At their best, blogs tell you something you didn’t know, in the same way you learn something from an interesting person you meet at a party. John Wilkins, a philosopher of science, has just such a post up at Evolving Thoughts. He addresses the strangely enduring meme, “If we evolved from monkeys, then why are there still monkeys?”

While the entire post is enlightening, I was especially taken by a detail. In the mid-1700s Carl Linnaeus established the first large-scale system for classifying species. Linnaeus once declared, “There are as many species as the Infinite Being produced diverse forms in the beginning.” I was aware that his religious views did not stop him from putting humans (Homo sapiens) in the primate order.

Here are a fresh batch of reviews for Microcosm: E. coli and the New Science of Life

Cleveland Plain-Dealer: “For readers who enjoy a seat at the revolution and a chance to ponder the ‘supple little bugs’ at the dawn of life, Microcosm’ is a bracing read. This timely book deserves shelf space near Lewis Thomas’ classic, ‘Lives of a Cell.'”

A wonderful review of Microcosm just came out in the Times of London. It’s particularly gratifying to see it written by Oliver Morton, a science writer gifted with grace and style…

[Zimmer] “comes up with turns of phrase and images that are deep delights. The ways in which the structure of the cell depends on the tempo of different molecular processes give it a ‘geography of rhythms’; the building of a flagellum, which takes longer than the bacterium’s replication, is like building a medieval cathedral, in that ‘a new microbe inherits a partially built tail and passes it on, still unfinished, to its descendants.

Can we make a picture of history? Charles Darwin recognized that all the different species on Earth share a common ancestry, having branched apart over millions of years. He pictured the history of life as a tree, as he sketched here in one of his notebooks. He later published a more formal illustration of the tree of life–or at least the branching of evolution–in the Origin of Species. Later scientists put actual names to the branches. They proposed that birds and crocodiles share a close common ancestry, for example, based on traits they share in common in their skeleton and skin. Later studies–including comparisons of DNA–supported many of those relationships. Today scientists are comparing entire genomes in order to illuminate some of the murkier nooks in the tree.

A couple weeks ago I spoke to a great crowd as part of the Zocalo lecture series in Los Angeles. The subject was my new book, Microcosm: E. coli and the New Science of Life. You can listen to the podcast here, [whoops–go to this page and look for my mug.) and the talk will be airing several times starting today on LA City Channel 36. I think that you will also be able to watch it on their web site live. Here is the schedule (all times PST):
