They are essentially the same; one simply uses the organismâs own natural genetic variation mechanisms, while the other introduces new variations manually. Yes, that is a difference that requires separation of the two in certain circumstances, but not when it comes to whether or not weâve genetically modified all strains of modern agricultural corn, GMO-labeled or not.
Claiming selective breeding is the same as producing a GMO is like saying an eagle and a Boeing 747 are both utilizing mechanisms that allow them to fly, which is true.

A bullet shot from a gun is not the same as a bullet moved a few inches every year.
We already know about the devastating effects of invasive species where an animal was introduced to a new environment and had unexpected effects.

Itâs the details that matter. It can take decades before side effects are noticed. Like DDT and now neonicotinoids. GMO could be better or worse. Saying itâs the same as natural selection is misleading which is why scientists use GM to mean direct gene modification, not natural or selective breeding.

Again, selective breeding suffers from the same issue of introducing changes that can be detrimental to the organism itself and its place in the balance of the environment. Look at dog breeding as an example. Pugs were bred for a specific look, and that inadvertently caused them to have severe breathing issues. Dachshunds are another example, with many developing spinal issues over time. The difference, as I said before, is the speed; making a change causes unintended side effects - when you make a huge change quickly, it will produce more side effects than making a small change slowly will.
And⌠again⌠as I already said⌠there should be limitations to prevent rolling out new GMOs without specific testing for safety, both in a lab for potential problems to the organism or - in the event of an agricultural product - its consumers, as well as in the environment as a whole, to determine how it may affect the ecology if and when it is introduced. It may take decades to notice changes if the GMO is released immediately after being developed, but if testing protocols are made and followed, we should have no problem quickly spotting any issues **before **the organism is rolled out into the world.
Just like newly developed medicines need to go through rigorous testing to prevent things like the Thalidomide scandal that caused an immense amount of birth defects due to lax testing, new GMOâs will need to be tested as well. But, just like you likely understand the benefits of medicine for helping people suffering from various diseases, GMOâs can provide the same level of benefit to people suffering from malnutrition, among a wide range of other positive uses. The key is to study new developments to the point where we can spot and address issues. Throwing away the technology as a whole is not the answer.
