Evolution by natural selection
  1. Overproduction
    1. Capacity to produce more offsprings than environment can sustain
    2. Stability of population sizes
      1. Remain stable regardless of individuals' capability to overproduce
      2. Limited resources
        1. environment=resources limited
          1. Competition between individuals for resources, successful indiv. live
        2. Individual variability
          1. No two individuals are identical
          2. Heritability of individual variability
            1. Parents pass on particular traits to their offsprings, they pass on their individual variability
            2. Important points about evolutions
              1. Individuals do not evolve: population does
                1. Only heritable traits can be passed on
                  1. Traits success depends on environment
