GGG, as per your request:

Variations.

1. Variations exist with in all populations.

2. Some of that variation is heritable

3. Base pair sequences are encoded in a set of self-replicating molecules that form templates for making proteins.

4. Combinations of genes that did not previously exist may arise via “Crossing over” During meiosis, which alters the sequence of base pair on a chromosome.

5. Copying errors (mutations) can also arise; because the self-replication process is of imperfect (although high) fidelity; these mutations also increase the range of combinations of alleles in a gene pool.

6. These recombination’s and errors produce a tendency for successfully increasing genetic divergence radiating outward from the initial state of the population.

Selection

7. Some of the heritable variations have an influence on the number of offspring able to reproduce in turn, including traits that affect mating opportunities, or survival prospects for either individuals or close relatives.

8. Characteristics which tend to increase the number of an organisms offspring that are able to reproduce in turn; tend to become more common over generations and diffuse through a population; those that tend to decrease such prospects tend to become rarer.

9. Unrepresentative samplings which alters the relative frequency of the various alleles can occur in populations for reasons other than survival / reproduction advantages, a process known as” genetic drift”.

10. Migration of individuals from one population to another can lead to changes in the relative frequencies of alleles in the “recipient” population.

Speciation

11. Populations of a single species that live in different environments are exposed to different conditions that can “favor” different traits. These environmental differences can cause two populations to accumulate divergent suites of characteristics.

12. A new species develops (often initiated by temporary environmental factors such as a period of geographic isolation) when sub-population acquires characteristics, which promote or guarantee reproductive isolation from the alternative population, limiting the diffusion of variations thereafter.

Sufficiency

13. The combination of these effects tends to increase diversity of initially similar life forms over time.

14. Over the time frame from the late Hadean to the present, this becomes sufficient to explain both the diversity within and similarities between the forms of life observed on earth, including both living forms directly observed in the present, and extinct form indirectly observed from the fossil record.

That’s what Evolution IS! If you have a problem with Evolution you have a problem with one or more of these fourteen points. Which one is it? Provide any evidence of any of the points that are incorrect.

While the origins of life are a question of interest to evolutionary biologist and frequently studied in conjunction with researchers from other fields such as geochemistry and organic chemistry, the core of evolutionary theory itself does not rest on a foundation that requires any knowledge about the origins of life on earth. It is primarily concerned with the change and diversification of life after the origins of the earliest living things – although there is not yet a consensus as to how to distinguish “living” from “non-living”

Evolution does NOT indicate that all variations are explained this way; that there are no other mechanisms by which variations may arise, be passed, or become prevalent; or that there is no other way life diversifies. Any and all of these may be valid topics for conjecture…but without evidence, they aren’t science.

Other peoples opinions presented in the form of quotes are not evidence against the theory of evolution. They are merely opinions, and all people have opinions, which turn out to be false. So lets stick to the facts.

I said type out your graphic and then post it in YOUR OWN THREAD, and then ping me.
