<u>mechanism:</u> the process of evoluton .
Evolution is the process by which veriety of modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all 0rganisms and the amazing diversity of that organisms but exactly how does it work? Fundamental of the process of evolution is genetic variation upon which selective forces can act in order for evolution to occur.
Examines the mechanisms of evolution focusing on:
•<u>Decent </u>: the genetic differences that are heritable and passed on to the next generation successfully.
• <u>mechanisms of change</u>: Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .
• The random nature of genetic drift and their effects .
• How variation, differential reproduction, and heredity result in evolution natural selection
.
• How different species can affect each other's evolution through co-evolution.
All of these mechanisms can cause changes in the frequencies of genes produce change in in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.

The etheric body
The etheric body is the layer of the human energy field that is most closely associated with the body's blueprint of physical health and is found closest to the physical body.
The etheric body is the first layer of the human energy field that is found to be in immediate contact with the physical body. The ether body is the energy system for the physical body as it sustains it, joins it with higher bodies and functions as the matrix for physical metabolic activities.
Secondary succession is the infer kind of succession that will take place on an abandoned, unpaved country road.
Secondary succession is termed as one of the two types of ecological succession in the life of a plant.
It is a process which is being started by an event for example harvesting, hurricane, and forest fire. which reduces an established ecosystem. Secondary succession occurs in a pre-existing soil and it is the ecological succession that occurs after the initial succession which has been disrupted and some animals and plants still exist.
