This became a way of creating domestic plants and animals that could be cultivated or controlled.
The new species can survive in places and under conditions that the parents could not. Modern day wheat was created this way, people began to live in cities and the original plant didn’t yield enough to feed large populations. This plant was crossed with another and the end product yielded lots of grain. This new plant was also bred so they could resist certain pests and could be planted all in most climates over the world.
The original grain that it was made from was not high in starch. By changing the genetic order the new plant is high in starch, which is corrosive to human tissues.
There are many people who are allergic to wheat and are not aware of these facts. Changing the genetic order of wild plant or animal can create genetic mineral and chemical imbalances. Therefore change mutations of cell of any living organism that consume that eats it.
