What is natural selection?
Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
Who proposed the theory of natural selection?
Charles Darwin proposed the theory of natural selection.
What is selective breeding?
Selective breeding is the human practice of breeding animals or plants that have certain desired traits.
How does natural selection differ from selective breeding?
Natural selection occurs naturally without human intervention, while selective breeding is a human-driven process to enhance specific traits.
What is an example of natural selection?
An example of natural selection is the development of antibiotic resistance in bacteria.
What is an example of selective breeding?
An example of selective breeding is the breeding of dogs to produce specific breeds with desired characteristics.

What role does the environment play in natural selection? | The environment determines which traits are advantageous, influencing which organisms survive and reproduce. |
Can selective breeding lead to negative consequences? | Yes, selective breeding can lead to reduced genetic diversity and increased susceptibility to diseases. |
What is a common goal of selective breeding? | A common goal of selective breeding is to enhance productivity, such as increasing milk yield in cows. |
Why is genetic variation important in natural selection? | Genetic variation is crucial because it provides the raw material for natural selection to act upon, enabling adaptation to changing environments. |
