While there is no practical limit on what types of people can form a friendship, friends tend to share common backgrounds, occupations, or interests and have similar demographics.
Approximately 800,000,000 humans live in the Southern Hemisphere, representing only 10â12% of the total global human population of 7.3 billion. This is due to the fact that there is significantly less land in the Southern Hemisphere than in the Northern Hemisphere.
The largest primate in the Western Hemisphere is the woolly spider monkey called. muriqui. It is one of the most endangered of all primates and it lives along the. Brazilian coast. There are only 300- 400 woolly spider monkeys left in the world. Their near demise has resulted because of their forest habitat has been nearly. removed by loggers and those seeking farmland to grow food. Studies of the woolly spider monkey have discovered that they have a unique social. system. In a study group of 26 individuals continuously observed over 14 months, scientists found an extraordinary degree of cooperation and friendship among males.
