Evo in the news: Another perspective on cancer

Author/Source: UC Museum of Paleontology
Overview:This news brief, from October of 2007, describes the evolutionary underpinnings of cancer. Recognizing cancer as a form of cellular evolution helps explain why a cure remains elusive and points the way toward new treatments.
Concepts:This lesson covers the following concepts:
  • Evolution results from selection acting upon genetic variation within a population.
  • Inherited characteristics affect the likelihood of an organism's survival and reproduction.
  • Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.
  • Natural selection acts on individuals and populations in a nonrandom way.
  • Populations evolve.
  • The proportion of individuals with advantageous characteristics may increase due to their increased likelihood of surviving and reproducing.
  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
