Harlow was researching the primates at the Henry Vilas Zoo‚ to study learning and memory in monkeys. While doing this Harlow discovered something very interesting‚ the monkeys were starting to develop strategies for Harlow’s tests that he set up.

There are many physical and psychological characteristics that all human beings‚ across cultures‚ display today that have evolved from our ancestors‚ over thousands of years. As a result of the selection process‚ we have adapted in particular

Without this system the ability to function and maintain a healthy lifestyle would be impossible. Correct posture‚ locomotion‚ and movement of internal organs are reliant. Although this system is composed of hundreds of muscles‚ each has various parts that provide a specific function. The muscular system is composed of approximately 700 muscles. These in turn contain fibers
