that only about 2% of DNA actually codes for proteins ... the rest being basically "junk DNA." It is possible that maybe the correct number is more like 3%, or maybe even 5%. So that fact is subject to revision. But it doesn't change anything as far as evolution is concerned. Because *any* junk DNA is evidence of evolution ... as it is evidence of billions of years of copying copies, and of long unused DNA from distant ancestors.

Answer 3

If you had any education in biology, you would know that evolution is "true" just from its definition. Evolution is defined as the change in allele frequency in a population over time. If you don't know what alleles are or what a frequency or a population are, then of course you don't understand what evolution is. In simpler terms, it is change in DNA over time.

Evolution has nothing to do about the origin of DNA (that field is called abiogenesis), only what happens to the frequency of bits of DNA between generations. We know this to be true because we can measure it. 20 years or 20 centuries from now, evolution will still be the change in allele frequency in a population over time. It happens. It is happening. Anyone can go out and measure it with the proper tools.

Get a clue before you attack something about which you are so ill informed.

As T. Wallace has said, “A major reason why evolutionist arguments can sound so persuasive is because they often combine assertive dogma with intimidating, dismissive ridicule towards anyone who dares to disagree with them. Evolutionists wrongly believe that their views are validated by persuasive presentations invoking scientific terminology and allusions to a presumed monopoly of scientific knowledge and understanding on their part. But they haven’t come close to demonstrating evolutionism to be more than an ever-changing theory with a highly questionable and unscientific basis. (The situation isn’t helped by poor science education generally. Even advanced college biology students often understand little more than the dogma of evolutionary theory, and few have the time [or the guts] to question its scientific validity.)”

And as Dr. Michael Houts said, “This illustrates another key (non-scientific) feature of the theory of evolution. The theory is constructed in such a way that no matter what the evidence, evolutionists can claim it supports their religion. If a bird is brightly colored, it evolved vivid feathers to attract a mate. If a bird’s plumage is drab, it evolved that drabness to provide camouflage. If similar structures are derived from similar gene sequences, it is because the two species share a common ancestor. If similar structures occur in species that are genetically quite different, it is because of 'convergent evolution.' No matter what the evidence, in the eye of the believer, evolution is true.

One criterion for determining if a theory is scientific is if it is falsifiable. In other words, the theory must be constructed in a way that an experiment could be devised to prove it false. In the discussion of similarities between organisms, the theory of evolution is purposely constructed so that no experiment can prove it false."

As Dr. Jonathan Sarfati says, we need to quit calling evolution a theory; that is giving it too much credit. “Goo to you” evolution is an unsubstantiated hypothesis or conjecture, not a theory.

Swedish biologist Soren Lovtrup made an interesting statement: “I suppose that nobody will deny that it is a great misfortune if an entire branch of science becomes addicted to a false theory. But this is what has happened in biology...I believe that one day the Darwinian myth will be ranked the greatest deceit in the history of science. When this happens, many people will pose the question: How did this ever happen?”

Answer 5

that's a miles stretch to take the real data for evolution and enhance that concept and knowledge to the component of affirming as a real end that each and all of us life began from a single user-friendly organism and by the years, by random procedures and genetic mutation, branched into all dwelling organisms that have ever existed and exist immediately. I very lots help effortless scientific discovery of the procedures that govern life, yet i do no longer purchase into the fairy memories they have spawned. have you ever considered what number different loopy theories there are on how that first organism got here to be? maximum "actual" evolutionists only say that's not as much as evolution to make sure the reason for that first life, only to coach how, as quickly because it have been given all started, the technique of evolution has worked. do no longer you spot that as an incredible cop out and a gaping hollow interior the concept in case you decide directly to apply it to eliminate God's imaginitive hand? and how did all the advice get encoded into our DNA? Any good theories on that? And why might single celled organisms that divide completely to create mirror photos of themselves substitute into multi-celled and "evolve" to a miles less suited sort of sexual replica by the years? And why might a creature born with gills and a respiration equipment designed for underwater respiratory have an offspring with lungs and a respiration equipment designed to breath air? And if a genetic mutation motives speciation as infrequently as is postulated, with what did that new species mate, would not a male & lady with that comparable genetic mutation that brought about that speciation ought to be interior an identical place on an identical time to effectively mate and create extra attainable offspring? What precisely is the real data that solutions a majority of those questions lower back? Please attempt to maintain your data and fantasies separate.

Answer 6

Evolution is not the origin of DNA.

Evolution is the evolving of a spieces to adapt to their climatic surroundings to ensure their survival.

IT IS NOT the beginning of life as we know of it today, yesterday or tomorrow.

Answer 7

I disagree with the idea of evolution. I am a christian. But I believe in Micro evolution (look it up) not Macro Evolution (the so called Orgin of species BS)

Answer 8

Natural selection.

Answer 9

The critters that have more offfspring are better represented in the next generation. It's not too complicated. :)
