Answer 2

## Step 1The theory of evolution primarily focuses on the change in populations of species over time. This is because it explains how species have evolved and adapted over time to survive in their environment.## Step 2The theory of evolution suggests that all living species have descended from common ancestors. This is because all living organisms share some common characteristics, which suggests a common ancestry.## Step 3Natural selection is considered the primary mechanism of evolution. This is because it explains how species adapt to their environment and how beneficial traits are passed on to future generations.## Step 4Transitional fossils are important in the study of evolution because they show traits common to both ancestral and descendant groups. This helps to trace the evolutionary history of a species.## Step 5The Tiktaalik fossil is significant because it shows characteristics of both fish and tetrapods. This fossil provides evidence of the evolutionary transition from water to land.## Step 6Biogeography is the field of study that examines the distribution of species across different geographical areas. This helps to understand how species have evolved and adapted to different environments.## Step 7The finches on the Galápagos Islands evolved distinct beak shapes and sizes by adapting to specific food sources on their respective islands. This is an example of natural selection in action.## Step 8Homologous structures in different species suggest common ancestry. This is because these structures have similar structures but different functions, indicating that they evolved from a common ancestor.
