• What defines a species?

  A group of similar organisms that can breed
• Why must species reproduce?

  To pass on advantageous alleles for survival
• What are courtship rituals?

  • Unique sequence of actions for each species
  • Helps animals identify members of their species

• What is the focus of Kores' study?

  Study of courtship rituals
• What does a similar courtship sequence indicate about species?

  They are more closely related
• How does the similarity of courtship sequences relate to species relationships?

  More similarity indicates closer relationships
• How are courtship rituals are genetically determined?


  The more similar a species sequence is the more similar ther DNA base sequence is.
