The neutral theory of molecular evolution holds that most evolutionary changes occur at the molecular level, and most of the variation within and between species are due to random genetic drift of mutant alleles that are selectively neutral.
The Neutral Theory of Molecular Evolution is an influential monograph written in 1983 by Japanese evolutionary biologist Motoo Kimura.While the neutral theory of molecular evolution existed since his article in 1968, [1] Kimura felt the need to write a monograph with up-to-date information and evidences showing the importance of his theory in evolution.
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.

r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). [10]
For many molecular biology approaches, as opposed to mathematical genetics, neutral mutations are generally assumed to be those mutations that cause no appreciable effect on gene function. This simplification eliminates the effect of minor allelic differences in fitness and avoids problems when a selection has only a minor effect.

What Wagner calls "a fringe movement in evolutionary biology", [2] the form of structuralism exemplified by Brian Goodwin, [2] [21] effectively denies that natural selection is important, [2] [22] or at least that biological complexity could be reduced to natural selection. [22] [23] This led to conflict with Darwinists such as Richard Dawkins ...
