Neo-Darwinism states that "evolution is driven by random genetic mutations followed by the weeding out of unfavorable variations by natural selection." [1]
The term evolution can have different meanings, such as “change over
time” or even “progress.” However, in modern biology, evolution centers on two ideas. The first is that all the organisms we see are descended from a single common ancestor somewhere in the distant past. The second foundational idea is that an unguided process of natural selection (“[[survival of the fittest]]”) has the power to produce fundamentally new forms of life through random mutations. This view of evolution is known as “Neo-
Darwinism.” [2]
