Across
  1. 2. similarity due to convergent evolution; similar environmental pressures or natural selection
  2. 3. a population of individuals capable of naturally interbreeding and producing fertile offspring
  3. 4. speciation that occurs in populations that coexist in the same area
  4. 6. speciation that occurs as a result of geographic isolation
  5. 8. accumulated effect of microevolution over time; evolution above the species level
  6. 9. extinction that occurs at lower rates during times other than mass extinctions
  7. 10. evolution that occurs when species have different ancestors but develop similar features due to similar selective pressures
  8. 11. offspring produced through mating of two different species
  9. 13. the evolutionary history of organisms
  10. 14. evolution that occurs when two species evolve differently from a common ancestor
  11. 15. change in allele frequencies over one or a few generations
Down
  1. 1. a small number of species diversifies into a much larger number of species during a brief period of time
  2. 5. the complete loss of all individuals in a species population
  3. 7. similarity due to shared ancestry
  4. 8. extinctions where a large number of species become extinct over a short period of time due to sudden environmental changes
  5. 12. one species splits into two distinct species
