You will find that those who believe in evolutionary thought absolutely believe in microevolution. Interestingly, those who subscribe to intelligent design also believe in microevolution.

How is microevolution different?

Microevolution is a built in adaptability that all creatures have to adjust to certain changes. An example would be a species of insects that become resistant to pesticides or birds that adapt to a new climate.

According to a Berkley website, "Biologists who study evolution at this level define evolution as a change in gene frequency within a population." [1]

If this were the universal definition of evolution perhaps there would be a consensus on the subject. However, those who subscribe to intelligent design see microevolution as consistent with a 'good' design of species, but separate from common evolutionary thought. If, within a species, creatures can be observed adapting to their environment this may be evidence that the design of the species was more than adequate for the needs of the species.

Intelligent design proponents can agree with microevolution because it is observable within species.

So why don't intelligent design proponents accept evolution?

Intelligent design advocates believe that evolutionists make a significant jump when they assume that microevolution (which is observable) is the smoking gun for macroevolution (which is not observable).

Microevolution is observable and is consistent with both intelligent design as well as evolutionary thought.

The difference is intelligent design supporters contend that the species that may be adapting to its environment still remains the same species. They contend it is a leap of faith to assume that 'species adjustment' is in the same category as the development of a new species.

Evolutionists contend that what is observable in microevolution helps explain the origin of species through natural selection. In essence, the thought process is, "If it can happen on a small scale certainly the same principle applies to species evolution."

The difficulty

The problem with making this assumption is that no one has yet observed one species developing into something new. Certainly we can see a variety of different dog breeds, but they are still dogs. We see genetically altered rats with mice DNA, but they are still rodents. We see a variety of horse breeds, yet they are still equines.

Final thoughts

Microevolution is a wonderful means of seeing how adaptable all species are in the face of an environment that may threaten their existence. This process is observable and may be classified as a true miracle of science.

Or…

Perhaps species adaptation
looks designed because it is designed.
