"Dolichocephalic" refers to a skull shape characterized by a long and narrow head. This term is often used in anthropology and biology to describe certain human populations and animal species. The measurement of the skull's length compared to its width determines whether it is classified as dolichocephalic. In humans, dolichocephalic individuals typically have a cephalic index (the ratio of the width to the length of the skull) of less than 75. This trait can be found in various ethnic groups and is sometimes associated with specific geographical regions. Understanding skull shapes, including dolichocephalic, can provide insights into evolutionary biology and human diversity.
