Scientists have sequenced the genome of the medium ground finch, one of the Galápagos finches that inspired Charles Darwin to formulate his theory of evolution by natural selection. Dr. Peter Grant has studied these finches in the wild for nearly 40 years, observing and documenting evolution in real time. He discusses his work, what rapid genome sequencing will mean for the future of evolutionary biology, and why there will always be a place in science for careful field observations.
