Natural selection plays a huge role in evolution.  Natural selection is a process in which favorable variations for a particular environment survive, reproduce, and pass these variations of to following generations.

This is significant to me because if you know the process of natural selection that you have a better understanding of how organisms evolve.

Descent with modification means that offspring look different from their parents because of a genetic mutation.

This is significant because without descent with modification species would vary in little amounts. This was an important observation for all species.

Common descent is the theory that every living thing on earth is related to a common ancestor.  This is significant because of the similar anatomy, embryology, fossil records, and DNA between different species.  This would explain why there are so many similarities.

Evolution evidence such as anatomy, embryology, fossil records, biogeography, and biological molecules (DNA) are also important.  They are important because they show similarities between very different species, such as the whale and a hippo.  Evolution evidence helps confirm the theory of common descent.

Different structures such as homologous, analogous, and vestigial structures provide evidence for evolution also.  Homologous structures, for example, have common evolutionary origin, analogous structures have different evolutionary origin but are similar in function, and vestigial structures seem to serve no function but resemble structures that have/had functional roles in related organisms, such as the human tailbone and appendix.

This is important because it is evidence of evolution and common descent.  The similar structures in different organisms is an outstanding discovery.

The two claims of evolution are that all living things are related, also known as common descent, and that evolution is powered by natural processes.  These claims pave the way for more scientists to come up with ways to observe evolution.

Charles Darwin is considered to be the founder of the modern theory of evolution.  He made observations of finches and the Galapagos Islands to provide evidence for his theories.

Although his observations are very important to science, knowledge of the subject has advanced and people have critiqued his observations.  This is also just a minor part of my knowledge about evolution.

Natural selection in humans has occurred.  For example, areas with more people that have sickle cell anemia have more protection against Malaria.  Tony Allison’s observations proved that a mutation for one disease can help protect you from another disease.

Structural adaptations such as mimicry and camouflage have allowed some animals to be more likely to survive than others.  Mimicry is when an organism copies the appearance of another organism.  Camouflage is when an animal blends in with its surroundings.

Evolution repeats itself and never ends.  Evolution is always happening, and organisms are changing right before our eyes.

This is the least important to me because although it is a key fact, it is pretty obvious considering the changes of organisms around us.
