Dear Sir,
Your concept of development of language and mathematics are questionable. While evolution of information is well established, there is no proof of evolution of intelligence.
Without defining intelligence, you cannot even remotely equate ants with human beings. At any moment, our sense organs are bombarded by a multitude of stimuli. But at any instant only one of them is given a clear channel to go up to the thalamus and then to the cerebral cortex, so that like photographic frames, we perceive one discrete frame at every instant, but due to the high speed of their reception, mix it up - so that it appears as continuous. Unlike the sensory agencies that are subject specific (eyes can only receive electromagnetic radiation, ears only sound, etc.); the transport system within the body functions for all types of sensory impulses. The same carrier transports the external stimuli from sensory agencies to the cerebral cortex and back as a command. This carrier is the mind. The existence of mind is inferred from the knowledge or lack of it about external stimuli. Only if the mind transports different external impulses to the brain for mixing and comparison with the stored data, we (Self) know about that (for the first time impulse received about something, there is no definite 'knowledge'). It requires an agent to mix these signals and convert them to electro-chemical information and submit to a conscious agent (operator) to cognize and utilize them. In perception, this task is done by a transitory neural activity in brain called intellect. Though, it is not directly perceptible, it is inferred from its actions - firing of positrons in specific areas of brain during perception. Each individual can develop his intelligence by learning from others, but there is nothing like collective intelligence - like a group performing a physical task, which is linearly additive.
The people who constructed pyramids were not primitive. Before 3500 BCE, in India each letter of the alphabet was pronounced in at least 18 different ways and the meaning of the word depended on the specific pronouncement. Hence it was not written. There are highly codified formulas for this, which are still available. One book written by Panini is referred to by computer professionals even today for developing programming. All modern Indian grammars follow those methods in a much diluted format. Those people developed the number system including zero and also had mathematical treatises including highly developed geometry (called Shulva Sootra). At around 4th Century BCE, Chanakya in India compiled the earlier works on Statecraft and Economics, which is treated as authoritative even today. Please do not denigrate our ancestors.
