Questions and Answers
What general understanding about amounts did prehistoric ancestors possess?
Prehistoric ancestors had a general sensibility about amounts and instinctively knew the difference between one and two.
What significant intellectual leap concerning numbers took ages to develop?
The leap from the concrete idea of two things to the invention of a symbol or word for the abstract idea of 'two' took many ages to develop.
Why do some isolated hunter-gatherer tribes have limited number words?
Some isolated hunter-gatherer tribes have words only for 'one', 'two', and 'many' due to the absence of settled agriculture and trade, which reduces the need for a formal number system.

Study Notes
Prehistoric Number Conceptualization
- Prehistoric ancestors had an intuitive understanding of quantities, recognizing the difference between one and two animals.
- Transitioning from concrete counting to abstract concepts represented by symbols took significant time.
- Some contemporary hunter-gatherer tribes in the Amazon only have terms for "one", "two", and "many", while others have words for numbers up to five.
Early Counting Evidence
- Lack of a formal numbering system due to absence of settled agriculture and trade.
- Early humans tracked occurrences like moon phases and seasonal changes.
- Notched bones from Africa, dating back 35,000 to 20,000 years, represent some of the earliest evidence of counting.
Ancient Societies and Mathematics
- Pre-dynastic Egyptians and Sumerians created geometric designs as early as the 5th millennium BCE, emphasizing artistic rather than mathematical practices.
- Megalithic societies in northern Europe also exhibited geometric designs around the 3rd millennium BCE.
- The Ishango bone from central Africa, approximately 20,000 years old, is an early counting tool.
Development of Mathematics
- Formal mathematics arose largely in response to bureaucratic needs of settled civilizations for land measurement and taxation.
- Mathematics first developed in Mesopotamian cities and ancient Egypt.
- Evidence of basic arithmetic and geometric notation on petroglyphs in Ireland from 3500 BCE to 3200 BCE illustrates early mathematical practices.
Cultural Mathematics and Stonehenge
- Knowth and Newgrange burial mounds feature zigzag glyphs used for counting, with this system continuing into the 1st millennium BCE in Britain and Ireland.
- Stonehenge, dating around 2300 BCE, displays use of 60 and 360 in its circular measurements, possibly unrelated to the Sumerian sexagesimal counting system.
