Answer:
Explanation:
Islands are natural laboratories where evolution can be studied. The fact that islands are isolated from the mainland by the sea makes that island biota present spectacular adaptations, sometimes originating giant or dwarf species in comparison with their mainland relatives.
Examples.
-Islands can have a volcanic origin, involving the emergence of virgin lands that will be colonized involving new adaptations to the new conditions.
-Islands can also have a continental origin, involving the separation of the mainland by tectonic processes and isolation of fauna and flora before connected.
-oceanic islands, present no predators and this triggers the appearance of very curious adaptations. One of the most surprising processes is gigantism in animals or woodiness acquisition in plants.
Woodiness acquisition This is as a result of the absence of herbivores and competitors in sterile islands, which would allow developing a greater height willing to reach sunlight.
