  • Natural Selection
    Process where environmental pressures favor certain traits, leading to increased reproduction of individuals with those traits.
  • Artificial Selection
    Selective breeding by humans to enhance desired traits in organisms, such as crops, pets, or livestock.
  • Variation
    Genetic differences among individuals in a population, providing the raw material for evolutionary change.
  • Fitness
    Relative ability of an organism to survive and reproduce in a specific environment, influencing trait prevalence.
  • Selection Pressure
    Environmental factor, such as predation or antibiotics, that influences which traits are advantageous.
  • Antibiotic Resistance
    Ability of bacteria to survive and multiply despite the presence of drugs designed to kill them.
  • MRSA
    A strain of Staphylococcus aureus that has evolved resistance to methicillin and related antibiotics.
  • Adaptive Evolution
    Change in a population's traits over time that enhances survival and reproduction in a particular environment.
  • Camouflage
    Trait that allows organisms to blend into their environment, reducing detection by predators.
  • Rock Pocket Mouse
    Desert rodent known for coat color variation, providing a real-time example of adaptation to different substrates.
  • Gene
    Unit of heredity that influences traits, such as coat color, and can be tracked as populations evolve.
  • Population
    Group of individuals of the same species living in a specific area, subject to evolutionary processes.
  • Trait
    Observable characteristic, such as beak size or fur color, that can be influenced by genetic and environmental factors.
  • Pigeon Fancier
    Individual who breeds pigeons for specific characteristics, illustrating artificial selection.
  • Substrate
    Surface or material, like volcanic rock or desert sand, that influences which traits are advantageous for survival.
