Speciation is the process of developing subspecies - not new species. A very simple example would be long haired dogs in cold climates and short haired dogs in hot climates...both descended from the same ancestors. The ancestors had dominant and recessive genes for both long and short hair. But over time, long haired dogs don’t survive in hot climates; short haired dogs don’t survive in cold climates. That is natural selection: no new bio information is developed; information for one or the other is lost. That is a very important part of the intelligent design theories.
Excellent summary, LK!
That analysis is reasonable, but as usual, it suffers from a lack of comprehension of the power of "compound interest", or the nature of time on variation.
As previously posted in a different thread, one of the first abilities that evolved was the ability to evolve rapidly to adjust to changing circumstances.
We have difficulty perceiving this concept because we have seen too little evolutionary pressure in the time we've been looking for it.
An ability to grasp the concept of "geologic time" is essential to see how lifeforms morph and wriggle to escape the grasp of predation or the ferocious maw of hunger.
