Question 2

1 mark

Courtship behaviour is often essential for successful mating in many animal species. Which of the following is not a primary role of courtship behaviour in species recognition?

Question 3

A researcher is comparing two species of primates to determine their phylogenetic proximity. Which of the following comparative methods would provide the most precise quantitative evidence for their evolutionary divergence, considering the limitations of degenerate codes and non-coding regions?

Question 4

Which of the following describes the most accurate hierarchy of taxonomic ranks according to the phylogenetic classification system?

Question 5

1 mark

Which of the following describes the correct order of taxonomic ranks in a phylogenetic hierarchy, moving from the most inclusive group to the least inclusive?

Question 8

5 marks

In the context of species recognition, describe how specific courtship behaviours function as a selective mechanism to prevent the waste of metabolic energy and gametes between closely related species living in the same habitat.

Question 9

6 marks

Two different species of birds live in the same forest. Biologists observed their courtship behaviors to determine if they belong to the same species.

a) Define the term species according to the biological species concept. (1 point)
b) Explain the role of courtship behavior in species recognition and why this is important for the survival of the species. (3 points)
c) Recent advances in genome sequencing have allowed scientists to clarify the evolutionary relationships between these birds. Describe how comparing the base sequence of DNA can be used to determine how closely related two species are. (2 points)
