Science @ the Hub: Human Evolution

The Global Dispersal of Homo Sapiens and the Archaeology of Computational Complexity

Dr. John Hoeffecker, from the Institute of Arctic and Alpine Research at the University of Colorado Boulder was November’s featured speaker for the science talk.

The Hub specializes in creating moments and situations where folks representing diverse viewpoints and backgrounds mingle.  The exchange of ideas is essential to culture and society and at the Hub we do our part to help in the free flow of ideas.

Dr. Hoeffecker’s talk was wide ranging and deep and possessed a great deal of interaction with the event’s attendees.  He took all questions seriously which helped make the talk feel more like a conversation.

Below is an excerpt from elsewhere on secularhub.org, copied and pasted here because they say it better than I ever could:

Anatomically modern humans (Homo sapiens) dispersed out of Africa several times after 300,000 years ago, but only one of the dispersals (beginning ~60,000 years ago), was ultimately global in scope, including Australia, the Eurasian arctic, and Western Hemisphere. The global dispersal entailed occupation of habitats and climate zones never previously occupied by earlier forms of Homo, probably because of relatively low plant and animal productivity and extreme winter temperatures. Adaptation to these habitats and climates required technologies of structural and functional complexity
comparable to those of recent hunter-gatherers in similar settings, including mechanical artifacts and insulated clothing. Archaeological evidence of such technologies is found in Africa after ~100,000 years ago and associated with the spread of modern humans into Eurasia and beyond. The quantum jump in technological complexity suggests an
increase in the complexity of the computations that underlie the design of artifacts, which in turn suggests that changes in human cognitive faculties underlie the global dispersal of Homo sapiens.

Building a Moral Foundation: Moral Landscaping Part 1 Episode 72

In this week’s episode your host Paul Schilling looks to set the foundation of a useful and functional moral code. In doing so he discusses the main cornerstones to a useful moral code: the subjective elements, the objective elements, the moral continuum and basic human rights. After listening to this episode you should have a clear understanding of the moral framework Paul sets out and how to use it in your life. This is the first part of a multi part series where Paul will focus on the different elements of a useful moral code. Future episodes will focus on basic human rights, modern day mythology, clarification of the moral code and deep dives where we answer moral questions. The goal of this podcast is to give the listener a solid moral foundation from which to build on and use in real world situations.

Satanic – Episode 71

From time to time we are lucky enough to experience a true cultural shift.  These shifts represent changes to the old ways of acting and thinking, and they can sweep away old, outdated ideas and replace them with the NEW.

Today on the Secular Hubcast we are very proud to present an event which took place where we welcomed members from The Satanic Temple of Colorado into our midst.  These Satanists very generously shared their time and insight with the Secular Hub community in a fantastic event that helped to show how alike we all really are.  Please enjoy.

This was a Humanism at the Hub event.  Check out the next upcoming event on meetup
