The most recent installment of Tangled Bank, the mother of all biology blog carnivals, is up at Greg Laden. In this issue, Charles Darwin’s infamous nephew Derwin (perhaps that should be “un-famous”) travels forward into our time to learn about the current thinking in evolutionary biology, so that he can make a report to the natural philosophers of his own time.

Along with many dozen delightful posts from around the science blogosphere, Derwin’s missive also features our recent article on antagonistic pleiotropy in essential genes.
