Why are humans classified in the family Hominidae?
Humans are classified in the sub-group of primates known as the Great Apes. Humans have bodies that are genetically and structurally very similar to those of the Great Apes and so we are classified in the Great Apes sub-group which is also known as the hominids (Family Hominidae).
