When we think of evolution, we usually think of primates evolving into humans, and of the evolutionary changes that were made over thousands and thousands of years. But the truth is evolution is at work all the time. Sometimes the changes are small and appear insignificant at first glance, but they all play a part in natural selection and the survival of the species.
But natural selection doesn't lead to the development of a new species. In most cases, the process simply allows a species to better adapt to its environment by changing the genetic make up from one generation to the next. And the process is actually quite predictable. If a species lacks a certain trait that will allow it to survive, there are two options: Either the species dies out or it develops the missing trait.
Most people think of biologist and naturalist Charles Darwin as the father of the theory of evolution, but the truth is that the concept of evolution is much older. Anaximander, a philosopher who lived in Ancient Greece, believed that man naturally evolved from an early animal species [source: All About Science]. And in 1809, biologist Jean-Baptiste Lamarck talked about the transformation of one species into another. But it was Darwin who introduced the concept of natural selection in the 1850s and forever changed the concept of evolution. Read on to see 10 prime examples of this theory and how each species puts its own spin on it.
Accidental selection is the process of evolution in a subset of a species due to circumstances like a natural disaster.
Charles Darwin is associated with the theory of evolution by natural selection, which explains how species evolve and adapt to their environments over time through the process of natural selection. He is best known for his work on the origin of species and the idea that all living organisms are descended from a common ancestor.
One long argument with supporting evidence for the theory of evolution by natural selection. Starting with artificial selection, used as an analogue for natural selection, and ending with the distribution of animals, biogeography, Darwin showed the species arose through natural process over long lengths of time.
Darwin called his theory "natural selection" or "survival of the fittest." It explains how species evolve and adapt to their environment over time through the process of natural selection.

Selection is the process throughout evolution that results in a species existing in a current ecosystem at a given time. This is known as natural selection.

The process is called natural selection, where environmental pressures lead to certain traits being favored and passed down to future generations through genetic adaptation. This process helps species become better adapted to their environment over time.

Adaptation (I'm studying the same thing ;)
Natural selection may ultimately be his downfall.
