Title Page, Copyright, Dedication
Science has always been my favorite form of whodunit, especially when the scientist discovers a tantalizing mystery and solves it with clever experiments or observations. Regrettably, some very tantalizing mysteries remain on the back shelf of science, never having made it to the bestseller list. Death is one such mystery. We all know that death, like reproduction and metabolism, is a...
Introduction: Death the Mystery
Human beings are near-perfect animals. Of course, we might be improved with a few minor adjustments—strengthening the back for lifting and bearing in an upright posture, broadening hips for ease and safety of childbirth1—but, with one major exception, we are exquisitely adapted to our way of life: to survival and reproduction in our terrestrial habitat and agricultural-mechanized-...
Part I. How Biology Makes Sense of Death
In the past, death posed a conundrum for biologists: death as such did not seem to perform a function in life, yet death seemed a part of life, since only living things died. Indeed, death did not seem to be one of life’s qualities, even though, with few exceptions, it was the end of life. Likewise, death seemed incapable of evolving, since it did not contribute to the fitness of the individual, ...
Chapter 1. Evolution: Death’s Unifying Principle
All living things have their own ways of dying or not. I describe these ways in the appendix, but The Evolution of Death is primarily concerned with death in Homo sapiens—our death. If we are ever to understand death, it will be because we see it as part of life—as evolving. Science got it wrong several times in the past, but the consequences of death’s resuscitation, its reinstallation ...
Chapter 2. Charting Death’s Evolution and Life’s Extension
Death’s evolution? What irony! How could death evolve when it has no apparent benefit for the survival or reproduction of individuals? How could the manufacture of corpses, aka death, evolve? What would possibly constitute evidence for death’s evolution? Intuitively, one might suppose that the evolution of death would make life ...
Chapter 3. Rethinking Lifecycles and Arrows
Even were one to concede that death is part of life, one would want to see how death is integrated into life’s other features before accepting death as evolving. Well, let us not mince words: one must reorient oneself entirely to life in order to integrate death. I cannot pretend that biologists share a single view of death’s integration ...
Chapter 4. Keeping Life Afloat
The great irony exposed in chapter 3 is that death contributes to life principally by providing the sink for life’s waste—corpses. Chapter 4 examines some of death’s other effects on life, effects that turn out to be salubrious rather than corrosive as might have been expected. The chapter begins by answering the question, why is life so profligate? ...
Chapter 5. Putting Cells in the Picture
Many pieces of death’s puzzle have now fallen into place: from dissipative structures far from thermodynamic equilibrium at the edges of chaos to odds making and supply-sided economics.1 But the puzzle is still incomplete. Since the ninteenth century, cells have been required to make sense of life. Chapter 5 puts cells into the picture of death....
Chapter 6. Neoteny and Longevity
The bagpipe model of life extension illustrated in chapter 2 suggests that we are living longer because our juvenile stage of development is percolating into our adult stages. Chapter 6 examines this suggestion, beginning with a discussion of the phenomenon of juvenilization known in the evolutionary literature as neoteny, from the Greek meaning stretching (“extending” or “holding ...
In the preface, you may remember, I suggested that science is like a whodunit, a detective story where a crime is uncovered and a mystery is solved. As things turned out, the evolution of death is not the crime I thought it was. Rather than a corrosive force shortening life, death’s evolution turned out to be a salubrious force lengthening life! ...
