Difficulty: EasyDarwin's Theory of Natural Selection

Match each core concept of Charles Darwin's theory of natural selection on the left with its corresponding description on the right.

  • OverproductionOrganisms produce more offspring than the environment can support.
  • Struggle for existenceIndividuals compete for limited environmental resources such as food and space.
  • Survival of the fittestOrganisms with advantageous traits are more likely to survive and reproduce.
  • Inheritance of variationFavorable inherited traits are transmitted from parents to subsequent generations.

Answer

Overproduction matches with organisms producing more offspring than the environment can support; Struggle for existence matches with individuals competing for limited environmental resources; Survival of the fittest matches with organisms with advantageous traits being more likely to survive and reproduce; Inheritance of variation matches with favorable inherited traits being transmitted to subsequent generations.
Each core concept of natural selection directly aligns with a key evolutionary process: overproduction creates resource pressure; scarce resources lead to competition (struggle for existence); advantageous traits enable differential reproductive success (survival of the fittest); and passing those favorable traits to offspring alters population characteristics over time.

Step-by-Step Solution

1
Define overproduction within Darwin's theoretical framework.
Species have a natural tendency to produce more offspring than their habitat can sustain.
High reproductive potential creates population pressure against finite natural resources.
2
Identify the primary consequence of overproduction and limited resources.
Organisms must engage in a struggle for existence.
Scarcity of essential resources like food, light, and shelter leads to competition.
3
Relate individual differences to survival outcomes.
Organisms with advantageous variations undergo differential survival (survival of the fittest).
Traits that better adapt an individual to its environment increase its probability of surviving and reproducing.
4
Explain how natural selection affects future generations.
Advantageous variations are inherited by offspring.
Heritable favorable traits become increasingly common in subsequent generations.
