The Evolution of Humans
As with all life on the planet, the evolution of humans began in the vast oceans. They migrated to the land and continued to evolve as land animals. From small lemur type creatures, to monkeys, to man the evolution of humankind has been an interesting ride.
Humans have a large brain that is capable of complex reasoning and abstract thought. Humans are mammals that use sexual reproduction to produce live young. The young are helpless and are nourished and cared for by the mother and other members of the family, until they are grown.
The large brain of humans has enabled them to establish a complex verbal and written language. Audible sounds that are produced have been given meaning. As the language became more complex ideas and discoveries could be shared from one person to another with complete understanding (if not acceptance).
The development of written language helped to keep knowledge from fading away. A strictly oral language can cause knowledge to be corrupted and forgotten. By writing things on stone or paper, as long as someone knows how to read the language, the information is available until the stone or paper is destroyed.
Humans are pack animals, and they need a structure in order to function. Human society can vary greatly depending on where they live. Core family units, community, and leaders all play a role in how humans live and interact with one another.
Society and culture determines which behavior is acceptable. What one can do in one country may be taboo in another. When a human does not conform to the society that they live in, they can become outcasts. Outcasts from human society can survive, but their lives are normally not as healthy and happy, as those who live within the bounds set by the community.
Humans and the Environment
Humans change the environment around them to suit their needs. The beginning of this environmental adjustment was agriculture and the domestication of animals. The development of farming enabled larger and larger groups of people to be fed. As people came together in larger groups, larger communities were needed. This led to the building of cities, which in turn, led to industry and technological advancements.
