Question

more than 20 species of hawaiian honeycreepers are descended from a goldfinch - like ancestor that arrived on one of the islands about 5 million years ago from asia or north america. the birds of the various species are similar in body size and shape, but differ in color and beak shape. how could so many species have evolved from a single ancestral species? fill in the missing words. natural selection founder effect geographically isolated species evolution the ancestral finch founded a new population on one of the hawaiian islands. due to the, allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch - like ancestors. the process of resulted in adaptation and of the island population into a new over time. some of the birds crossed to some of the other islands where they were and evolved into more species occupying different niches

Explanation:

Answer:

The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect, allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch - like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.
