Final answer:
Ashley Montagu did not identify a specific number of racial groups in his typological matrix. Race is a social construct and there is no biological basis for dividing humans into discrete categories.
Step-by-step explanation:
Anthropologist Ashley Montagu did not identify a specific number of racial groups in his typological matrix. It is important to note that the concept of race itself is not scientifically valid. According to biologists and geneticists, race is a social construct and there is no biological basis for dividing humans into discrete racial categories. Human traits, such as skin color, hair texture, and blood type, vary along a spectrum and do not neatly align with traditional racial categories.
