Evolution: Theories, Types and Examples

Abstract

Harmony is a two-way evolutionary change involving two or more
species. Trend is the result of the interaction between them. The
various interactions that exist between biology - competition,
exploitation and reciprocity - lead to significant results in evolution
and diversity in relation to questions. Some examples of evolutionary
systems involve the relationship between parasites and their hosts,
plants and herbivores that feed on them, or the antagonisms that
occur between predators and their prey. Covariance is thought to be
responsible for a number of different phenomena, of which we today
appreciate the variety created by the interaction between species. In
practice, proving that dialogue is a matter of harmony is not an easy
task. Although the interaction between the two species is seemingly
perfect, it is not reliable evidence of coevolveary process. One
approach is to use phylogenetic studies to test whether there is a
single pattern of such diversity. In many cases, when the phylogenies
of two species coexist, it is assumed that there is harmony between
the two lineages.
