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
*evolution
resulted in adaptation and
*natural selection
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.
