- Directly caused by the environment.
- Acquired during an organism's lifetime.
- Random and heritable.
- Always beneficial for survival.

- Random mutations would lead to stronger beaks.
- The beaks would gradually strengthen and become more robust through use, and this trait would be inherited.
- Only birds with naturally stronger beaks would survive.
- The environment would directly cause the beak to strengthen.
- Traits are randomly inherited from parents.
- Traits developed during an organism's lifetime can be passed to offspring.
- Only traits present at birth are heritable.
- Environmental factors have no influence on heredity.
- Sexual reproduction.
- Complex multicellularity.
- The RNA world hypothesis.
- The DNA world hypothesis.
- They demonstrate complex cellular respiration.
- They show how simple organic molecules can self-assemble into membrane-bound structures.
- They are capable of true genetic replication.
- They prove the existence of extraterrestrial life.
- The change in an individual organism over its lifetime in response to the environment.
- The process by which species change over generations due to changes in their heritable traits.
- The development of complex technology by human societies.
- The spontaneous generation of new life forms from non-living matter.
- A medium for organic molecule dissolution.
- The necessary energy for chemical reactions.
- A protective layer against UV radiation.
- A source of carbon atoms.
- Individual plants will shiver and adapt to the cold, passing this adaptation to their offspring.
- All plants will eventually develop frost resistance.
- Plants with pre-existing genetic variations for cold tolerance will survive and reproduce more, increasing cold-tolerant offspring.
- The colder temperature will cause plants to mutate into cold-resistant forms.
- Traits are inherited.
- Organisms change over time.
- Somatic changes can alter germline genetic information.
- The environment plays a role in adaptation.
- Proteins were the first self-replicating molecules.
- RNA molecules could have performed both informational and catalytic roles in early life.
- DNA is more stable than RNA.
- Coacervates were the first living cells.
- Individual insects become resistant by adapting to the pesticide.
- The pesticide causes beneficial mutations for resistance.
- Insects with pre-existing genetic resistance survive and reproduce, increasing the resistant gene frequency.
- Resistant insects migrate into the population from elsewhere.
- How individuals adapt to their environment during their lifetime.
- The inheritance of acquired traits.
- How populations change over successive generations due to differential survival and reproduction.
- The sudden appearance of new species without prior ancestors.
- Are physically strongest.
- Have the longest lifespan.
- Produce the most viable offspring.
- Consume the most resources.
- Random mutations leading to eye reduction.
- Disuse of eyes in a dark environment leading to their degeneration and inheritance of this trait.
- Survival advantage of blind fish.
- Genetic drift in a small population.
