Variation within the Dog Kind
Oftentimes evolutionists will misrepresent the creationist position by claiming that the Bible teaches God programmed animals to reproduce after their kinds with no variety whatever. This claim is false. According to Acts 17, God programmed our first human parents with enough genetic information to account for the variety in human beings we see today. God is interested in individuals, not duplicates!
Within the dog kind we see the same kind of unfolding of genetic potential. The first generation of dogs had medium length fur, but contained the information to produce a variety of puppies. Nature will select the most fit for survival, who will then pass their information on to the next generation. Notice that there is only a shuffling around and an editing of existing genetic information. Evolution requires brand new information be created, which is something that we've never observed.
