What is taking so long? The events that took place in order to come up with our home, Earth, are said to be a natural consequence. It is believed that it will never happen again, at least not in the lifetime of our planet. Andrew Watson, a professor of environmental science at the University of Reading, reports that there are four steps that are critical for a path to life. Those four steps are the development of primitive life, the rise of sex, cell specialization, and intelligence. Watson states that it is nearly impossible to reach those four steps all at the same time, making it impossible for life on other planets or
