Hi JRTjr, welcome to the fray, if I haven't already said it.
I hope you are reading the replies and intend to return & respond at some point. Unfortunately it seems the major thrust of your OP has been obscured by the posts so far
I propose to dedicate a string to whether or not I can, using scientific methods, definitions, and evidences, disprove ‘Macro-Evolution’ {Also known as ‘Darwinian Evolution’ or ‘Natural selection’}.
It appears that you have some misconception about macroevolution. ‘Darwinian Evolution’ is a term commonly used by creationists to talk about microevolution, and natural selection is a part of ‘Darwinian Evolution’ and microevolution.
... when I say Macro-Evolution I am speaking only of a scale of analysis of evolution in separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population. {Quoted from Wikipedia.org}
Another source for definitions about micro and macroevolution is:
The Process of Speciation
quote:
Definitions of Biological Evolution
We begin with two working definitions of biological evolution, which capture these two facets of genetics and differences among life forms. Then we will ask what is a species, and how does a species arise?
- Definition 1:
Changes in the genetic composition of a population with the passage of each generation
- Definition 2:
The gradual change of living things from one form into another over the course of time, the origin of species and lineages by descent of living forms from ancestral forms, and the generation of diversity
Note that the first definition emphasizes genetic change. It commonly is referred to as microevolution. The second definition emphasizes the appearance of new, physically distinct life forms that can be grouped with similar appearing life forms in a taxonomic hierarchy. It commonly is referred to as macroevolution.
A full explanation of evolution requires that we link these two levels. Can small, gradual change produce distinct species? How does it occur, and how do we decide when species are species? Hopefully you will see the connections by the end of these three lectures.
In science macroevolution is considered to have occurred when speciation occurs, where a parent population divides into two or more daughter populations that no longer interbreed.
Can you describe what you think occurs in macroevolution? Do you think something other than microevolution occurring in different populations of breeding organisms living in different ecologies results in different adaptations within the different populations? How much change is necessary for macroevolution to be demonstrated?

Enjoy.
