which significant change can occur to a small population as a result of genetic drift?

Large changes in allele frequencies can occur in a short time.
New individuals add their genes to the gene pool.

a bird’s wing, a dolphin’s fin, and a cat’s paw are homologous structures. what about these structures supports the theory of evolution?
