Across
  1. 4. a type of natural selection that favors intermediate (average) phenotypes rather than extreme variations, reducing phenotypic variation in a given population
  2. 6. a type of genetic drift occurring when a population size is severely reduced for at least one generation by a random disaster such as a fire, flood, famine, or human impact/influence
  3. 8. an evolutionary model displaying a pattern of long periods of stasis (little or no change) in a species, interrupted ("punctuated") by brief, rapid bursts of significant change and speciation/population diversity
  4. 9. anatomical features, behaviors, or molecules in an organism that have lost all or most of their original function(s) through evolution
Down
  1. 1. a diagram representing the evolutionary relationships and descent among species, often based on genetic or anatomical features, that shows common ancestry
  2. 2. field focused on classifying organisms and determining their evolutionary relationships
  3. 3. technique used in biology and geology to determine the chronological order (age) of fossils or rock layers
  4. 5. a branch of biology focused on identifying, naming, and classifying organisms into hierarchical groups (taxa) based on shared traits and evolutionary relationships
  5. 7. a species or group known to have diverged before the lineage of all other organisms being studied (the ingroup)
  6. 10. a species or disease that is native to and consistently found in a specific, "restricted" geographical area.
