Explanation: 

Detailed explanation-1: -The essence of Darwin’s theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance.

Detailed explanation-2: -Scientists often compare fossils of extinct organisms with living organisms to help determine evolutionary relationships.

Detailed explanation-3: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related.

Detailed explanation-4: -Which of the following describes how a large mouse population with high genetic diversity will most likely be affected by a sudden, significant environmental change? Only those individuals best adapted to the new environment will survive and reproduce, leading to a decrease in genetic diversity.
