The Limits of Natural Selection: How much can a species change? Part 11

The Naturalistic Evolutionary Model:


An Intelligent Design-Young Earth/Cataclysm Model:

“Speciation is unobservable,” said one evolutionary biology teacher restating the current evolutionary thinking on the subject. Evolutionary theory states that mutational changes are too slow to demonstrate the required amount of change for new species to develop in experimental time frames.

Natural selection is universally recognized. No known natural selection processes, however, have been demonstrated to cross major barriers. So called “micro-evolution” is most likely natural selection at work within the boundaries of inherent variability (as described by neo-Mendelian genetics and the DNA code). Naturally selected variability can lead to species differentiation such that there are many kinds of finches, many kinds of dogs, many kinds of cats, varied forms of the HIV/AIDS virus, etc. These variations (incorrectly called mutations) are inherent to the gene code, but these are not capable of producing new organs or macro-systems such as: flight; eyes; speech or radar capability.

The fact that organisms have an inherent ability to adapt through natural selection is an argument in favor of design. Adaptability requires a higher level of design than non-adaptability. For example, a software program designed to function exclusively on one platform, say Windows OS, requires less information than one, which is designed to function on Windows, UNIX, LINUX and Mac environments.
