“But you have to admit that both the 'routine argument' for evolution and Darwin's theories have their founding in a cosmology based upon the idea that 'first there was nothing, then something (along the lines of bacterial life), then everything evolved from there.'”
>>Evolution, however, makes no statements nor predictions regarding the transition from “'first there was nothing, then something”: it only addresses what happened once that something—populations of living organisms—were there.
How they got there—whether they arose as the result of magic, natural biogenetic mechanisms from non-living self-replicators, seeding onto the planet by extraterrestrials, etc.—isn’t within evolution’s scope.
“Creationism actually doesn't deny the laws of physics, it offers an explanation outside of natural law.”
>>Positing mechanisms which are outside of natural law is to deny that the laws of physics hold in our universe.
“The God of creationism is 'supernatural' and therefore natural laws that would clearly apply to evolutionary theory, a Creator would stand 'outside of.' It at the least offers a better possibility than the 'something from nothing' theories that much of the scientific realm brings forth.”
>>How does positing a god in the absence of any evidence to support one’s existence a better possibility than theories of cosmology that derive from a large body of evidence (red-shifting of galaxies indicating an expanding universe, cosmic background radiation, etc.)?
“But it does require a willingness to believe that man and nature aren't the 'center of the universe'.”
>>Evolution, big bang cosmology, abiogenetic models, etc., don’t predict that man or nature are uniquely privileged (i.e., the center of the universe.) Creationist theories, in fact support that perspective, given that they all indicate presume nature and man arose in a goal oriented manner—that we represent a preferred outcome.
“Most evolutionary theory that is taught both in our schools and at any Natural History Museum not only teaches that man evolved from a common ancestor, the ape, but demands that we all accept that as the only viable option.”
>>Well, at present evolution is the only real explanation on the table. “God did it”, after all, explains nothing (it simply avoids the necessity to derive an explanation by writing everything off to magic) and is indistinguishable from “Pixies did it”, “Leprechauns did it”, etc., on any basis other than personal taste.
“Macroevolution is evolution on a grand scale, such as the development of a new species. Your example of a new 'species' of mouse would only apply if that new 'species' was unable to interbreed with any other breed of mouse.”
>>Which is what has been directly observed: new species which are reproductively isolated from all other species arising by descent with modification. With respect to mice, there’s the interesting example of multiple speciations in populations of mus musculus domesticus, occurring as the result of Robertsonian fusions altering karyotype numbes reported in "Chromosomes and speciation in Mus musculus domesticus", E. Capanna, R. Castigli, Cytogenetic and Genome Research 2004;105:375-384 . Five different new species arose by descent from a common ancestral population, all reproductively isolated from one another.
“Most often what you're referring to is actually a new breed, not a new species.”
>>Maybe when others refer to new species arising by descent they’re mistakenly referring to breeds. I’ve been employed as a research biologist/molecular biologist/immunologist for more than 25 years, and am very careful to use the correct terms and get the facts right.
“Typically a species is an entirely different variety of life, with possible similarities to another species, but genetically unable to interbreed with other species, such as humans and apes.”
>>Humans, gorillas and chimpanzees phylogenies actually diverge at a taxonomic level higher than that of species—humans are genus Homo, Gorillas genus Gorilla, and chimpanzee’s genus Pan. And there exist different species of mice which cannot interbreed, multiple different species of fish, which cannot interbreed, etc.
