m intelligence. Accor!
             ding to numerous publications, the term intelligence can be employed to indicate the amount of knowledge available and the rapidity with which new knowledge is acquired; the ability to adapt to new situations and to handle concepts, relationships, and abstract symbols. While the heredity/environment topic continues to be a controversial issue, a great deal of evidence has been gathered to support both arguments. In order to investigate the topic of nature/nurture it is important to consider a variety of research elements. Among these elements are some of the most relevant issues pertaining to this subject including: twin, adoption, family, orphanage life, IQ, and race studies. It is to these studies we will now turn our attention.
             The importance of twin studies is evident if we look at the studies objectively, if intelligence is basically hereditary, identical twins who have the same genetic legacy, should be concordant for that trait than are fraternal twins, which are no more alike genetically than other siblings. One famous study shows that the intelligence test scores of identical twins, whether reared together or apart, display considerably higher correlation than the scores of fraternal twins. The work is currently viewed with caution due to the manner in which he gathered and interpreted his data. However, this research provides an important foundation for this research. Another study shows that there is a modest difference in the intelligence test scores of twins reared apart, and the more divergent the environments, the greater the difference. While environmental factors are important in raising or lowering a child's level of intellectual performance, these studies demonstrate that !
