You will see examples of selective breeding in greengrocers shops and florists. All the modern veg are produced from artificial selection. For example a swede is bred from a turnip and a cabbage. A swede would not have existed but for selective breeding.
  All the flowers that you see and buy are almost always the result of artificial selection by man. Most wild flowers are much smaller that "manmade " varieties and colours etc.
    A very good example in animals is of the domesticated grey wolf ( the dog) ,who has been artifically selected into hundreds of breeds. Note in plants the word variety is used but in animals the word breed is used. Nevertheless they are all different types ,brought about by mankinds interference by selecting the parent stock as against natural selection.
Of dogs, where nature selects , but while it is a good example of animal selective breeding ,ie look at the evidence of genetic modification through selective breeding by man.,when you note the vast difference in shape and size of the great dane and the chihuahua  , it is actually bad because all the dog breeds now have disease specific genes in their breed genomes ,brought about by mankind through his selective breeding methods ,using close incestuous matings to make a breed uniform and by carrying on up and down the line to grandparents/grandchildren and even parents  and across to siblings to maintain their uniformity.  But this brings together bad recessive genes ( double dose in offspring) ,which is very bad news.  So selective breeding can have many downsides and does have.  If it gets intensified the downsides get worse.

Almost every plant ( vegetables, flowers and so on ) that you see, buy, eat or whatever has been selectively bred, Which, in effect, means "manmade", through being genetically modified ,THROUGH artificial selection ,otherwise known as selective breeding.   You would have to go to great lengths to see a few wild flowers as they have also been killed off by mans indiscriminate usage of pesticides etc.  There,s  not much left that is natural anymore and it is getting worse each day.
