Human Evolution Relevance
The northern muriqui has been argued to be important to understanding human evolution, since it is one of the few primates that has tolerant, nonhierarchial relationships among and between males and females, a feature shared with hunter-gatherer humans, but which contrasts with the ranked relationships of most other primates. Group aggression is also rare. The success of males fathering offspring links to the maternal investment they gain from their mothers and coresident female kin. This provides support to the grandmother hypothesis.

Famous quotes containing the words human, evolution and/or relevance:
“A creature not too bright or good
For human natures daily food;
For transient sorrows, simple wiles,
Praise, blame, love, kisses, tears, and smiles.”
—William Wordsworth (17701850)
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial universally human images lie dormant. Those primordial images are the most ancient, universal and deep thoughts of mankind. Since they embody feelings as much as thought, they are properly thought feelings. Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)
“... whatever men do or know or experience can make sense only to the extent that it can be spoken about. There may be truths beyond speech, and they may be of great relevance to man in the singular, that is, to man in so far as he is not a political being, whatever else he may be. Men in the plural, that is, men in so far as they live and move and act in this world, can experience meaningfulness only because they can talk with and make sense to each other and to themselves.”
—Hannah Arendt (19061975)
