*Africans carved the world’s first colossal sculpture 7,000 or more years ago. The Great Sphinx of Giza was fashioned with the head of a man combined with the body of a lion. How old is it? In October 1991 Professor Robert Schoch, a geologist from Boston University, demonstrated that the Sphinx was sculpted between 5000 BC and 7000 BC, dates that he considered conservative.
The human race is of African origin. The oldest known skeletal remains of anatomically modern humans (or homo sapiens sapiens) were excavated at sites in East Africa. Human remains were discovered at Omo in Ethiopia that were dated at 195,000 years old, the oldest known in the world.
Africans pioneered basic arithmetic 25,000 years ago. The Ishango bone is a tool handle with notches carved into it found in the Ishango region of Zaïre (now called Congo) near Lake Edward. The bone tool was originally thought to have been over 8,000 years old, but a more sensitive recent dating has given dates of 25,000 years old. On the tool are 3 rows of notches. Row 1 shows three notches carved next to six, four carved next to eight, ten carved next to two fives and finally a seven. The 3 and 6, 4 and 8, and 10 and 5, represent the process of doubling. Row 2 shows eleven notches carved next to twenty-one notches, and nineteen notches carved next to nine notches. This represents 10 + 1, 20 + 1, 20 - 1 and 10 - 1. Finally, Row 3 shows eleven notches, thirteen notches, seventeen notches and nineteen notches. 11, 13, 17 and 19 are the prime numbers between 10 and 20.
