150 years ago today, Darwin published "The Origin of Species." It was one of those seminal moments in science where an individual managed to put into words how we might understand the way the world works. I don't think Darwin got everything "right," nor was he working in a vacuum. His insights were built on observations both of his own and others. But he did eloquently illustrate the concepts of natural selection and how it might work and explain the diversity of life we see today.
It's too bad we have so many people (some of them well-intentioned, some of them much less so) opposed to the concepts that have been borne of this work.
