Why do we look the way we do? Neil Shubin, the paleontologist and professor of anatomy who co-discovered Tiktaalik, the â??fish with hands,â?쳌 tells the story of our bodies as you've never heard it before. By examining fossils and DNA, he shows us that our hands actually resemble fish fins, our heads are organized like long-extinct jawless fish, and major parts of our genomes look and function like those of worms and bacteria. Your Inner Fish makes us look at ourselves and our world in an illuminating new light. This is science writing at its finestâ??enlightening, accessible and told with irresistible enthusiasm.
