Question

Match each scenario with a component of natural selection. (4 points)
There is a field full of rabbits. They reproduce leading to an increase in population, but there's only so much clover to eat. This leads to competition!
Over time, there are more brown rabbits because they pass their genes to their offspring.
This helps the rabbits survive in the field.
Some rabbits are brown, some are almost white. This difference is due to variations in their genes.
Hawks love to eat white rabbits. Brown rabbits, hidden in the grass, survive longer and have more offspring.
:: Genetic variation
： Selection
When are two individuals considered to be the same species? (1 point)
• They are able to produce offspring.
• They have a similar number of chromosomes.
• They have a recent common ancestor.
• They are able to produce fertile offspring.
Use the following graph to answer the next 2 questions:
:: Overproduction
： Adaptation

Answer 1

Matches:
- Overproduction: "There is a field full of rabbits... they reproduce leading to an increase in population, but there's only so much clover to eat. This leads to competition!"
- Genetic variation: "Some rabbits are brown, some are almost white. This difference is due to variations in their genes."
- Selection (differential survival): "Hawks love to eat white rabbits. Brown rabbits, hidden in the grass, survive longer and have more offspring."
- Adaptation: "This helps the rabbits survive in the field." (the brown coloration is an adaptation)

When are two individuals considered the same species?
- They are able to produce fertile offspring.
