Question

QUESTION 14 Below is a cartoon depicting various geological events, starting with one large island (panel 1) and ending with four smaller islands sequentially splitting off from each other (panels 2 to 5). Initially, there was only Species A inhabiting on the big island. However, as time went on, more species evolved on these smaller islands, such that at the current time (panel 5), there are five species. Their phylogenetic relationships are shown on the last panel. Please answer questions 14, 15, and 16. Question 14: Based on the history depicted, most of these speciation events are likely mediated through 1 species evolves into B evolves into evolves into C 5 B 2 @ @ @ @ 0 A. the sympatric speciation process B.the reinforcement process C.the dispersal and colonization process D. the vicariance process E. the hybridization process

Answer 1

ANSWER 14-Sympatric speciation process.

ANSWER15-Allopatric speciation from species A to E

ANSWER 16-We should expect to observe complete reproductive isolation manifested as prezygotic isolation.
