Moreover how DNA genes are expressed is a function of the DNA code itself. One doesn't get a permanent change in expression pattern without a permanent change in the underlying DNA regulatory sequences that control the expression of the genes.
Variation within a species IS a measure of the difference in DNA among members of the species. If variation happens “rapidly” then obviously you are proposing that DNA change within the species happens “rapidly”.
How do you propose that variation in genetic expression can happen such that a ‘badger’ becomes different than a ‘wolverine’ without a change in the underlying DNA? Do you propose that both came from the same primordial “kind” WITHOUT a change in DNA? Just a matter of opinion that makes a Badger different than a Wolverine?
What is the difference that would cause a change in genetic expression, and how is this accomplished “rapidly” enough that all the “kinds” that could fit on the Ark could evolve into all known species upon the Earth?
We see beneficial mutations (which is NOT synonymous with evolution) all the time in experimental populations, in nature, and in our domesticated animals. The reason a Dachshund is different than a Wolf is because of variations in the DNA, and the artificial selection of ‘beneficial’ traits for short limbs, long ears, etc, that arose or existed in the population.
I like your reference to dogs. The dogs you site are a product of selective breeding and therefore support intelligence design. Keep posting and you may yet get totally confused by your own posts.
