Subspecies derived from wild ancestors through artificial selection.
There are many subspecies of plants and animals that have been selectively bred by humans.
Without human intervention, these subspecies would not exist. The only species that would exist would be their wild ancestors.
Some examples are:
They have been the result of artificial selection for hundreds or thousands of years. Humans have selected them for certain features that survive in future generations or selected for variants that appear due to mutations during the domestication process.
Tasteless Thanksgiving turkeys are the result of selecting those with the largest breasts, so large that males can no longer mount females and need to be artificially inseminated.
The ears of corn we eat are the result of selecting a grass called Teosinte that today would go entirely unnoticed.
The ancestral tomato weighed no more than a few grams.
Wild bananas (Musa balbisiana) are not edible because of the amount of seeds they contain.
The wild mustard plant was artificially selected in many different ways and gave rise to broccoli, domestic cabbage, kohlrabi, kale, Brussels sprouts and cauliflower.
All grains are the result of the domestication of wild subspecies over the past 12,000 years.
