Yes, natural selection is always occurring.
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.

It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
Evolution is the observed effect of natural selection acting on reproductive variation. Natural selection is a continuous process. The rate at which natural selection changes allele frequencies depends on the effect of the allele in the world. If the allele considered provides a significant reproductive benefit when compared to rival alleles, it will spread throughout the population gene pool much faster than the rival alleles.
According to the theory of natural selection, the primary factor responsible for biodiversity is the process of adaptation to varying environments over time, which is driven by genetic variation and survival pressures. While invasive species can affect biodiversity by introducing competition and altering ecosystems, the fundamental mechanism of biodiversity arises from the diverse adaptations of organisms to their specific ecological niches. Thus, natural selection plays a crucial role in shaping the vast array of life forms we see today.

yeah its occurring in Darfur
