Variation within populations, heritability of traits, and differential reproductive success are the key characteristics that lead to natural selection. Variation allows for the existence of different traits, heritability ensures that these traits can be passed on to offspring, and differential reproductive success means that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to the next generation.
Natural selection is a process where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this leads to the evolution of populations as certain traits become more common. This process helps shape the characteristics of individuals within a population, as those with beneficial traits are more likely to thrive and pass on their genes.
Variations within populations is what natural selection is " looking " for. That one variant of a population is somewhat better able to survive and reproduce than other variants against the backdrop of the immediate environment is natural selection.
When microevolution occurs over many generations, inherited characteristics can lead to changes in populations. This can result in the adaptation of populations to their environment, leading to the emergence of new traits and the evolution of new species. This process drives biodiversity and is driven by natural selection acting on genetic variation within a population.
Charles Darwin introduced the concept of biological evolution through natural selection in his book "On the Origin of Species" published in 1859. Darwin proposed that species evolve over successive generations through the process of natural selection acting on variations within populations.
Variation in traits within populations is the characteristic that causes natural selection. This variation could be due to genetic differences or environmental factors, and individuals with traits that are better adapted to their environment are more likely to survive and pass on their genes to the next generation. Over time, this process leads to the evolution of populations as adaptations become more common.

Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.

The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.

Natural selection plays a key role in shaping the characteristics of organisms within biomes. It helps organisms adapt to their environments over time by favoring traits that increase their chances of survival and reproduction. This process contributes to the diversity and equilibrium of species within a biome.
Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
Disruptive selection is a type of natural selection that favors extreme traits over the average trait, leading to the divergence of characteristics within a population. This process can result in the formation of two distinct phenotypic groups with reduced variation between them.
Natural selection does not result in populations achieving perfect adaptation to their environment because the environment is constantly changing, which means that what is considered advantageous in one situation may not be advantageous in another. Additionally, genetic variation within a population means that not all individuals will have the same traits that are best suited for a particular environment.
the factors that are necessary for natural selection by evolution to occur are: 1)variation in characteristics;different individuals in a population must have different characteristics. 2)differencies in fitness different characteristics of different individuals must contribute to differences and fitness. 3)heritability of characteristics characteristics that affects fitness must be heritable.... example:passed by genes from one generation to the next)
