According to evolutionist Charles Darwin, monkeys and humans have a common ancestor they evolved from. This is perhaps one of the reasons monkeys and humans have so many things in common, from the look to certain aspects of their behaviour. Scientists have studied the behaviour of monkeys, especially in chimpanzees and gorillas and have came to the conclusion that they share more than 98 percent of the human genetic code. They are highly intelligent and social beings who have their own language and their distinct cultures. This particular species of monkeys use tools, teach their young, plan for the future and make moral choices.
Monkeys held in captivity have been taught American Sign Language and their proficiency shows that they can understand and use abstract symbols in their communication. Researchers have also proven that the line that separates monkeys from humans and from the rest of the kingdom has been arbitrarily drawn. Researchers and doctors have also used monkeys in developing communication skills in children. It is a proven fact that chimpanzees can pass on these acquired skills onto their children.
Unfortunately, there are many monkeys that have been used for all kinds of experiments. There are many organisations and associations that struggle to put an end to these experiments. Chimpanzees are used today predominantly in infectious disease experiments, most commonly hepatitis and AIDS. Once infected with the virus, these monkeys often remain isolated from other chimpanzees and confined indoors for life.
Today, there are many projects that support freeing monkeys held in captivity or using them in medical assistance. Some organisations, train capuchin monkeys as monkey helpers to assist quadriplegics and other people with severe spinal chord injuries or mobility impairments. After being socialised in a human home as infants, monkeys undergo extensive training before being placed with a quadriplegic. Around the house, monkeys are trained to perform daily tasks such as heating the food in the microwaves, washing the face of the patient and opening drink bottles. Be that as it may, monkeys are animals and should live in their own natural habitat.
