Darwin is sometimes called the Father of Modern Biology. His legendary trip to the Galapagos Islands on his ship the Beagle led him to his Theory of Natural selection. He published his ideas in the book On the Origin of Species, arguably one of the most influential science books of all time.
Celebrations are taking place all over the world. There are a couple of events in Milwaukee. The U of Arizona's event includes a Darwin Look Alike Contest (I thought sure they would get the U of A improv troup, The Charles Darwin Experience, to perform).
200 years later, our knowledge of biological evolution is getting to the point that we can apply it in fields such as food production and medicine. Biotech has the potential to revolutionize our lives in the next century.
Happy Birthday, Charles Darwin!
