  1. Fishy Frequencies

  2. Vocabulary: • Macroevolution: evolution occurring over geologic time that results in the formation of new taxonomic groups.

  3. Microevolution: • Evolution caused by small variations that can lead to a new subspecies

  4. Mortality: • The number of individuals that dies each year within a population.

  5. Birthrate: • The number of individuals born each year into a population

  6. Frequency • How often a variation occurs in a population (a percentage)
