The expansion of consciousness
Competition stems from animal behaviour and is originally aggression. In
nature aggression guarantees that vigorous creatures defeat the weak ones. Human
beings learned how to use tools so that they could survive, without developing
the same physical strength as the beast of prey. Bow and arrow were necessary to
kill animals. Using tools man no longer lived in a state of nature, but was able
to conquer nature.
Research work has shown that humans by shooting and eating animals ingest
high-protein food, which increases brain capacity, while leaves and other
vegetarian food keep the brain capacity low.
Mentality of the human beings thereby changed. Watchfulness caused new solutions
of sheltering and preparation of food. They learned how to make use of fire, and
how to store food. And consciousness improved.
In the course of time many other technological conquests appeared. Among
the path-breaking inventions that crucially changed the existence of the people
of that age was the plough, which made it possible thoroughly to cultivate the
earth, using oxen as tractive force. Subsequently the wheel was invented, making
transport of stones and heavy equipment possible. The time frame is long.
The brains of humans are more developed than the brains of other mammals. The
cerebral cortex is much bigger than at any other animal. Different parts of the
brain have got common features with different species of animals, a very
fascinating study. Humans are endowed with the power of abstraction, meaning the
ability to express themselves. They can understand the surroundings, taking
changes into account, and they are socially minded, the foundation of culture.
No other creature has been able to accumulate knowledge and to work up
experiences into new behaviour.
