  • Natural Selection
    A process where certain inherited traits become more common in a population due to increased survival and reproduction.
  • Variation
    Differences in traits among individuals within a population, often inherited from parents.
  • Adaptation
    A trait that increases an organism's chance of survival and reproduction in a specific environment.
  • Population
    A group of individuals of the same species living in the same area, subject to evolutionary changes.
  • Fitness
    The relative likelihood of an organism passing its genes to the next generation compared to others.
  • Overproduction
    The tendency of species to produce more offspring than the environment can support, leading to competition.
  • Genetic Variation
    Heritable differences in DNA among individuals, forming the basis for selection.
  • Competition
    The struggle among members of a species for limited resources, influencing which traits are passed on.
  • Trait Frequency
    The proportion of individuals in a population that possess a specific characteristic.
  • Camouflage
    A physical characteristic that allows organisms to blend into their environment, reducing predation risk.
  • Mortality
    The rate at which individuals in a population die, often influenced by environmental factors and traits.
  • Evolution
    A change in the genetic makeup of a population over generations, often driven by selection.
  • Environment
    The external conditions and factors that influence which traits are advantageous in a population.
  • Offspring
    The descendants produced by organisms, inheriting traits from their parents.
  • Adaptations
    Accumulated traits in a population that enhance survival and reproductive success in a given environment.
