Evolution is a process by which changes occur in a species, one that shares a specific habitat, over time. By definition, evolutionary changes only occur on the genetic level, however, particularly with modern-day humans, it is also important to understand neo-evolution, which pertains more to the evolution of societies and development of widely separated cultures. We will first focus on genetic, or conventional, evolution.
Genetic adaptations are generally the result of gene mutations or combinations through reproduction that provides an organism with a survival advantage. The result is these advantageous characteristics appearing recurrently in a population, eventually culminating in the fortification of a species, or perhaps the birth of an entirely new one. This birth is explained through the concept of the “tree of life” – a notion that all organisms have adapted and evolved from a single common ancestor. Ultimately, all life forms are unified, despite its frequent disorganization of possible evolutionary
