Africa is a nation that unfortunatly has to deal with a lot of problems, problems that we couldn't even begin to address in the United States. But instead of helping Africa, we choose to ignore it. Some people even say that we shouldn't do anything about it and jst focus on our nation. Our government seems to also be ignoring the problems in Africa, choosing to go to places that offer them something better. But I would like to remind everybody of thing we wouldn't have if it weren't for Africa
Without Africa we wouldn't have...
Humans- The human race is of African origin. The oldest known skeletal remains of anatomically modern humans (or homo 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.
Math-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.
Crops-Africans cultivated crops 12,000 years ago, the first known advances in agriculture. Professor Fred Wendorf discovered that people in Egypt’s Western Desert cultivated crops of barley, capers, chick-peas, dates, legumes, lentils and wheat. Their ancient tools were also recovered. There were grindstones, milling stones, cutting blades, hide scrapers, engraving burins, and mortars and pestles.
Writing- In around 300 BC, the Sudanese invented a writing script that had twenty-three letters of which four were vowels and there was also a word divider. Hundreds of ancient texts have survived that were in this script. Some are on display in the British Museum.
Toilets and sewerage systems- existed in ancient Egypt. One of the pharaohs built a city now known as Amarna. An American urban planner noted that: “Great importance was attached to cleanliness in Amarna as in other Egyptian cities. Toilets and sewers were in use to dispose waste. Soap was made for washing the body. Perfumes and essences were popular against body odor."
Autopsies and caesarean operations- These procedures were routinely and effectively carried out by surgeons in pre-colonial Uganda. The surgeons routinely used antiseptics, anaesthetics and cautery iron. Commenting on a Ugandan caesarean operation that appeared in the Edinburgh Medical Journal in 1884, one author wrote "The whole conduct of the operation . . . suggests a skilled long-practiced surgical team at work conducting a well-tried and familiar operation with smooth efficiency.”
