Consider two phylogenetic tree scenarios representing discordance between gene trees and species trees: Scenario A shows evolutionary patterns arising from interspecific gene flow, while Scenario B shows discordance due to the persistence of ancestral polymorphisms across speciation events. Select the option that correctly identifies these two evolutionary processes.

Match List I with List II with respect to chronology of evolution of life forms: List I A. About 65 mya B. About 500 mya C. About 350 mya D. About 320 mya List II I. Jawless fish probably evolved II. The dinosaurs suddenly disappeared from the earth III. Seaweeds and few plants probably existed IV. Invertebrates were formed and became active Choose the correct answer from the options given below:

Which of the following is NOT an example of convergent evolution?
