- Individual bacteria would acquire resistance by adapting to the antibiotic and pass this resistance to their offspring.
- Random mutations would arise, making some bacteria resistant, which then survive and reproduce.
- The antibiotic would cause bacteria to become more susceptible to other antibiotics.
- Bacteria would actively choose to become resistant.
- They would grow naturally taller and less bushy.
- They would inherit the tendency to be shorter and bushier.
- They would show increased resistance to diseases.

- Rabbits change their fur color to match the environment.
- Rabbits with fur color that blends with the environment are more likely to survive and reproduce.
- All rabbits eventually develop camouflage fur.
- The predator learns to ignore rabbits with certain fur colors.
- Directly causes beneficial mutations in organisms.
- Selects for individuals with pre-existing variations that are advantageous.
- Induces acquired characteristics in organisms.
- Provides a fixed blueprint for species evolution.
- All individuals in a population reproduce at the same rate.
- Individuals with advantageous traits are more likely to pass on their genes to the next generation.
- Only the largest individuals reproduce.
- Reproduction rates are solely determined by geographic location.
- The strongest and fastest individuals.
- Individuals best adapted to their environment.
- Individuals that can outcompete others for mates.

- Mating partners only.
- Resources, space, and mates.
- Avoiding predation exclusively.
- Achieving a higher level of complexity.
- All organisms in a population can successfully reproduce.
- Organisms produce more offspring than the environment can sustain.
- Every offspring produced will reach reproductive age.
- Genetic mutations lead to an excess of new traits.
- Adaptation to the environment.
- Change in species over time.
- Inheritance of traits.
- Differential survival and reproduction based on inherent variation.
- Eyes would gradually become larger and more sensitive.
- Eyes would gradually reduce in size and function due to disuse.
- Eyes would adapt by developing bioluminescent properties.
