If it is easier or more likely that an organsim is going to survive and reproduce if that organism works together with another or takes advantage of a certain opportunity, natural selection will favor the organisms that are more suited to maintaining their realtionship with the other organism.
Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection. Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
Meiosis plays an important role in the process of natural selection, as it allows DNA to replicate.
The direction evolution takes is primarily determined by natural selection. This process favors traits that enhance an organism's survival and reproductive success, causing those traits to become more common in subsequent generations. Additionally, environmental factors play a role in shaping evolution by exerting selective pressures that favor certain adaptations over others.
Evidence of evolution began to be recognised as far back as the eighteenth century, but naturists could not yet identify an explanation for this evidence. Jean-Baptiste Pierre Antoine de Monet (1744-1829) was an early advocate of evolution and believed that it proceeded in accordance with natural laws.Thus Charles Darwin (1809-1892) was not the first to study evolution, but he was the first to recognise the role of natural selection in evolution. He had studied medicine, before dropping out and studying taxidermy, then natural history. His father enrolled Charles to study theology, hoping he would become a clergyman. Charles Darwin developed the Theory of Evolution by Natural Selection after observing the evidence for evolution during his voyage in HMS Beagle. The captain of the Beagle was already aware of evolutionary theories that were already beginning to shock Christian believers in Europe, and had hoped that by having a naturalist on board he might obtain geological evidence to refute the them. During the voyage, from 1831 to 1836, Darwin travelled hundreds of miles inland, from country to country, trying to interpret the fauna, flora and geological formations. He then spent a further twenty years gathering and investigating evidence before publishing his conclusions.Darwin's Theory of Evolution by Natural Selection says that species evolved over time in response to changes in the natural environment, and is seen by scientists as the best explanation for the facts. Darwin wrote Origin of Species in 1859 and The Descent of Man in 1871.The English naturalist Alfred Russell Wallace also invented the theory of natural selection, independent of Charles Darwin. However, he believed that natural selection did not apply to humans, because our evolution was divinely guided. In the years since, paleoanthropologists have found ample evidence that human evolution did occur as the result of natural selection, just as the evolution of all other species did.
The harsher the environment the more natural selection plays a role because the smallest advantage might be enough, hence humans with a very easy environment where genes don't offer a significant advantage this doesn't really count for humans. And how much a species reproduce, the more they reproduce the more chance for a beneficial mutation.
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

The environment is the '' natural selector. ''
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.
First, I should mention that 'micro-evolution' is not a process in itself. Rather, it is a perspective on the effects of evolution. 'Micro-evolution' is those effects seen from close-up; by 'zooming out' one sees those same results in a wider scope called 'macro-evolution'. All evolution is driven by genetic variation and natural selection. Natural selection drives evolution by filtering out some variations while promoting others, thereby directing the slow change of morphology and behaviour of populations.
The book , On the origin of Species, was the book that shook the world. The book challenged other evolution theories while discussing evolution and the role of natural selection in it.

because we adopt through evolution. also passing characteristics on their offspring is a key role for evolution.
Disruptive Selection
The direction evolution takes is primarily determined by natural selection. This process favors traits that enhance an organism's survival and reproductive success, causing those traits to become more common in subsequent generations. Additionally, environmental factors play a role in shaping evolution by exerting selective pressures that favor certain adaptations over others.
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
