Franklin M. Harold's On Life reveals what science can tell us about
the living world. All creatures, from bacteria and redwoods to
garden snails and humans, belong to a single biochemical family. We
all operate by the same principles and are all made up of cells,
either one or many. We flaunt capacities that far exceed those of
inanimate matter, yet we stand squarely within the material world.
So what is life, anyway? How do living things function, and how did
they come into existence? Questions like these have baffled
philosophers and scientists since antiquity, but over the past
half-century answers have begun to emerge. Offering an inside look,
Franklin M. Harold makes life accessible to readers interested in
the biological big picture. The book traces how living things
operate, focusing on the interplay of biology with physics and
chemistry. He asserts that biology stands apart from the physical
sciences because life revolves around organization- that is,
purposeful order. On Life aims to make life intelligible by giving
readers an understanding of the biological landscape; it sketches
the principles as biologists presently understand them and
highlights major unresolved issues. What emerges is a biology
bracketed by two stubborn mysteries: the nature of the mind and the
origin of life. This portrait of biology is comprehensible but
inescapably complex, internally consistent, and buttressed by a
wealth of factual knowledge.
The origin of cells remains one of the most fundamental problems in
biology, one that over the past two decades has spawned a large
body of research and debate. With "In Search of Cell History,"
Franklin M. Harold offers a comprehensive, impartial take on that
research and the controversies that keep the field in turmoil.
Written in accessible language and complemented by a glossary for
easy reference, this book investigates the full scope of cellular
history. Assuming only a basic knowledge of cell biology, Harold
examines such pivotal subjects as the relationship between cells
and genes; the central role of bioenergetics in the origin of life;
the status of the universal tree of life with its three stems and
viral outliers; and the controversies surrounding the Last
Universal Common Ancestor. He also delves deeply into the evolution
of cellular organization, the origin of complex cells, and the
incorporation of symbiotic organelles, and considers the fossil
evidence for the earliest life on earth. "In Search of Cell History
"shows us just how far we have come in understanding cell
evolution--and the evolution of life in general--and how far we
still have to go.
