coevolution
The ratio of beneficial traits tends to increase until each member of the species possesses the trait, at which point the trait is fixed.
Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.
Evolution is enabled by natural selection: the ability of a species through its individuals to make long-term improved changes in its response to its environment through beneficial mutations, resulting in the species being able to reproduce itself more successfully than before.
Symbiosis is an interaction between two different organisms living in close physical association, typically to the advantage of both. The relationship is normally mutually beneficial.

It is where both species benefit the other equally.
That would be the evolution of an exclusive symbiotic or parasitic relationship.

Geography can influence evolution by creating barriers that limit the movement of species, leading to genetic isolation and potentially the development of new species through natural selection. Different environments can also drive adaptation in species, with variations in geography providing diverse ecological niches for the evolution of different traits.

In nature a relationship between two organisms of different species is called symbiotic. These relationships can be both beneficial and harmful to one or the other. A relationship where one obtains a benefit without doing harm to the other is called commensalism. Where both species are benefitted it is called mutualism.
the series of adaptations and counter-adaptations that causes gene frequencies to change even without gene exchange; the interdependent evolution of two or more species having an obvious ecological relationship, often restricted to cases in which the interactions are beneficial to both species but also used for any evolutionary interaction between species having some degree of interdependence, such as a parasite and its host; the simultaneous evolution of interacting populations.

Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
yes, very dramatically. there is significant evidence that sexual reproduction is an evolutionary response to parasites.
