"[1] Homo sapiens has many characteristics that show the biological specificity in the form of behavior and morphological traits.
Morphologically, humans have an enlarged cranial capacity[citation needed] and more gracile features in comparison to other hominins.
This is a uniquely human experience, as other animals are able to give birth on their own and often choose to isolate themselves to do so to protect their young.
[5] Humans do not simply communicate with a code or general understanding, but adhere to social standards, hierarchies, technologies, complex system of regulations and must maintain many dimensions of relationships in order to survive.
Intraspecific behaviors and variations exist within Homo sapiens which adds to the complexity of culture and language.
Variation in genetic expression of race and gender and complexities within society lead to social constructs such as roles.
