Discuss the difference between homology and homoplasy.
(B) If you are interested in estimating evolutionary
relationships of organisms would you want to use homologous or
homoplasious traits? Explain your reasoning.
(C) Homoplasy often results from convergent evolution, where
similar traits evolve in distantly related organisms due to similar
environmental conditions. The image below shows this phenomenon at
the molecular level. Briefly discuss this image and how convergence
can lead to incorrect estimates of evolutionary relationships.
