First Edition, of one of Darwin’s lesser-known discoveries. Darwin was the first to postulate, in this paper, the existence of an inertially-based navigational system in animals; his suggestion was confirmed by studies done in the 20th century. This type of navigational system, now known as path integration, uses input from the vestibular organs and other sensors in the body to enable an animal, such as a migrating bird, to estimate its position with relation to its home.
