Answer :
Brain endocasts are used to estimate cranial capacity, but some scholars believe that they also may be used to understand the development of speech.
- When discussing the cranial vault in the study of how the brain develops in humans and other species, an endocast is a hollow object's interior cast. Endocasts can be created synthetically to study the characteristics of a hollow, inaccessible region, or they can form naturally through the process of fossilisation.
- The volume of the inside of the cranium in vertebrates—animals with a cranium and a brain—is referred to as cranial capacity. Cranial volume is used to roughly estimate brain size, which is also a sign of an organism's intellect. Larger capacities are seen as a trait of adaptability, but not always of superior intelligence, in larger animals and in colder habitats.
