Adaptation and Speciation in California Monkeyflowers
Doug Schemske, PhD, Plant Biology Professor, Michigan State
Our research team investigates adaptation and speciation in two closely related species of California monkeyflowers (Mimulus) that differ in their mode of pollination. Mimulus lewisii is found at high elevation in the Sierra Nevada and is pollinated by bees, while its close relative, Mimulus cardinalis, is found at low elevation, and is pollinated by hummingbirds. Our team has employed field experiments and molecular genetic techniques to identify the adaptive steps in the evolutionary trajectory from bee to hummingbird pollination. We find strong evidence that large genetic changes have contributed to the evolution of the pollination system, a view consistent with new theoretical insights into the mechanisms of adaptive evolution
