Why organisms age and why sexual reproduction exists are major unsolved problems in biology. This book provides an integrated explanation of aging and sex based on current knowledge of DNA damage and repair.

Key Features

  • Discusses the universality of the problem of DNA damage
  • Describes aging as a consequence of accumulated DNA damage
  • Considers meiosis as an adaptation for DNA repair
  • Discusses mating in eukaryotes as an adaptation for masking mutation


Molecular biologists, geneticists, biochemists, and cell biologists researching aging, DNA repair, or sexual reproduction, as well as evolutionary biologists and gerontologists
