    as mountains or rivers
  4. 4Temporal Isolationoccurs when populations reproduce at different times
  5. 5Geographical Isolation in Galapagos FinchesThe population of finches on separate islands are geographically isolated from one another by the ocean
  6. 6Behavioral Isolatation in Galapagos FinchesBig-beaked finches that prefer to mate with other big-beaked finches are behaviorally isolated from small-beaked birds living on the same island.
  7. 7Speciation in Galapagos FinchesThe finches probably flew from mainland to 2 islands. There might have been different food on the second island, such as seeds, which caused the big beaks to be favored. Over time, natural selection happened and caused a formation of a new species.
  8. 8Reproductive Isolationoccurs when a population splits into two groups and the two populations no longer interbreed
  9. 9Biological Species ConceptReproduction is possible, offspring will survive and reproduce
