what have scientists concluded about the deepest splits in the human family?
a the deepest splits are between people who live near the equator and those who live near the poles.
b the deepest splits are between african populations such as the khoe - san and the pygmies.
c the deepest splits are between different races like white, black, and asian people.
d the deepest splits are between humans and neanderthals.

Explanation:

• Option A: Latitude - based splits (Equator vs poles) aren't the deepest human family splits, as human genetic diversity's deepest roots are in Africa, not based on this geographic division.
• Option B: Genetic and anthropological research shows that the deepest splits in the human family tree are among African populations like the Khoe - San and Pygmies, as Africa is the origin of humanity and these groups represent some of the oldest lineages.
• Option C: The concept of "races" as distinct genetic groups is not supported by modern genetics. Human genetic variation is continuous, and the idea of distinct racial splits is a social construct, not a scientific conclusion about deep human family splits.
• Option D: Neanderthals are a different hominin species, and the split between humans (Homo sapiens) and Neanderthals is not the "deepest split in the human family" (the human family here refers to Homo sapiens lineages). The deepest splits are within Homo sapiens, among African populations.

Answer:

B. The deepest splits are between African populations such as the Khoe - San and the Pygmies.
