Time to crank up the blog and welcome students from my Contemporary Issues in Science class.
Over the summer I read (most of) An Ancestor's Tale. What an amazing book. Although Dawkin's outspoken atheism can be off-putting, his command of zoology, genetics, and evolutionary theory deserve acclaim.
In other news, new fossils push back the origin of animal life even further - 650 million years. As I've said before, advances in technology always seem to push the dates further back into our planet's history. The dates rarely come forward. The antiquity of "life" continues to astound.
