On the Edge of Discovery
The leading center for the science of human origins
bottom-left
The Institute of Human Origins is one of the preeminent research organizations in the world devoted to the science of human origins
A research center of the College of Liberal Arts and Sciences (link is external), IHO pursues an integrative strategy for research and discovery central to our founding mission. We bridge social, earth, and life science approaches to the most important questions concerning the course, causes, and timing of events in the human career over deep time.
IHO fosters awareness of human origins and its relevance to modern society through innovative outreach programs that provide timely, accurate information for both educators and the general public.

Upcoming Trips and Events
Grand Canyon River Rafting Expedition
May 26–June 2, 2019
Are you ready to go? Float the Colorado River though the Grand Canyon with the ASU Institute of Human Origins!
IHO has secured two boats for a week-long trip down the Colorado River guided by two ASU geologists—Chris Campisano PhD and Ramon Arrowsmith, PhD.
The trip will begin at Lee's Ferry and travel on quiet, motorized rafts from mile 0 to mile 187, where you will helicopter out to return to your car at Lee’s Ferry or catch a small plane back to the airport in Las Vegas. Reserve your spot today!
Outreach
From our very beginning, the Institute of Human Origins focused one "leg" of our mission on public outreach. Our founding members believe that scientists are the best interpreters of their own research for the public. Our research is human history, and we believe that sharing the story of how we "became human" with the public is as important as sharing the science.
Becoming Human
Becoming Human is a Webby award-winning and American Association for the Advancement of Science approved website, and one of the ways we teach paleoanthropological science to online users of all ages.
Ask An Anthropologist
Inspired by Ask A Biologist and our Webby-award winning website Becoming Human, Ask An Anthropologist aspires to build an online community of science and social studies educators focused on middle- and high-school learners.
Many resources on the web provide facts about how we became human, but we provide classroom teachers with curricular tools and content that engage young people in human origins and scientific methods.
