What is human biological variation? Briefly examine various somatoscopic characters to study biological variation. 

Human biological variation refers to the diversity and differences observed in the biological characteristics of individuals within the human species. These variations can be studied and observed through various somatoscopic characters, which are physical traits or characteristics that can be visually examined or measured. These traits provide insights into the genetic, environmental, and evolutionary factors that shape human populations. Here, we will briefly examine some of the key somatoscopic characters used to study biological variation.

1. Skin color: Skin color is one of the most visible and widely studied somatoscopic characters. It varies across human populations, ranging from very light to dark pigmentation. Skin color is influenced by genetic factors, particularly variations in the production and distribution of melanin, as well as environmental factors such as sunlight exposure.

2. Hair color and texture: Hair color and texture also exhibit considerable variation among human populations. Hair __________ ____ _________ ______ _______ __________.
