Happy Darwin Day!

And if you happen to live in Broward County FLA, here's something you can do tomorrow to celebrate.

Happy Darwin Day 2009!

Today is the 200th anniversary of the birth of Charles Darwin. He is undoubtedly one of the most influential people in history. His Ideas are the cornerstone of modern biology. In fact, before Darwin, biology didn't really exist; or as Theodosius Dobzhansky famously said "Nothing in Biology Makes Sense Except in the Light of Evolution". His ideas about common descent and natural selection have even leaked into other branches of study such as linguistics and sociology. But his ideas didn't come from a vacuum; they weren't based on observation alone. He borrowed from thinkers in other fields.

Just how did he get there? For starters, Darwin began his studies with the intent of becoming a doctor. He found that he didn't have the stomach for surgery, so he switched to theology. A country vicar was the future that young Darwin saw for himself even up until he set sail on the Beagle. But even so, it was the study of nature that captivated him. As Janet Browne recounts, he was especially interested in a man whose ideas Darwin would eventually make obsolete.

In particular Darwin engaged with the theological views of Archdeacon William Paley, initially as part of his syllabus and then as independent reading. Darwin was expected to be able to answer questions in the final examinations on Paley's Evidences of Christianity and Moral Philosophy. After he graduated, he read the last of Paley's trilogy, Natural Theology (1802), with its argument that the adaptation of living beings to their surroundings was so perfect that it proved the existence of God. How could such a perfect design have come about, stated Paley, except from the careful hands of a designer? If a watch were accidentally found on a path, we would be entirely justified in thinking that it had been constructed by a skilled craftsman according to some design or plan. Such intricate mechanisms do not suddenly appear out of nothing, like magic. They are made by a maker. So, Paley argued, the world about us must be considered in the same way as the watch.

Darwin was also influenced by Malthus' An Essay on the Principle of Population which stated that populations grow exponentially until they no longer have the resources to maintain themselves, then they are subject to competition, poverty, and decline. Another great influence was Lyell's Principles of Geology which stated that land forms were not always as they as today, but rather formed slowly through natural processes (such as erosion, etc.). Ironically, Lyell specifically made an exception for living things which--of course--were not subject to change in the same way.


Charles Darwin circa 1860--about the time he published Origin of Species

Now contrary to popular opinion, Darwin didn't come up with his theory while observing all the different forms on the Galapagos. While he did note the variation from island to island with interest, it wasn't until he got back home and started to study his logs and samples and then really think about them deeply that his theory began to form. And once it formed, he took his time to get it right. Twenty years passed between his first documented mention of the idea and the publishing of Origin. The reasons for the delay are often debated among scholars, but what is for sure is that when he did publish, every i was dotted and every t was crossed. "He examined the minutiae of nature" notes biologist and writer Olivia Judson in today's New York Times "but worked on grand themes."

Could plants from the mainland colonize a newly formed island? If so, they would need a way to get there. Could they survive in the ocean? To find out, he immersed seeds in salt water for weeks, then planted them to see how many could sprout. He reported, for example, that “an asparagus plant with ripe berries floated for 23 days, when dried it floated for 85 days, and the seeds afterwards germinated.” The Atlantic current moved at 33 nautical miles a day; he figured that would take a seed more than 1,300 miles in 42 days. Yes, seeds could travel by sea.

Here are the first couple paragraphs from chapter IV of Origin, where he begins to explain his notion of natural selection.

Now let me finish my Darwin Day post with a shout out to my favoritest and adorablest nephew, Rafael Darwin.

Happy Belated Darwin Day!

Yesterday was Darwin Day. It marked the 198th anniversary of Charles Darwin's birth. The really big celebration will be in 2009, to celebrate the bicentennial. Among the events we should expect on that day is the culmination of the Beagle Project.

Welcome to the Beagle Project: we aim to provide the most compelling events of Charles Darwin's 2009 anniversary by building a sailing replica of HMS Beagle and sailing in Darwin's wake. The build and Beagle's arrival in the Galapagos in 2009 will be two of the most striking, iconic media events of the 2009 celebrations, aimed at firing the scientific imaginations of a new generation and celebrating the life and work of Charles Darwin, one of the greatest biologists ever.

I encourage everyone who hasn't done so already, to check out their website and donate some money to an incredibly worthy project.

But why did I wait until today to post this? Quite simply, I consider November 22nd to be the true Darwin Day. That was the day (in 1859) when The Origin of Species went on sale; that was the day that changed the world. I've always thought that celebrating the birthdays of important people missed the point. It makes sense to celebrate one's own birthday--or the birthday of one's child or loved one--that date has personal significance. But when you're talking about an important historical figure, their birth is really insignificant. I mean, what really happened on the day that George Washington, or Caesar Augustus, or Martin Luther King Jr. was born? Another baby was delivered. Whoop-dee-doo! It wasn't until later that these people would do what made them "go down in history."

If you're familiar with my blog, then you've probably already smelled the BS. Fact is, I was travelling much of the day yesterday, and when I got home it was late and I was tired and just not in the mood to write the post I had planned. I do however stand by everything I said about important people's birthdays--just not enough to eschew celebrations.

On a final note, I'd also like to encourage evryone to become a Friend of Charles Darwin. That way you can put FCD after your name--just like me.
