Evolution by natural selection occurs when there is variation in traits among individuals in a population, heritable traits that can affect survival and reproduction, and differential survival and reproduction based on those traits.
Among the scenarios provided:
1. **Penguins reproduce sexually, producing offspring that look different from one another** - This scenario includes variation among offspring, which is essential for natural selection to occur.
2. **Corn is genetically modified and cloned to make identical crops** - Cloning produces identical individuals, so there is no variation for natural selection to act upon.
3. **A banana tree branch is planted, producing a clone of the parent tree** - Similar to the corn scenario, cloning results in genetically identical offspring, lacking variation necessary for natural selection.
4. **Microorganisms reproduce asexually, producing identical offspring** - Asexual reproduction in this case results in identical offspring, so again, there is no variation for natural selection.
In conclusion, the correct answer is:
**Penguins reproduce sexually, producing offspring that look different from one another**. This scenario allows for variation, which is crucial for evolution by natural selection to take place.
