Darwin Day 2018: Charles Darwin, Evolution, and Finches
Wednesday, February 14, 2018 | 7 p.m.
Charles J. Dougherty Ballroom
Duquesne Power Center
Rosemary and Peter Grant Emeritus
Professors in Ecology and Evolutionary Biology
Join Drs. Rosemary and Peter Grant as they discuss the progress that has been made in our understanding of speciation with special reference to the young radiation of Darwin's Finches of the Galápagos Islands, drawing on the results of their long-term field study of finch populations spanning several decades, combined with laboratory investigations of the molecular genetic basis of beak development.
In the Origin of Species, Charles Darwin established the scientific basis for understanding how evolution occurs by natural selection. To explain how species form, he envisioned a three-step process: colonization, involving the expansion of a population into a new environment; divergence, when populations become adapted to novel environmental conditions through natural selection; and finally, the formation of a barrier to interbreeding between divergent lineages. He showed characteristic insight by suggesting that investigations of what we now call, "very young adaptive radiations" might provide windows through which we can view the processes involved. Since Darwin's time, insights from the fields of genetics, behavior and ecology have continued to illuminate how and why species evolve. In this talk, we will discuss the progress that has been made in our understanding of speciation with special reference to the young radiation of Darwin's Finches. We draw upon the results of a long-term field study of finch populations spanning several decades, combined with laboratory investigations of the molecular genetic basis of beak development.
Free and open to the public with a reception to follow.

About Darwin Day 2018
Darwin Day is Duquesne's annual international celebration of the life and work of Charles Darwin. The event emphasizes the importance of science education in today's world, and the impact that evolutionary biology has on many aspects of our lives.
