DarkSyd has done it again! After the gorgeous post on evolution of cats , he has now penned another one - on evolution of whales! Dig through the archives for his older stuff on human evolution, too.
Afarensis has started a great new project: a group blog about evolution that targets schoolchildren (primarily middle and high school). It is called Transitions and already has some excellent articles, e.g., this one on the evolution of elephants, one on evolution of opossums and the most recent one about misunderstanding evolution. If you think you can contribute, there is contact information at the site.
