A Great Book
This is a great book for two reasons: It provides a clearly presented explanation of how our DNA relates to our evolutionary development, and it presents an enormous amount of evidence that can be used against creationists and proponents of intelligent design. It has been frequently said that humans and chimpanzees have very similar DNA. This book shows just how similar they are, and it presents a spectacular example that pretty well proves that humans and chimps had a common ancestor--an example that the creationists cannot rationally refute. Humans have 23 chromosomes, whereas chimpanzees have 24. That difference in number is the result of two of the chromosomes that were in the common ancestor having combined at one of the ends of each into one chromosome in the human line, thus reducing the total number in the human line. The evidence for this is to be found not only in the similarity in the DNA of the combined human chromosome when it is compared with the two chimpanzee chromosomes, but also in the remnants of the currently nonfunctioning telomeres and one of the centromeres that were originally in the two ancestral chromosomes. Those telomeres, which normally would be found at the ends of the chromosomes, and the centromere are in the exact locations within the the human chromosome if the chromosome had its origin in the two chromosomes of the common ancestor. On top of that, the functioning centromere in the chromosome is in the exact location of the other centromere in the chimp chromosome.

This is a very readable book on how genetic evidence supports evolution. Anyone interested in evolution should read
this book. The explanations are very clear and helpful. Really worth having in your library.
