artificial selection and genetic engineering

Artificial selection is where an intelligent creature uses the basis of natural selection to make traits, usually beneficial to the organism, more likely to appear in a controlled population. In this essay I will discuss artificial selection and genetic modification (GM) technology with dogs and the many vegetables bred from wild mustard as real world examples of artificial selection.  Process People breed organisms together that have the preferred traits so the trait is more common in the offspring. For example humans have bred wolves to be more docile and eventually to be useful in specific situations like herding, hunting, or pulling a bobsled. Another example of artificial selection is the variety of vegetables that were bred from wild mustard, including broccoli, kale, brussels sprouts, and cauliflower. All these many varieties were caused by humans breeding for specific traits, as broccoli, kale, and Brussels sprouts were created with a feature in mind: florets, leaves, and b...

Artificial Selection

  Introduction       Artificial selection is when an organism (usually a human) selectively breeds another organism to have more desired traits in a controlled population. Process         The process of artificial selection 10,000 years ago was fairly simple. A farmer would plant the seeds of a more desirable plant from the previous harvest, and so over time the crops become better for human consumption. For instance, the ancient Greeks and Romans bred wild mustard to have bigger leaves. This “wild cabbage” would be bred into many different brassicas including broccoli and cauliflower, true cabbage,  kohlrabi,  kale, and many more. On another note, dogs were also extensively bred. They were probably domesticated 40,000-30,000 years ago as companions and hunters and were bred to get better at those jobs, but in the Victorian era they were bred for looks at dog shows.       One hu...
