The correct Answer is:
To determine which statements support the view that elaborate sexual reproduction processes appeared much later in organic evolution, we can analyze each statement one by one. ### Step-by-Step Solution: 1. **Understanding the Evolutionary Context**: - Early life forms were simple and unicellular. As evolution progressed, more complex multicellular organisms developed. This context is crucial for evaluating the statements. 2. **Evaluating Statement i**: - **Statement**: Lower groups of organisms have simpler bodies. - **Analysis**: This is true. Simpler organisms (like unicellular ones) are typically found in lower groups of the evolutionary hierarchy. They tend to reproduce asexually, which is a simpler process. 3. **Evaluating Statement ii**: - **Statement**: Asexual reproduction is common in lower groups. - **Analysis**: This is also true. Lower organisms, due to their simple structure, often reproduce asexually to quickly increase their population, which enhances survival chances. 4. **Evaluating Statement iii**: - **Statement**: Asexual reproduction is common in higher groups of organisms. - **Analysis**: This is false. Higher groups (like mammals and angiosperms) predominantly reproduce sexually. Asexual reproduction is less common in these groups due to their complex structures and the need for genetic variation. 5. **Evaluating Statement iv**: - **Statement**: The high incidence of sexual reproduction occurs in angiosperms and vertebrates. - **Analysis**: This is true. Angiosperms (flowering plants) and vertebrates (like mammals) exhibit a high incidence of sexual reproduction, which aligns with the idea that sexual reproduction became more prevalent in more complex organisms. 6. **Conclusion**: - The statements that support the view that elaborate sexual reproduction processes appeared later in organic evolution are: - i. Lower groups of organisms have simpler bodies. - ii. Asexual reproduction is common in lower groups. - iv. The high incidence of sexual reproduction occurs in angiosperms and vertebrates. ### Final Answer: The correct statements are i, ii, and iv.
