The fact that the development of individual areas of the brain are highly variable is proven by
comparative brain studies among animals. Brains are extremely complex. The brain has individua
areas demarcated for vision (visual), hearing (auditory), taste (gustatory), and smell (olfactory). The
bigger the individual area, more pronounced is its corresponding function. Compared to dogs and
wolves, the relative size of the olfactory area of a human brain is smaller, while the human brain's
visual area is more pronounced. Dog breeds not only show differences in outward appearances
but also show variations in their relative volumes of the olfactory lobe. This explains why some
breeds alone are suitable for police functions like scent detection. The German Shepherd, Belgian
Malinois, and Beagle are the popular ones with the police.
What can we infer from comparative brain studies?
The brain has individual areas demarcated for vision, hearing, taste, and smell
