Answer:
Scientific model of natural selection applies to groups because pressures are experienced only to groups of individuals and not to individuals themselves.
Explanation:
Natural selection, linked to the evolution proposed by Charles Darwin, refers to the way in which different genotypes are presented in a population, subject to reproduction. In simple terms, genetic variations in a population, determined by the need to adapt to their environment, produce changes in the genotypic expression of later generations.
Groups of individuals of a species must be subject to the same environmental pressure and changes in their environment for natural selection to occur and be inheritable to subsequent generations. Changes experienced by a single individual are not significant for offspring within a population.
For natural selection to occur there must be certain conditions:
- <em>A characteristic in a species must be inheritable.
</em>
- <em>This characteristic, which belongs to a population, must be variable among the individuals who are part of it.
</em>
- <em>Survival and reproductive success depend on genetic variability among individuals of the same species.
</em>
Currently, the modern conception of natural selection discusses whether this selection occurs at the group level.
