Yes, populations evolve. Individuals/genes are selected.
The smallest unit in which evolution occurs is a population.
The smallest biological unit that can evolve over time is an individual organism, typically a unicellular organism like bacteria or archaea. These organisms can undergo genetic mutations and natural selection, leading to the evolution of their populations over generations.
Evolution is defined as a change in allele frequencies over time. Since individuals have only the set of alleles that they're born with, an individual cannot evolve. This leaves the population as the smallest unit that can evolve.
The smallest biological unit that can evolve over time is a population. Evolution is the change in the heritable characteristics of a population over generations. Individuals do not evolve, but rather the frequency of traits within a population changes over time.
Population is the unit of evolution. A population is defined as a group of organisms of a particular species that inhabits a particular area. Natural selection acts on traits within that population that are beneficial in the particular area. Another population of the same species may be under different selective pressures (as it is found in a different location), and natural selection may therefore act on different traits within that second population. The two populations, thus, may evolve differently. Therefore, the unit of evolution is the population, not species.
The smallest group of organisms wherein evolution can take place is a population. This is because all methods of evolution require chromosomes from more than one organism.
Is a population. Consider the definition of evolution.Evolution is the change in allele frequency over time in a population of organisms.
Evolution occurs at the population level, not at the level of an individual organism or a species. Changes in gene frequencies within a population over time drive the process of evolution.

Evolution on the smallest scale refers to changes in the genetic composition of a population that occur over a short period of time, such as within a single generation. This can involve processes like genetic drift, gene flow, and natural selection acting on a small group of individuals.

The smallest unit of ecological organization is an individual organism. This could be a single plant or animal that interacts with its living and non-living environment within a specific ecosystem.
