Humans who are alive during the 21st century, 13.7 billion years of evolution after the ‘big bang’, are extraordinarily fortunate. The shift to intentional evolution is one of the most significant evolutionary transitions that can occur on any planet on which life emerges. We have the unique opportunity to contribute to its successful completion on this planet. And if we choose to make this contribution, we will do so consciously—we will be aware that we are contributing intentionally to the successful completion of a pivotal evolutionary event on this planet.
