Social Behavior Among Monkeys May Be More Nature Than Nurture
ScienceDaily (Dec. 4, 2003) — An unusual experiment with monkeys who were switched between mothers shortly after birth has demonstrated the importance of nature over nurture in behavior.
Young monkeys reared by a mother other than their own are more likely to exhibit the aggressive or friendly behavior of their birth mothers rather than the behavior of their foster mothers, a University of Chicago researcher has shown for the first time.
The discovery of inheritability of social behavior traits among non-human primates has important implications for people as it reinforces other research that suggests that such characteristics as sociability and impulsive

There might be a variation in the number and sizes of these groups depending on the abundance of preferred food available. Read on to know more about the Spider monkeys behavior
These groups of spider monkeys will wander independently in the same general area. The only constant association observed is that of a female with her offspring. The females play a more active and leading role than males. Parallel to the species food requirements, a kind of social system seems to have evolved amongst these spider monkeys. According to new research and studies, a leading female seems to take a well planned route in advance. These routes are not only highly economical, but can also vary greatly from day to day, according to the needs of the troop. Earlier it was thought that the daily feeding routes were always the same.
When studying the behavior of Spider monkeys, it has been seen that males were not as apt as the leading females in planning an economic and varied food route. Therefore they tend to have a less varied diet. Incase of the scarcity of the food, the groups avoid overlapping territories.
Spider monkeys at night use trees for sleeping. These trees are usually tall enough with horizontally forked branches for extended resting postures. These sleeping trees are also chosen for their ability to give a ready supply of food and also for the safety from predators. If threatened by any predators, it is seen that both males
