Life's Edge: The Search for What It Means to Be Alive by Carl Zimmer

4.0

"Life's Edge" is a fascinating overview of biological concepts of life that not only stretch our own imaginations, but call into question what we thought we knew. Or at least for me it did. The brief histories and biographies are interesting snippets, particularly since I've heard of few of these figures and organisms.
