The Galápagos tortoises share a common ancestor, but have necks of different lengths to best reach the food they need in their environment.
A
Convergent
B
Divergent
C
Coevolution
D
None of the above
Explanation: 

Detailed explanation-1: -Over time, Darwin began to wonder if species from South America had reached the Galapagos and then changed as they adapted to new environments. This idea-that species could change over time-eventually led to Darwin’s theory of evolution by natural selection.

Detailed explanation-2: -For example, a population of giant tortoises found in the Galapagos Archipelago was observed by Darwin to have longer necks than those that lived on other islands with dry lowlands. These tortoises were “selected” because they could reach more leaves and access more food than those with short necks.

Detailed explanation-3: -The Galapagos finches evolved through natural selection from a common ancestor into a wide variety of different looking species with different kinds of beaks.
