- When an organism reproduces they pass their traits to their offspring
- If an organism survives competition for resources then this organism will survive / reproduce for natural selection
- So, if an organism survives competition for resources then this organism will survive / reproduce for natural selection and pass their traits to their offspring

- If an organism survives competition for resources then this organism will survive / reproduce for natural selection and pass their traits to their offspring
- Beneficial traits allow organisms to survive competition for resources
- So, natural selection is when organisms with beneficial traits survive competition to reproduce and pass their beneficial traits onto their offispring

- A generation is a group of organisms who are born and live at relatively the same time
- An organism and it's offspring are born and live at relatively different times
- Hence, an organism and its offspring are part of different generations

- An organism and its offspring are part of different generations
- An organism passsing its traits to its offspring is a kind of process
- So, an organism passing its traits to its offspring is a kind of process that involves organisms from different generations

- An organism passing its traits to its offspring is a kind of process that involves organisms from different generations
- Processes that involve organisms from different generations take place over a period of at least 1 to many generations
- Hence, the process of an organism passing traits to offspring occurs over a period of at least 1 generation to many generations

- Natural selection is when organisms with beneficial traits survive competition to reproduce and pass their beneficial traits onto their offispring
- The process of an organism passing traits to offspring occurs over a period of at least 1 generation to many generations
- So, natural selection occurs over a period of 1 to many generations

- Natural selection occurs over a period of 1 to many generations
- To a human a time period of 1 generation to many generations is considered very long
- Hence, natural selection occurs over a period of 1 to many generations which is considered a very long time to a human

Hence, natural selection occurs over a period of 1 to many generations which is considered a very long time to a human
Question: Which statement best describes the theory of natural selection?
Context: - A generation is a group of organisms who are born and live at relatively the same time 
- When an organism reproduces they pass their traits to their offspring 
- Processes that involve organisms from different generations take place over a period of at least 1 to many generations 
- If an organism survives competition for resources then this organism will survive / reproduce for natural selection 
- An organism passsing its traits to its offspring is a kind of process 
- To a human a time period of 1 generation to many generations is considered very long 
- Beneficial traits allow organisms to survive competition for resources 
- An organism and it's offspring are born and live at relatively different times
