Am having a wonderful time reading, “Your Inner Fish” by Professor Neil Shubin – an exploration into the deep evolutionary roots of the human body. Amazed to contemplate the embryonic structures known as the branchial arches, or gill arches – which we share with sharks! – and the role of the gcm2 gene that is expressed in these arches and controls salt balance in humans and fish. Pharyngula has a wonderful post on this !!
Hoping to find more deep evolutionary roots of mind and brain.
