The who, what, when and where in speech evolution.
The outer ear and tiny ossicles (ear bones) - based on two observations: 1. Fossil reptiles. 2. Embryonic changes in living animals. As observed In embryos, two of the ossicles (hammer and anvil), begin as cartilage attached to the back of the embryonic jaw. So the large jawbones of our reptilian ancestors evolved into our tiny earbones. Fascinating.
