It is widely accepted that the world around us is changing, and as a result the organisms that exist adapt with that change or are resigned to the fossil record. Evolution, it’s a fact of life… or is it? UCLA paleobiologist J. William Schopf, and colleagues, have discovered an organism that has remained relatively unchanged over a 2.3 billion year period. Meh, who needs evolution? These bacteria were discovered in the muddy sediments of the deep sea and represent the greatest lack of evolution ever seen!

Because we can look into these organisms and learn something about our own deep past, we think of them not as modern descendants, but as living fossils, relics of a primeval state.
Once more, three months have passed in our ongoing series, 365 days of Darwin. For new readers, our favorite stuffed Charles Darwin doll is spending a year traveling around the world and updating us all on his adventures, daily. The last three months, Charlie has traveled farther than ever before. You can checkup on his first sixth months here: 365 days of Darwin: The first 3 months and here: 365 days of Darwin: The second 3 months. Check below the fold for a summary of his most recent 3 months. The adventure continues!
Charlie has had quite and adventure these first few months. His journey began November 24, 2009 – the 150th anniversary of the publication of the Origin – by congratulating Kevin Zelnio on his outstanding Great Darwin Beard Challenge win:
