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.

What is the most important event in recent human evolution?
The most important event in recent human evolution is the development of agriculture, which led to the rise of civilizations and significant changes in human societies, lifestyles, and technology.
Which theory most strongly emphasizes the role of biology and evolution in development?
The evolutionary theory of development most strongly emphasizes the role of biology and evolution in shaping development. This theory suggests that behavior and development are influenced by our evolutionary history, genetic makeup, and adaptation to the environment over time.
What type of genetic change is most important for evolution?
Mutations are the most important type of genetic change for evolution. Mutations create genetic variation within a population, which is the raw material for natural selection to act upon, driving evolutionary change.
What is the primary directing force in evolution?
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.
What theory was Darwin's most important idea?
Darwin's most important idea was the theory of natural selection, which proposed that organisms that are better adapted to their environment are more likely to survive and reproduce. This concept is at the core of his theory of evolution by natural selection.
