Both Charles Darwin and Alfred Russel Wallace acknowledged the influence of the economist Thomas Malthus in the development of their ideas about natural selection. Specifically, Malthus's ideas about geometric population growth implied that: only the largest and strongest individuals would survive survival of the fittest resources in every generation would be limited organisms should have as many offspring as possible organisms should have a few, very fit offspring who can compete for scarce resources
