Presentation Transcript

  1. SPECIES AND SPECIATION

  2. What is a species? • Morphological Species Concept • Phylogenetic Species Concept • Biological Species Concept

  3. Morphological Species Concept • Use physical similarities to classify species

  4. Phylogenetic Species Concept • Use shared, unique genetic history to classify species

  5. Biological Species Concept • Use ability to mate and produce offspring that can also mate and reproduce to classify species

  6. How do species form? • When a group of individuals remains isolated from the rest of its species long enough to evolve different traits • How can some members of a species become separated from the main group?

  7. Geographical Isolation • Physical barrier

  8. Temporal Isolation • Reproduce at different times

  9. Habitat/Spatial Isolation • Occupy different habitats in the same area

  10. Behavioral Isolation • Different courtship displays

  11. Resource Isolation • Use different resources in the same area

  12. Mechanical Isolation • Physically incompatible

  13. Activity • Draw a diagram of your method of speciation • Write a description of what is happening
