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. 1 2 evelves into species 3 4 velves ite evolres nto A 5. 2 D] A Based on the history depicted, MOST of these speciation events are likely mediated through? the sympatric speciation process the reinforcement process the dispersal and colonization process the vicariance process the hybridization process

-nstion 18)If Species A and Species E were to encounter each other, which of the following statements is correct? We should expect to observe complete reproductive isolation manifested as prezygotic isolation. If hybrids were formed between these two species and the hybrid offspring has a lower fitness than either parental species, then we would expect the evolution of reinforcement. Since A is the ancestral species and E the evolved species, therefore, we expect the introduced Species A on Island 4 be out-competed by Species E. Species A and Species E will form hybrids together, thus removing genetic isolation between these two species.
