A comparison between the Paleolithic Australian Aboriginal people and Native American Indians encountered by the arrival of Europeans during the beginning colonization of Americas was different. To this day, there still remains several groups that practice exactly  the same cultural and religious traditional ways of life. These groups of Australian Aborigines are not included or seen in the general public, because they are extremely, going to great lengths to secure their private and spiritual belief system. Only in the 1970's, contemporary Australian Aboriginal art started to incorporate their early art (only sections are allowed for public viewing) with modern art to create a whole new entity of abstract images representing messages, emotions, and symbols.
