Which form of speciation is most rapid A. sympatric speciation via character displacement B. allopatric speciation on the island archipelagos C. sympatric speciation via autopolyploidy D. allopa?

B. Allopactric speciation on island archipelagos. As the organisms move from island to island rapid speciation is observed because of variations in resource acquisition more than just variation in environment. Amplified radiation is observed. Example is finches on the Galapagos Islands. Hawaii also gives this example.

Why did john white leave the Roanoke colony?

John White left the Roanoke colony in 1587 to return to England for more supplies. He was delayed in his return due to the Anglo-Spanish War, which prevented him from coming back to the colony until 1590. By the time he returned, the entire colony had disappeared, with no trace of the settlers to be found.


Why did most of the settlers of Roanoke Island return to England?

If you mean the 1587 colony - popularly known as "the lost colony" - the settlers did not return to England. Governor John White left Roanoke Island in August of 1587 and returned to England to secure more supplies. The remainder of the settlers stayed on Roanoke Island. When John White came back to the island in 1590 he found no trace of his colony. Their fate is unknown. There are several theories as to what might have happened to them; some may have moved south to live with the friendly natives and some may have tried to sail back to England. There is some evidence to support the theory that some moved north towards the Chesapeake. The two earlier voyages (1584 and 1585) were largely reconnaissance voyages to scout suitable locations for military bastions. Neither of these voyages included women and children. The 1585 members left Roanoke Island with Sir Francis Drake, leaving 15 men there to take care of the fort. Bad leadership, blunders and cruelty towards the natives, and lack of supplies were largely responsible for the failure of this attempt at colonization and when Sir Francis Drake arrived at Roanoke Island the men were only too glad to return to England.


What is Roanoke Colony known for?

The 1587 colony is known as the lost colony. A group of 117 men, women and boys (no girls) attempted to found a colony on Roanoke Island, in what is now North Carolina, in 1587. Three years later Governor John White, who had returned to England in August of 1587 to secure more supplies, arrived on Roanoke Island but there was no trace of his colonists. There were two clues "CRO" and "CROATOAN" carved on a palisade and a tree, which may have given some indication where at least some of the people had gone, but there was no definitive information.
