Question

Many years ago, tree-climbing, leaf-eating iguanas migrated from the mainland of South America to the Galapagos

Islands. The only food available was algae that grew on the rocks in the water near shore. Scientists believe that
the iguanas that survived were those that could swim well, cling to slippery rocks with large claws, and eat a new
diet. What type of adaptation is this?
A. Crossbreeding
B. Natural selection
C. Selective breeding
D. Occasional mutation

Answer 1

Option: B

Step-by-step explanation:

The type of adaptation described in the scenario is B. Natural selection. Natural selection refers to the process by which individuals with favorable traits or adaptations are more likely to survive and reproduce, leading to the passing on of those traits to future generations. In this case, the iguanas that were able to swim well, cling to slippery rocks, and adapt to a new diet of algae were the ones that survived in the new environment of the Galapagos Islands. Over time, these traits became more common in the iguana population as they were advantageous for their survival in that particular habitat.
