Humanity has evolved primarily to deal with its environment and to learn how to interact and compete with itself. This means that human intelligence, discernment and capability have evolved largely in response to living in the natural environment and in dealing with other human beings.
There are very many people throughout the world today that feel a great change is upon humanity. They base this not only upon the substantive change they see in their societies and cultures, but also in terms of their deepest feelings. Some are hopeful; many are fearful; some only speculate that greater rewards and success await humanity, while others forecast a great calamity is coming.
