Misconceptions/Hardy Weinberg...
Greenburke,
Maybe it would help if you knew what the forces of speciation are..
1.) Non random mating (Consanguineous mating, Assortative mating)
2.) mutations
3.) migration
4.) natural selection (Fitness of offspring to reproduce)
5.) genetic drift (Alleles that no longer exist)
These are the forces that drive speciation, not just mutations.
I don't agree with most of the stuff you posted but I can't rebut now because i just saw something worse...
"ok someone who is an evolutionist please answer these questions... If we are animals then why are we being punished for acting like animals? Why are the public schools having problems with gun fights and the such when they have been taught evolution all their lives, meaning they are just shooting another animal? Please i am at a loss as too how to understand that you can say that we are animals, but when some acts like one they get in trouble."
:rage: WE ENTERED INTO SOCIETY, WE HAVE A SOCIAL CONTRACT TO FULFILL. WE HAVE FREAKIN LAWS!!!! :rage:
It's that simple. Common man, this isn't a real question...is it? Don't make me bring out Rousseau, John Locke, Neitzsche etc...
Kudos to emily for answering his question with a level headed approach. Very eloquent. I would say though that there is probably a heirarchy to the animal kingdom, as there is in human affairs. I don't know about the morality of it all though either but we are digressing fast. Morality to me is such an ugly term.

Everyone has seen paintings in museums and textbooks of our "family tree," with its worms, birds, apes, and man shown in relation to how they evolved from one another. The impression is given that there can be no doubt that it really happened that way, for did not scientists prepare those charts?
"Delicate twigs, burgeoning in all directions, is closer to our current idea of evolutionary history."—*R. Milner, Encyclopedia of Evolution
All it really consists of is separate twigs, with each twig a separate species.
Classification is only the box species are put in, not the proof of evolution.
Chickadees. The Carolina Chickadee (Parus carolinus) and the black-capped Chickadee (Parus atricapillus) look just like each other in every way, and freely interbreed. Yet they have different songs! Although they have been classified as two different species, we have here one species with two alternate gene factors.
Wheat. Linnaeus classified spring wheat (Triticum aestivum L) as a different species than winter wheat (T. hybernum L). Yet they are both strains of the same wheat. They will cross and produce fertile hybrids. They should have been classified as sub-species.
Song sparrows. For over two centuries four species of sparrows in North America had been listed (Lincoln, fox, swamp, and song). Gradually this number increased as taxonomists moved westward and found additional sparrows. Soon we had lots of sparrow "species." But as more and more were discovered, it was recognized that they were but intermediates between the others! So the experts finally got together and reclassified them all as sub-species of but one species, the song sparrow (Passereila melodía).
Cattle. There are several different subspecies of cattle (Bos taurus L). Although the American bison (Bison bison L) and the European bison (Bison bonasus L) have a similar morphology (appearance), they will still generally crossbreed with cattle. In addition, it has been discovered that the African buffalo (Syncerus caffer) also interbreeds with them—yet the bison and cattle have been placed in totally different genera.
Corn. One expert (*Sturtevant) categorized 6 species of corn (sweet, flint, flour, pod, dent, and popcorn), while other taxonomists acknowledge that they are all only varieties of one species.
Evolutionists point to changes WITHIN the species and call that "microevolution," and then proceed to tell us that such sub-species changes prove that theorized changes ACROSS species (which they term "macroevolution") must also be occurring.
But random gene shuffling within the species only produces new varieties and breeds. The DNA code barrier is not penetrated. New plant varieties and animal breeds never cross the species barrier.
There are many different sub-species in some species while there are but few for others. A key factor seems to be the ability of the creature to travel (migrate) migrate whether by seed, spore, or in person.
For example, the tiny fruit flies cannot travel very far, so there are many varieties of them. The animal with the most sub-species appears to be the southern pocket gopher (Thomomys umbrinus) with 214 subspecies and, next to it, the northern pocket gopher (T. talpoides) with 66. Another highly isolated species is the deer mouse (Peromyscus maniculatus) with 66 subspecies.
"There is no evidence of the origin of a hybrid between man and any other mammal."—*Edward Colin, Elements of Genetics
Yes, variations are limited by the species barrier,—but immense variations are possible within a given species!
New varieties and new breeds are not evolution; they are only variation within the already existing species. There is no such thing as "microevolution." Changes within the true species are not evolution.
