Life is constantly changing. A few of these changes can include environmental changes, animals adapting and adjusting to live as fit. In fact, one of the most common pest, bed bugs, can be an example of Charles Darwinism's evolution theory. In case you didn't know, bed bugs are small brown bugs that feed on animals or humans. In fact, the bed bug's history is quite interesting.

Back then, bed bugs lived in caves and fed on bats. However, as early humans came to live in caves, bed bugs turned their attentions to their new hosts. As they followed humans around, they slowly changed, adapting by sleeping by day and feeding at night. In fact, scientists noticed a difference between the bed bugs and their diets. Those who fed on bats had stronger legs than ones who fed on human, due to the fact of hanging upside down with the bats. Also, bed bugs with lived with humans had a much shorter life span than the ones who fed on bats. Since these bugs adapted quite quickly, scientists can't help but wonder if these bugs will change once again, having resistance of pesticide and creating another branch of bed bugs.

I honestly find it amazing how something so small can adapt and adjust living longer than humans had. Also, how well Charles Darwinism's theory is, still applying to even today. It makes me wonder if we human will continue to adapt and maybe change our behavior just like the bed bugs did.
