Astronomy FAQ.

Likely over 2 million humans roamed Africa, the Middle East, Europe, and Asia in 300,000 BCE. Traditionally anthropologists focus on the DNA of direct-line Homo sapiens, and estimate the population from a low of 10,000 to a high of 300,000. But sapiens were just one of the many known ancient human species at the time and of our species, most did not extend their DNA. The fact is, the way we look at ancient humans is evolving. 

This pivotal moment in prehistory marks the emergence of Homo sapiens, yet they were just one of many players on the ancient stage. The population of Homo sapiens in Africa during this era was likely in the hundreds of thousands, while other ancient humans contributed to the broader estimate of over 2 million. It has become pretty clear, the broader success of the tapestry of various ancient humans across the globe was flourishing more than ever. These various species, all in the genus Homo, go back at least 2 million years to Homo habilis and their descendant species. 

Unlike other non “Homo” hominid species, like chimpanzees and apes, which are generally limited to their native environments, ancient humans evolved a “pioneering spirit.” While humans need clothes to survive in many places, what truly sets us apart is this adaptability, our “pioneering spirit.” Our knack for venturing well beyond our native turf is unmatched. We’ve been rocking this trait since the days of Homo habilis, about 2.3 million years ago. As the Bangles would put it, we’re born to “roam around the world.”

30 Phil, Chapter 22: In this new look at Descartes thought experiment, we first take a look at his hyperbolic doubt, and then run his thought experiment a second time using rational doubt transforming his thought experiment from the irrational to the rational.

Astronomy Story.

Jul 1663

In July 1663, King Charles II granted a Royal Charter to the Colony of Rhode Island and Providence Plantations uniting Providence, Warwick, Newport and Portsmouth. It became the State of Rhode Island after the Revolutionary War. John Clarke, who stayed behind after Roger returned in 1654, worked hard and deserves much of the credit.
