The code that is DNA

Yeah, Saying "I believe in micro evolution but not in macro evolution" is like saying "I believe in minutes but not in hours, and definitely not in years and decades".

There's a reason why biologist make a distinction between microevolution, speciation, and macroevolution. Consider for instance that if gradual changes simply accumulate within a single population across x number of generation, speciation never takes place.

1 year is 31,556,926 seconds.

Given enough various isolated groups of the same animal, in different habitats, speciation will occur, via the forge of natural selection of genetic mutations throughout a species generations. This has been demonstrated in the lab with bacteria and happens from generation to generation, where one bacteria, through natural selection of genetic mutation, is able to survive in a different habitat that its predecessors did not.

You can flail around all you want about "distinctions", but the science is in; evolution occurs in all populations' differing habitats, where natural selection weeds out the genetic mutations that are harmful for the species survival in its own habitat, leaving the survivors able to breed for its next generation.
