Artificial selection is an intentional breeding for specific traits or combination of traits.


Why so serious?

Do you know what these artificially selected Persian cats (above) has been through? A lot of suffering from respiratory problems and eating disorder. They are often bred for extremely flat faces and this cause problems. Not only the Persian cats, other plants and animals suffer from artificial selection as well! Look to your left and see a surprise! I can't help but pity the poor thing. Animals should originally be in the wild and roam free from restrictions, and not categorized as part of the human society. Unfortunately, these listed traits that are bred for don't help the animals survive in the wild AT ALL. Yet, they are extremely pampered and loved by their owners - well, not the ones you can eat which are most of them. How sweet.

The process of artificial selection essentially removes variation in a population. The animals can be especially susceptible to diseases or changes in the environment that would not be a problem for a natural population. There are also breeders who practice inbreeding between closely related individuals that cause problems, as well. Problems range from shorter life span to hip dysplasia. Without variation, everything would ceased to exist.

It not only affects the animals, what you eat are most likely be artificially selected. In agriculture, plants - corn, wheat, soybeans were bred carefully. Did you know that cabbage, broccoli, cauliflower, brussel sprouts, and kale are all members of the same species? Yea, I didn't know that myself.

I can see why artificial selection is deemed as bad but it can also do good. Sometimes it's not even a big of a deal however, it only benefit us, humans. A simple dog breeding is an example of artificial selection and that has been around for generations and generations.

I believe everything in this little-big world of ours are connected, such as, these lovely topics. The first post talks about biodiversity - which I've stressed how our world has changed drastically. The second pretty much tells the beginning of the end. I'm pretty sure, that a huge amount of the human population has realized how shallow and selfish we can really be, yet, rarely do we change. We try but it does more harm than good. We are (pathetically) humans, therefore, we like things that benefits us even if others suffer as a result, sadly.

The Princess
Hello my name is Princess and I'm a relatively good girl. I have an absolutely sweet tooth and I like chocolates and candy floss although they make me look kiddish most of the time. I am irrationally and irrevocably in love with you but the unrequited love tears me apart.
