  • Camouflage and mimicry are examples of
    Adaptations
  • The more genetic variation a population has, the more likely it is for the population to _______________.
    Evolve
  • Give an example of an adaptation
    (open - up to teachers discretion)
  • Traits that allow an organism to survive and reproduce in their environment
    Adaptations
  • By having these (insert term we learned), organisms can have increased fitness
    Adaptations
  • Natural selection works directly on genotype/phenotype (choose 1)
    Phenotype - the physical traits
  • True/False - Evolution by natural selection is a scientific theory.
    True! It's been tested with experiment many times from multiple lines of inquiry and accepted
  • Survival of the Fittest was proposed by this English naturalist
    Charles Darwin
  • These are the remains of organisms that lived long ago and can be connected to organisms that live in the modern time
    Fossils
  • Phrase that goes with "the fittest don't die out and therefore reproduce and pass on their genes"
    Survival of the Fittest
  • Domesticated dogs are an example of
    Artificial Selection (selective breeding)
  • The term for a group of similar organisms that can reproduce and make fertile offspring
    Species
  • Large, flightless birds like the Ostrich and Emu evolved similarly due to similar _____________________.
    Environments
  • The change in a population over time is called
    Evolution
  • True/False - Organisms decide to change over time
    False! The environment shapes organisms
  • Give an example of an artificially selected organism
    (open - up to teachers discretion, answers vary)
  • True/False - Individuals evolve over time
    False! Populations evolve, not individuals
  • The ability of an organism to survive and reproduce in their environment
    Fitness
  • The Glyptodont is an example of
    a fossil
  • True/False - A trait is only useful to a population if it can be passed on to future generations
    TRUE
  • When an animal breeder or farmer chooses the best traits to produce a better livestock they are using the process of
    Artificial Selection
  • The differences among a species, like different shaped turtle shells, are called
    Variations
  • True/False - All traits are adaptations.
    False - some traits are not adaptations; Ex: the red color of blood
  • The name of the process where organisms that are better adapted to their environment tend to survive and produce more offspring.
    Natural Selection
  • The Galapagos tortoises showed that species vary _______________ .
