Do you agree with this statement about natural selection and life?

Natural Selection and Adaptation Preserve Life Forms, Rather Than Generate New Ones

Plants and animals were originally created with large gene pools within created kinds. A large gene pool gives a created kind the genetic potential (the potential to produce a variety of types within a kind) to adapt to a variety of ecosystems and ensure the survival of that kind of organism through natural selection.

Genetic potential can best be understood by observing the large number of dog breeds. There are many shapes, sizes, and colors of dogs, illustrating the tremendous genetic potential in this kind of animal. Other kinds of plants and animals have similar potential to produce variety within a created kind.

Natural selection can only operate on the genetic material already present in a population of organisms. It cannot create new genetic information and subsequently change one kind of
life into another.

It is an interesting argument, but no I don't agree.

Anomalies in life occur. DNA can be manipulated through natural selection. Mutations can and do occur, and in some cases will cause offspring to be better adapted than their parents.

"Natural selection can only operate on the genetic material already present in a population of organisms. It cannot create new genetic information and subsequently change one kind of

life into another."





How do you know? Animals (including humans) are born all the time with extra fingers, extra toes, etc. How can you be so sure that the same thing can't happen on the genetic level to DNA?

That's true, but irrelevant. New genetic information and phenotypes arise from genetic mutation, chromosomal crossover events, and errors in DNA replication. Natural selection (and genetic drift) then determine which phenotypes to propagate to the next generation and the process repeats.

True, Natural Selection is only one part of evolution however, mutation generates new genetic information, and natural selection "selects" the favorable ones. For example, bright fur in the desert as opposed to dark fur.

i won't manage to communicate for theists because of the undeniable fact that i don't individually have confidence in a deity, yet i think of human beings in often prefer to sense that something or somebody is on top of problems with issues that they have no administration over. perchance not inevitably a loving, etc. god, yet one that does have some accountability of understanding what somebody would not know. human beings are uncomfortable with the undeniable fact that each and everything happens accidentally and/or is a fluke or perhaps though you will prefer to call life. there is not any choose for a deity. we choose for our own way with the aid of life with the little administration that we've over the failings around us. different issues can conquer that administration and *blam*... somebody gets hit via a bus. returned to the 1st few lines of the question... The 'clockwork' god is mind-blowing, yet holds no water. 'What grew to become into the 1st mover?' question is invalid. technology has not gotten to the initiating yet, even though it has gotten to interior theoretical milliseconds of the initiating of the universe (enormous bang). What grew to become into there until now's a touch foggie thought and particularly recommendations boggling, yet some theories exist for that too. recommendations are mind-blowing, yet without scientific information or information, they don't seem to be properly worth plenty better than lip service.

Well, with experiments like the Miller-Urey experiment, I would say that your last two sentences could be debated (see references below).



Of course, there are limitations to these experiments, but taking into account physics and chemistry, it makes sense that organic molecules could have begun from inorganic ones.

I think you need to read more about natural selection.
