How do scientists think that the common rosefinch came from asia to hawaii

Scientist think that about 5.8 million ago an errant group rosefinches migratory was caught up in the winds of huge storm. Maybe they were looking for 'greener pastures’. Thousands of the birds in that flock could have died during the transport, but hundreds could have survived. They flies at least 7000 miles to the Hawaii archipelago across the ocean. The large distance between islands increases the potential for diversification

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
