Evolution has two key driving forces without which it would not occur, but with which it must occur:
The first is reproductive variation: this basically asserts that each organism is slightly different from both its parents and its siblings.
The second is differential reproductive success: this asserts that features that allow their bearers to reproduce more successfully than members of the same species with different features are likely to be present in a greater part of the population in coming generations.
In other words: the key driving forces behind evolution are variation and selection.
Natural Selection.

Answer 1The most important directional "force" in evolution is natural selection, or differential reproductive success.Under natural selection I include sexual selection. Note that other people may list these two forms of selection under separate headers. Sexual selection is when organisms display preferences for mates with specific attributes, such as a colourful plumage, or broad hips and large mammaries.
Evolution is the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms.
Perhaps you mean group evolution, your question is unclear. It is also important to note that most evolutionary biologists don't believe group evolution happens.
the most important, the conversion of Carbon Di-oxide to Oxygen!
Spontaneous evolution is evolution that is not moderated by intentional beings and actions. Most evolution, in other words. Usually we call non-spontaneous evolution (ie. evolution that *is* moderated by intent): breeding.
Jonathan Edwards is considered to be America's most important theologian. He was a critical force in the shaping of the First Great Awakening.

Tectonic processes have played an important role in shaping the physical landscape of east Africa.

The most important and strongest force of erosion is Water.
Neocortex is the region of brain only present in mammals , and most highly developed in humans , it is involved in all higher brains hence it is most important in mammalian evolution .
