Regeneration is a remarkable phenomenon in which an animal can regrow parts of its body that are lost or damaged by injury. Humans, for example, can repair some organs, but some animals can rebuild their entire bodies from small pieces of tissue. How do these animals accomplish this feat? And why is it that humans cannot regenerate as well as these animals can? Studies of how regeneration works at the molecular and cellular level are beginning to answer the first question. To answer the second question, we have to understand how regeneration has evolved.
Visitors to the Harvard Museum of Natural History are dazzled by the Mineral Gallery’s beautiful specimens, yet the gallery displays only a fraction of the entire collection.
While each of the collection’s 300,000+ specimens has great scientific value, a subset also has significant commercial value. Join Curator Raquel Alonso-Perez for a virtual behind the-scenes visit to view specimens that, for security reasons, are not typically on display. You’ll see a rare opal in matrix from Mexico, tourmalines from the first pegmatitic discovery in the U.S., and crystalline gold, among...

Humans are living longer lives than ever before and so it is critical to understand the process of aging. It has become increasingly recognized that successful aging is not just about physical health but also about our social lives.
Chimpanzees are our closest living relative and also lead long and complex lives. In this talk, you’ll learn what chimpanzee aging can tell us about human aging.

The first person who will set foot on Mars is alive right now. We believe this, but even if we're wrong we know the first crew to arrive there will look nothing like the ones that landed on the Moon fifty years ago.
Our world has changed for the better, and ASTRONAUTS tells the story of the women who built this better world. The main character and narrator is Mary Cleave, an astronaut you may not have heard of. It's not because so many people have been to space; only a few hundred have! It’s because this graphic novel isn’t about fame. No astronaut you'll ever meet took the...
Earth is home to a vast diversity of organisms that collectively define the modern biosphere. How did this diversity come to be? Javier Ortega-Hernández will discuss his approach to answering this question by studying organisms that lived more than half a billion years ago in the Cambrian Period (485–541 million years ago). By focusing on the earliest-known animals—some of the most versatile to ever exist—Ortega-Hernández aims to reconstruct the early evolutionary history of major animal groups and contribute to our understanding of Earth’s biodiversity.
Join the Harvard Museum of Natural History for a public lecture with Susan Alberts, Robert F. Durden Professor of Biology and Evolutionary Anthropology at Duke University.
The social environment—both in early life and adulthood—has major effects on human health and survival. But how and why does the social environment get “under the skin” to also affect our physical health? Susan Alberts pursues this question by studying wild baboons in Kenya. Baboons, like humans, evolved as savannah dwellers. They rely on social relationships to solve problems and—like humans...

Sam Jaffe, naturalist and educator, will present both the collaborative and deceitful nature of insects and plants as they’ve evolved to rely upon one another. This lecture, illustrated with Sam’s gorgeous photographs, will expand your invertebrate knowledge, appreciation, and desire to be the best garden host you can be.
What better place to look for the differences between angiosperms (plants that flower and have enclosed seeds), and gymnosperms (plants with "naked seeds," including conifers, ginkgos, and others), than in the Arnold Arboretum landscape, where over 15,000 plants reside in a living museum. Join our guide as she points out trees in both groups and describes the characteristics of each.

Historically, plants have provided humans with most of our drugs, fibers, food, dyes, perfumes, building materials, and even musical instruments. But how has this diverse and fascinating field been studied and what has been learned? In fact, for over 100 years, Harvard has played a pivotal role in the study of human-plant interactions, leading to the creation of the field of ethnobotany.
In this interactive lecture we will explore the science and history of some of the most important Harvard botanists and explorers through their unique specimens—now housed in the Harvard...

How does an egg become an egg? Why do chickens continue to lay eggs day after day? What controls the shape of eggs? Why do eggs of different species of birds have different colors? And how strong are eggshells?
In this talk which follows previous talks about bird flight, migration, and feathers, Lorna Gibson answers common questions about bird eggs.
Microbes play critical roles in the biology and health of human beings, but we are not the only species that benefits from intimate relationships with microbes. Ants, for instance, rely on the microbial communities living in their guts to process food and make strong armor.
Corrie Moreau will discuss this unique aspect of ant biology and what it tells us about the diversity and dominance of ants in terrestrial ecosystems, the evolutionary history of social insects, and the broad-scale evolutionary patterns of life.
Domesticated animals such as dogs, pigs, and horses often sport floppy ears, patches of white hair, and other features that are unknown in their wild ancestors. These traits—collectively referred to by scientists as a “domestication syndrome”—are the result of breeding less aggressive individuals.
Drawing from his new book, The Goodness Paradox (2019, Pantheon Books), Richard Wrangham will show that our cousin apes, the bonobos, also exhibit a domestication syndrome, making them the first clear example of a “wild domesticate.” Self-domestication in the wild now seems...
The Cape Cod white shark population has increased in recent years in response to the dramatic increase in the seal population. Shark sightings—some close to popular swimming and surfing beaches—are becoming more frequent and negative interactions between sharks and humans have become a real concern.
Gregory Skomal has studied and tracked white sharks in the Atlantic for more than 30 years. In this lecture, he will examine the behavior, ecology, natural history, and population dynamics of this species, and how scientific research can help sharks and humans coexist in the Cape...
