I'm kind of reading three books:
"Lucy's Child" by Donald Johanson and James Shreeve - It'st he sequel to Lucy: The Beginnings of Humankind. It's about paleoanthropology.
"The Blank Slate" by Steven Pinker - I just finished "How the Mind Works" and was enamored so I picked this up
"Under the Banner of Heaven: A History of Violent Faith" by Jon Krakauer - It's about freaky polygamist Mormons.
