Genetic modification of food is not new.

GMOs, or “genetically modified organisms,” are plants or animals that have been genetically engineered with DNA from bacteria, viruses or other plants and animals.

For centuries, food crops and animals have been altered through selective breeding. While genes can be transferred during selective breeding, the scope for exchanging genetic material is much wider using genetic engineering. In theory, genetic engineering allows genetic material to be transferred between any organism, including between plants and animals. For example, the gene from a fish that lives in very cold seas has been inserted into a strawberry, allowing the fruit to be frost-tolerant.

By far the most common genetically modified (GM) organisms are crop plants. But the technology has now been applied to almost all forms of life, from pets that glow under UV light to bacteria which form HIV blocking "living condoms" and from pigs bearing spinach genes to goats that produce spider silk.

These experimental combinations of genes from different species cannot occur in nature or in traditional crossbreeding.
