Neil Shubin Chapter Summary

We are all sharks underneath the skin, to put it more precisely we are all modified sharks, said fossil expert Neil Shubin. As Shubin makes it clear, evolution does not proceed in mighty anatomical jumps but to the process of gradual changes, transforming a gene, cell, or bone for a new purpose. In this way new species are eventually created. Albeit, a new species that still carries traces of it's evolutionary predecessors, an inner connection between fish and humans. You can see these biological stigmata today, says Shubin. Our hands resemble fossil fins, our heads are organized like those of long extinct jawless fish, and major parts of our genomes still function like those of worms and bacteria. Hypothetically we are all "shark siblings". …show more content…
For instance, fossilized fish fins that look a lot like those of the human hands, teeth first discovered in ancient jawless fish, that evolved into modern mammary and sweat glands; and genes, which control our eyes and ears, that correspond directly to DNA found In primitive jellyfish. If in any case the real values of his book goes beyond biology. …show more content…
The latter notation, brainchild of fundamental Christians, argues that the complexity of life on us cannot be explained without recourse to intelligent designer, in other words God. By the information acquired by reading this book, it seems that if the miracle of life on earth was designed by a greater power, "God", he or she did not do an immaculate job. Because if life on earth was perfectly designed, there would be no such thing as infections, illnesses, or even widespread
