ANCIENT WORLD
LAYING THE FOUNDATIONS
FOR CENTURIES THERE have been debates over what makes humans unique among the animals. Biologists frequently insist that there is nothing special about the species Homo sapiens. The term âexceptionalismâ is used in biology circles in a derogatory fashion to describe the attempt to give us a special status. And, certainly, there are few human abilities that arenât duplicated in some fashion by other animals. However, Homo sapiens far exceeds other species in its collective capabilities to adapt its environment for life, and the driver for this ability seems to be creativity.
This remarkable trait was present when Homo sapiens first evolved, over 200,000 years ago. Creativity means that humans do not simply accept things as they are and live in the present, but can think outside the moment and ask questions such as âWhy does that happen?â or âWhat if I did this?â or âWhat could I do to make things different?â
When early humans looked beyond scratching an existence to the full might of nature â from the Sun and the stars to the devastating power of lightning and hurricanes â the first responses to the question âWhy does that happen?â involved deities or magic. The assumption was that there had to be supernatural forces, capable of actions that were forever beyond our understanding, even if they perhaps could be placated by human rituals. However, with the establishment of static gatherings of people in the early cities, there was an opportunity to begin to take what we would now consider a more scientific approach.
First came the use of numbers (although arguably a separate discipline to science, mathematics is so tightly tied to the sciences that we will be considering it an integral part of Scientifica Historica). More accurately, what seems to have come first was the tally, a mechanism for counting that did not require numbers. Say, for example, a neighbour borrowed some loaves of bread and you wanted to make sure that your loaves were all replaced. Without numbers, you could put a pebble in a safe place for each loaf the neighbour took. When they handed over a replacement loaf, you would throw away a pebble corresponding to it until there were no pebbles left.
We donât know for certain how long such systems were used as they leave no permanent record, but a number of ancient bones have been discovered that appear to have tally marks on them. The Ishango bone, which is over 20,000 years old, is a baboonâs leg bone, found on what is now the border of Uganda and the Democratic Republic of the Congo. It has a series of notches carved into it, which are widely interpreted as being a tally. The even older Lebombo bone, dating back over 40,000 years, also has a series of notches, though there is more dispute about their nature.
Tally markers can preserve information remarkably well, as witnessed by the fact that these bones still exist so long after they were first created. Such bones can be considered the earliest ancestor of a written record. Of a similar age to the Lebombo bone are some of the early cave paintings, which provide another form of communication that had the potential to establish traditions across a period of time.
Keeping a long-term written record may not have had significance for the makers of the bone tallies, but as cities and trade grew, the need for accounting meant that records began to be kept. At the time, these may simply have been markers of financial transactions, however the ability to keep information to a later date, and to share it, would be crucial for the development of a scientific view of the world.

From tallies to writing
Over the centuries, straightforward pictures and simple notch-based tallies developed into pictograms. As the name suggests, pictograms were image-based, but unlike cave paintings they were stylised into a standard form to represent individual concepts. Some modern Chinese characters still take this form â the character for âdoorâ for example, looks a little like a door.
With some thought, pictograms could also be used to convey less concrete notions. For example, a series of pictograms could be used to communicate the process of putting bread into a basket. If we see a loaf of bread, then a hand, then a loaf in a basket, the message is fairly clear. (For a modern example of a message using pictograms, think of an IKEA instruction sheet.) In that basic form there is no separate symbol to display the concept of âinâ or âintoâ, meaning that we need an awful lot of pictograms. There would need to be, for example, a different symbol for a loaf in a basket and for a dog in a basket. But it is not hard to imagine something like an arrow being used to indicate the relationship of âinâ, after which we just need the pictograms for bread (or dog) and basket with that linking arrow image. A symbol such as this arrow i...
