Center forHuman Evolution and Diversity

There is an urgent imperative to unbias human microbiome studies across the diversity of all of us to solve the major challenges relating to health disparities and inequities. More precise and personalized approaches must take into account microbial influences on and responders to our lived experiences. Without a sense of urgency and mission, the generalizability of microbiome findings across populations will be limited and likely generate new cascading health disparities.

Seth Bordenstein, Director of the Microbiome Center, Professor of Biology and Entomology

Reconstructing human ecosystems of the past and their evolution provides not only a window into the past but helps us better plan for the future. We can use information from our ancestors to improve our lives tomorrow.

Laura Weyrich, Associate Professor of Anthropology

Quite simply, the only way we will make meaningful progress in solving “wicked problems” of today and tomorrow is to take a holistic approach, drawing upon both depth and breadth of expertise from multiple disciplines and recognizing the importance of diverse perspectives and experiences.

Jennifer Wagner – Assistant Professor of Law, Policy, and Engineering

One of the strongest evolutionary influences on humans has been largely invisible: microbes. Interdisciplinary approaches that incorporate evolution, microbiology, genetics, physiology, and more are necessary to reveal how we interact with microbes and how these trans-kingdom interactions affect both evolution and health.

Emily Davenport – Assistant Professor of Biology

Our history of conquest, colonization, and massive forced migration has created a profound and long-lasting social and cultural legacy, and these actions also left a genomic legacy. Transdisciplinary research is necessary to fully appreciate human diversity, to combat health inequity, and to advance wellbeing for everyone.

Zachary Szpiech – Assistant Professor of Biology

"No factor is more fundamental to human variation than biological sex, and its importance to our health and well-being is becoming increasingly appreciated. A transdisciplinary approach rooted in evolutionary principles is the surest path to understanding the development of sex differences and how these processes contribute to human diversity and influence our lives."

David Puts – CHED Co-Director, Professor of Anthropology

"Our Center is important for two reasons: 1) There are many interesting questions yet to answer about human evolution and physical, behavioral, and genetic variation, and 2) There seems to be a continuing divide between what anthropologists know and how they think about human evolution and diversity and how the general public and academic colleagues in other fields think about these topics."

Mark Shriver – CHED Co-Director, Professor of Biological Anthropology

"Human beings are products of rich and complex interactions between biology and culture that have developed over millions of years. Human evolutionary history informs our understanding of human behavior and culture, and vice versa. Examining only one side of this set of reciprocal interactions risks missing the plot entirely."

Nina Jablonski – Atherton Professor, Evan Pugh University Professor Emerita of Anthropology

“Bringing together multiple disciplines to understand how people learn and reason about complex topics such as human evolution is important for today’s schools, museums, and other educational settings. The Center offers multiple perspectives of how research in this area is conducted, which will enhance young people’s views of how scientific knowledge is developed and of human diversity.”

Heather Toomey Zimmerman – Associate Professor of Education

"If we are to make any headway in fighting diseases, reducing inequalities and the internecine fighting that appears to emerge so endemically when resources are scarce, values differ, and political approaches conflict, we must utilize multiple approaches, methods, be transdisciplinary and take into account the nature of human diversity, at every level, from our genes to our social identifications."

Peter Hatemi – Professor of Political Science

"For problems ranging from infectious disease to racial tensions in American cities, understanding that evolution matters but that genes are not deterministic and differ in their effects depending on social behavior and environment is a powerful way to better understand and solve many human challenges. Interdisciplinary research holds great promise for using our knowledge of evolution effectively to improve the human condition."

Eric Plutzer – Professor of Political Science

"A transdisciplinary study of human evolution and diversity not only helps us understand how and why we became who we are, it is necessary for determining how we function day-to-day. My research examines the effects of biological and self-reported indicators of daily stress on health. How we experience and respond to daily life challenges is intricately tied to the evolution of human diversity."

David Almeida – Professor of Human Development and Family Studies

2023 Darwin Day Step Challenge

2023 Darwin Day Step Challenge

Can you be the fittest?

How many steps do you take in a day? How does your activity affect your sleep habits? Stress levels? Appetite?

As part of the 2023 Darwin Day Lecture by Herman Pontzer, CHED (with help from Sam Muller) organized a Step Challenge for students to see how they would match up to the Hadza, a group of nomadic hunter-gatherers in Tanzania.

Teams and individuals used their own fitness tracking devices and apps to log daily steps for the week of January 30 – February 5, 2023. Surveys were administered to participants that allowed them to examine and track daily stress levels, sleep habits, and appetite. Winners in team and individual categories were announced by Dr. Pontzer at the Darwin Day Lecture.

All together, the 82 Step Challenge participants walked 4,670,000 steps, about 2,000 miles. That’s like taking a stroll around the diameter of the moon!
