Big history started with the Alpha Point, be it the Big Bang or Big Bounce, and resembles a huge ongoing evolutionary computing program running on the universal computer of sorts. As a rule, which I refer to as ‘Universal Evolutionary Doubling Algorithm,’ or simply ‘Exponential Evolution,’ the pace of any evolutionary process always quickens It took billions of years since the Big Bang for Earth to form. It took two billion more for unicellular life to “warm up” for the next phase of multicellularity about 550 million years ago. Mammals inherited Earth some 65 million years ago. With the emergence of primates, evolutionary progress was measured in mere millions of years, leading to Homo sapiens some 300,000 years ago.
