A question for the "evolution is stupid" advocates in this thread:
If as you claim evolution of distinct new "kinds" (or "macroevolution") has never occurred, what exactly has been stopping it?
Given the following facts:
1. Gene distributions in populations of organisms change with time.
2. Populations of the same species can become isolated from one another.
3. Gene distributions in populations that are isolated from one another change in different ways.
4. Genetic differences change the physical and behavioral characteristics of the organisms in a population.
5. Physical, behavioral, and genetic characteristics of organisms determine whether or not they can breed with one another.
... what force could possibly prevent all occurrences of a population becoming split into two or more isolated groups, the two groups micro-evolving in different ways, and eventually becoming unable to reproduce with one another between the groups?
Does God notice that the antelopes in the grasslands west of the lake are micro-evolving shorter legs because it gives them better concealment, while the ones in the patchy forest east of the lake are micro-evolving longer legs because it gives them better access to edible tree leaves, and say to Himself "Uh oh, if this goes on they won't be able to mate with one another any more, which would mean a difference in Kind which be an abomination in Mine eye," and smite one of the herds to prevent it? If not, what force does accomplish this feat of preventing microevolution from making two kinds out of one when populations become physically separated?
Observing that forests are filled with stuff that can burn, and that lightning can ignite stuff that can burn, and that lightning sometimes occurs in forests, it is reasonable to conclude that forest fires sometimes occur, even if no record existed of any having occurred. Unless one could propose a reasonable hypothesis for what stops them from occurring.
Observing that populations reproduce with genetic variation and recombination, and that they live in an environment where rivers sometimes change course, peninsulas sometimes become islands, lake levels sometimes change turning one lake into many, fertile areas sometimes turn into deserts, and so forth, it is equally reasonable to conclude that speciation occurs even if no record existed of it having occurred. When such records (including fossil and genetic) do exist, in abundance, denying it becomes utterly unreasonable. Unless one could propose a reasonable hypothesis for what stops it from occurring.
So, what prevents "macroevolution" from occurring? The floor is yours.
Respectfully,
Myriad
