Charles Darwin's Theory Of Evolution By Natural Selection

Good afternoon, Prof. Norton & Class,

If adaptation improves a species success, why do species go extinct instead of adapting and surviving?

In this week’s lesson and reading resources, we covered a multitude of information regarding evolutionary theory. I took biology several months ago, and we talked about the theory of evolution. There are several theories based on our existence but what theory we believed was entirely up to us. This week we discussed Charles Darwin’s theory of evolution by natural selection. Darwin’s theory of national selection is based on all living things are descendants of one species through survival traits being passed down from one generation to the next. The species that survived would have

Observing the timeline, we know that several different species branched off from one another. Several different species are the direct result of genetic variation. Genetic variation is a key in natural selection. There must be a variety of species with different genetic variations for one species traits to survive its current environment. What causes genetic variation? Genetic variation arises when a random gene mutation occurs creating a species that differs slightly from the previous one. These species with their genetic differences try to adapt to the current environment. The species with the most favorable traits will survive while the species with the less desirable trait will eventually go extinct. Genetic variation can also lead to speciation which is the development of an entirely new species factoring time, genetic differences, and the environment. Adaptation is the species ability to adapt to its changing surroundings. While adaptation can be beneficial to a species success, it boils down to the favorable traits that a species has that will help them survive. If the environment quickly changes and the species does not contain the survival traits needed to survive the advanced environment than the species will most likely go
