The Arnold Arboretum of Harvard University is a community resource for education, offering a variety of learning opportunities including lectures, classes, workshops, and tours of our living collections and historical landscape. Join us as we explore the biology and horticulture of woody plants, and delve into topics related to Earth’s biodiversity and evolutionary history, the environment, conservation biology, and key social issues associated with current science.
Unnatural Selection: How we are changing life, gene by gene
Emily Monosson, PhD, Environmental Toxicologist and Adjunct Professor, University of Massachusetts, Amherst
1 Session: Wednesday, January 28, 7:00–8:30pm
Location: Hunnewell Building
Weeds. Bed bugs. Gonorrhea. Salamanders. People. All are evolving, some surprisingly rapidly, in response to our chemical age. Emily Monosson, toxicologist and author of Unnatural Selection, shows how our drugs, pesticides, and pollution are exerting intense selection pressure on all manner of species. And we humans might not like the result. When our powerful chemicals put the pressure on to evolve or die, beneficial traits can sweep rapidly through a population. Species with explosive population growth—the bugs, bacteria, and weeds—tend to thrive, while bigger, slower-to-reproduce creatures, like ourselves, are more likely to succumb. Exploring contemporary evolution, Monosson examines the species that we are actively trying to beat back, from agricultural pests to life-threatening bacteria, and those that are collateral damage—creatures struggling to adapt to a polluted world, and shows how environmental stressors are leaving their mark on plants, animals, and possibly humans for generations to come.
