What are the 4 main principles of natural selection
Natural selection is based on four main principles which are variation, overproduction, adaptation, and descent with modification. Variation is defined as any difference between the individuals in a species or groups of organisms of any kind of species.

Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure ...

The gene theory is the idea that the characteristics of living organisms are controlled by genes, which are passed from parents to their offspring. A gene is a segment of DNA that has the instructions to encode a protein. Genes are located on larger structures, called chromosomes, that are found inside every cell.Chromosomes, in turn, …Darwin’s observations that led to his theory of natural selection are: Overproduction – all species will produce more offspring than will survive to adulthood. Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.The Theory of Evolution by Natural Selection The theory of evolution by natural selection is a theory about the mechanism by which evolution occurred in the past, and is still occurring now.

VISTA. Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring. Although no one, including Darwin and Wallace, knew how this happened at the time, it was a common understanding.
