Species change over time. Postulate 2. All organisms are related by descending from a common ancestor. Postulate 3. Evolution is gradual. Postulate 4. Evolution leads to new species. Postulate 5. The primary mechanism for evolution is natural selection.Natural selection is no more, no less, than the changing representation of alleles that code for traits selected for by the environment. It is not a “force,” although “evolutionary force” is an expression that is often used to describe it.

(b) Use this estimate to find the maximum speed limit in the turn under the worst wet-ice conditions.Natural Selection: Natural selection is the explanatory principle describing how evolution occurs. It was proposed by Charles Darwin as part of his theories on the evolution of various species. While other scientists supported evolution during Darwin's life, they could not explain how the processes happened.

The 4 postulates are: 1- Individuals in population vary:population is a group of organisms occupying a place at once.Darwin called it natural selection and implied it as a mechanism of evolution. Fitness is the end result of the ability to adapt and get selected by nature. The fitness, according to Darwin, refers ultimately and only to reproductive fitness.
