Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	All the green larvae develop yellow stripes before metamorphosis.
B	All the yellow larvae and none of the green larvae are eaten by birds.
C	The percentage of green larvae in the population is much greater than the percentage of yellow larvae.
D	The percentages of green larvae and yellow larvae in the population remain equal for many generations.

Explanation:

Detailed explanation-1: -Scientists often compare fossils of extinct organisms with living organisms to help determine evolutionary relationships.

Detailed explanation-2: -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-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.
