Central Tenets of Evolution Theory

When scientists announced last month they had determined the exact order of all 3 billion bits of genetic code that go into making a chimpanzee, it was no surprise that the sequence was more than 96 percent identical to the human genome. Charles Darwin had deduced more than a century ago that chimps were among humans’ closest cousins.
But decoding chimpanzees’ DNA allowed scientists to do more than just refine their estimates of how similar humans and chimps are. It let them put the very theory of evolution to some tough new tests.
If Darwin was right, for example, then scientists should be able to perform a neat trick. Using a mathematical formula that emerges from evolutionary theory, they should be able to predict the number of harmful mutations in chimpanzee DNA by knowing the number of mutations in a different species’ DNA and the two animals’ population sizes.
“That’s a very specific prediction,” said Eric Lander, a geneticist at the Broad Institute of MIT and Harvard in Cambridge, Mass., and a leader in the chimp project.
Sure enough, when Lander and his colleagues tallied the harmful mutations in the chimp genome, the number fit perfectly into the range that evolutionary theory had predicted.

About This Site

As a guy who occasionally curates art shows and wrangles artists together, I often have to edit and post artist bios, profile pictures, and artwork images. This can be a problem, since many artists and writers aren’t used to selling themselves. Artists rarely know how to present their art for display in a brochure, and writers aren’t used to writing about themselves.

Writers often treat the bio like it’s an interview or something. Maybe like they’re having a conversation with you, the reader. While it may work sometimes, the most common way to write a bio is to write in the 3rd person.

I’m like those writers, and I’m talking to you directly, unlike the common way to do a bio. You should see my About page. It makes sense to me, since this is a bit which describes my blog’s website. When I get famous enough that I don’t have time to talk to you, I’ll have an intern write everything in 3rd person. Until then, you get to talk to me.

Like blogs of old, this one is a personal document of the comings and goings of me. Articles I’ve written, links I’ve posted, videos I liked, etc. Here, a first-person perspective is the way to go, at least for now. So, this is my site. I’m D. H. McKee, a sometimes artist, sometimes writer. Mostly just a guy on the internet.
