Though living organisms tend to multiply geometrically, the number of individuals of a species tend to remain constant over a long period of time. Out of heterogeneous population (due to the variation) best adapted individuals are selected by nature.

Darwin and Wallace proposed the following sequence for organic evolution: Overproduction, constancy of population size, variations, and natural selection. Let's break down each component of this sequence and explain its significance in the process of evolution.
Overproduction:
- In any given population, organisms tend to produce more offspring than can survive to reproductive age.
- This leads to competition for limited resources, such as food, water, and shelter.
- Only a fraction of the offspring will survive and reproduce.
Constancy of population size:
- Despite the overproduction of offspring, most populations tend to maintain a relatively stable size over time.
- This is due to the fact that resources are limited and individuals face various challenges, such as predation, disease, and competition.
- The constancy of population size ensures that there is not an unlimited increase in the number of individuals within a population.
Variations:
- Within a population, there are naturally occurring variations in traits and characteristics.
- These variations can be inherited from parents or arise from random mutations.
- Variations can affect an organism's ability to survive and reproduce in its environment.
- Examples of variations include differences in body size, coloration, behavior, and resistance to diseases.
Natural selection:
- Natural selection acts on the variations within a population.
- Individuals with advantageous variations are more likely to survive and reproduce, passing on their traits to the next generation.
- This process leads to the accumulation of favorable traits over time and the adaptation of populations to their specific environments.
- Natural selection is driven by the differential reproductive success of individuals with different traits.
Significance of the proposed sequence:
- The proposed sequence highlights the key steps involved in the process of organic evolution.
- Overproduction and constancy of population size set the stage for competition and the selective pressures that drive evolution.
- Variations provide the raw material for natural selection to act upon.
- Natural selection, in turn, leads to the adaptation and change of populations over time.
In conclusion, the sequence proposed by Darwin and Wallace for organic evolution is overproduction, constancy of population size, variations, and natural selection. This sequence captures the fundamental processes that drive the diversity and adaptation of life on Earth.
