Homologous structures are shared anatomical features found in

The human esophagus and trachea share a passage leading from the mouth and nasal passages, which can cause problems. After reviewing vertebrate evolution in chapter 34, explain the evolutionary basis for this "imperfect" anatomy.

All vertebrates (including humans) share all of the following anatomical traits except: a body plan that is composed of an inner tube surrounded by an outer tube the left half of the body is essentially a mirror image of the right half a set of 4 limbs that are paired in both structure and function there is a hollow nerve cord running along the back O pouches in the throat that correspond to the clefts between the gills of fish Question 5 The human anatomical position includes all of the following except: the subject is lying down the toes are facing forward the thumbs point away from the body the palms of the hands are facing forward the face are looking forward
