It means our centre or bass of evolution.
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.

An individual organism moves into a new population
Different ways for evolution to occur exist due to various mechanisms such as natural selection, genetic drift, gene flow, and mutation. These mechanisms can act independently or in combination to drive changes in populations over time. Additionally, environmental factors play a significant role in determining which mechanisms are most prominent in a particular population or species.
The main mechanism of adaptive change is natural selection. There are other mechanisms of evolution though Google ' mechanisms of evolution. '
Evolution can occur at the level of populations rather than individuals. Changes in allele frequencies within a population over generations is the basis of evolution, and this can happen through mechanisms like natural selection, genetic drift, and gene flow.
For evolution to occur, there must be genetic variation within a population, inheritability of these genetic traits from one generation to the next, differential survival and reproduction based on these traits (natural selection), and long periods of time for changes to accumulate across generations.
Evolution is a population-level process because it involves changes in the gene frequencies of a population over generations. Individual organisms do not evolve, as they do not pass on acquired traits to their offspring. Evolution occurs through mechanisms such as natural selection, genetic drift, and gene flow that act on the variation within a population.
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
The leading theory concerning the mechanism of evolution is natural selection.
The tempo and mode of evolution are interconnected in the development of species. Tempo refers to the speed at which evolutionary changes occur, while mode refers to the patterns and mechanisms of those changes. The relationship between tempo and mode of evolution influences how quickly and in what ways species evolve over time.
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
One factor that contributed to the slow pace of evolution over the 2 billion years of life on Earth was the limited genetic variation and the lack of mechanisms for rapid adaptation. Without mechanisms such as sexual reproduction or mutations, organisms were constrained by their existing genetic blueprints, which limited the speed at which significant evolutionary changes could occur.
The vast majority of scientists support evolution. There is no longer any debate in the scientific community about whether evolution occurs, only the mechanisms in which evolution acts upon is debated.
