Palaeontologist Neil Shubin will be familiar to many people for his co-discovery of Tiktaalik roseae, the "fishapod" which remains one of the icons of tetrapod evolution. Shubin is also well-known for his popular science book Your Inner Fish which is an accessible overview of the long trail of human evolution, showing why our anatomy, physiology, and genetics makes sense only in the light of evolution.
