Sketchbook

Today's sketchbook:

Blue plate, with fork

The kids had a friend over this morning, so we had a little crayon session. Here are the remains of Gretchen's coffee cake. I haven't really tried to work with crayons forever -- it's easy to forget how hard they are to control.

I generally save really poor-quality jpegs for the blog. With the pencil or ink drawings it doesn't make much difference, and I don't mind if they're a little ugly -- I'm paying for the bandwidth, after all. But the crayon scan really loses vibrancy in the jpeg, and I haven't figured out a way to compress it without losing that brightness.

OK, what am I complaining about? It's crayon!

I'm staying independent and advertising-free. Independence means I can have things like the 12,000-reference live online bibliography. No advertising means I can reach more teachers, students and international readers. But it takes some money to run the place. I've been supported over the years by small donations from a few generous readers. Thank you for your support!

If you access Amazon through one of my links, Amazon will give 6% of every purchase (and more for certain items or rentals) to the site. It doesn't cost you any more, but it really helps out here. Some of my most generous supporters are companies and departments who use these links with their purchasing cards. The price is the same, the difference is that a small percentage supports this site. Either this link, the search box below, or any other Amazon links on the site will work.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
