Survival of the fittest. Only the strongest/healthiest of a species survive and reproduce. This means that their genes are passed along to the next generation resulting in more animals with the same health/strength traits. Thus weaker animals slowly die out.
Meiosis plays an important role in the process of natural selection, as it allows DNA to replicate.
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.
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.
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.
Non-existent. Biological evolution is mediated by natural selection, and, ultimately, by the very laws of physics themselves. Chance may play *some* role in the process, but it is not all of the process.
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. ''

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.
Disruptive Selection
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.
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.
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.
