According to Alfred Wallace’s Theory of Evolution, elements that stronger then other in an environment are more likely to continue to exist by being passed down from one generation to another generation. Just like Darwin’s theory factors such as variations play a large role in Wallace’s.
Variations can be factors that can range from environmental, physical, and social backgrounds (Ashford, LeCroy, Lortie 2001). These variations can lead us to learn why it is species has changed over time, why the change transpired, as well as why the factor lead to the species surviving. No one variation is going to be the same with will result in different one species getting a different evolution that another. A biological example of this would be Darwin’s research done in on the Galapagos Islands. A behavioral example of this would be children learning what behaviors are socially acceptable behaviors in public
