Selective breeding is when people (scientists) breed plants/animals for their traits. Its like strong horses being bred together or like white and red flowers to make pinks flowers. They can predict what the organism will turn out to look like. An example that ISN'T selective breeding is random flowers/animals that breed not caused by humans.

True, Darwin did realize that the observed variations among individuals within a population were caused by selective breeding. Although he did do a lot of great stuff. He wrote a book called The Origin of Species. You should check it out if you would like to find out the stuff that he did and what he found out about evolution. Either that or rent a book from a library about evolution.
