Natural selection is the natural process of living organisms who cannot function efficiently dying off.
For example if a giraffe isn't tall enough to reach the leaves on a tree it won't be able to eat and end up dying of starvation. Natural selection also deals with evolution and the overall health of a population. Sense the animals who can't survive die off they don't get a chance to reproduce and have offspring that could potentially be born with the same inabilities that keep them from surviving. Overtime natural selection should make a population stronger however it the group of organisms are all unable to survive natural selection will cause them to go extinct.
Summary
I have learned that natural selection occurs in all living organisms, not just animals but plants and cells too. It doesn't matter what organism it is if it isn't able to do what it needs to survive eventually it will die and leave the stronger organisms who survived to reproduce. This minimizes the chance of another organism that can't survive on its own being born.

Does this mean that natural selection has happened through out the evolution of humans? Are there certain traits that we all have from natural selection?
ReplyDeleteYes natural selection has been present all throughout humans history and is actually the cause for evolution. If we can't survive in a certain situation we have to adapt to survive. One evolutionary trait we as humans have is the ability to think and use tools, because of this adaptation we can survive in most environments.
DeleteDoes natural selection occur in different ways depending on the time period? How fast can the process occur?
ReplyDeleteNatural selection occurs in many different ways based on the environment and because the environment changes over time natural selection has also occurred in different ways over time. Natural selection can be as slow as evolution or as fast a bad decision that leads to death.
