Natural Selection is the process by which an environmental factor acts on a population and results in some organisms having a greater chance of survival and producing more offspring than others. Many steps are involved and contribute to creating Natural Selection which is also known as the concepts of Darwinism. Variation plays a …show more content…
A specific reason for this is food. Competition is an interacting between species/organisms in which both are harmed. It consists of different species that both seek a limited supply of the one resource. This factor forces the organisms/species to fight for what they need so they can ensure safety and survival. Overproduction involves the organisms/species to produce too much offspring which results in limiting their survival chances which could include food, shelter etc.
Even to this day, evolution can be demonstrated by natural selection. Many examples support evolution in this modern time. One includes the colours of sharks. They are colours white on the underside and the top of the sharp consists of either blue or grey. Sharks have evolved and adapted to their environment by their colours. Their colours are their camouflage as the top blends with the colour of the water to somebody looking down into the water. Their white underside blends with the light coming through the water from above the water
