Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

We absolutely genetically modified pretty much all of our food. We just did it by selective breeding.
The only difference with modern GMO is we've learned to do it directly much faster. We don't need a random mutation to add a trait anymore.
Can we get a geneticist here?
Last time I was taught about biology, selective breeding was a process through which, over a long period of time, individuals with favorable traits were multiplied in order to increase the prevalence of such traits.
The genes were already introduced, hence, no modification. Already existing characteristics were allowed to further express and refine.
Genetic modification, to my understanding, implies introducing genetic information into the genome of an organism to produce another with traits previously completely absent in the species.
Selection vs manipulation.
I'll concede there are a few cases where the lines blurr, like the golden rice, where a gene that codified the production of vitamin A in the grain was/is already inactive or so receassive, in order to have it express again would require gene manipulation but I think a selective production program was put forward in an attempt to bring out that gene again.
Selective breeding is just one of the methods used to genetically modify our food.
I think you two have different images in your minds. You say "genetically modify" as in "modify the food through choosing which genes are to prevail", while the other means "modify genes directly to affect the food", and in that sense selective breeding isn't GMO because no genes have been modified, but rather encouraged. You modify the genetic structure of future generations through natural means, not the organism directly.
Don't know what scientists say, I just see the other comment downvoted when they have a fair point.
I can't agree with that.
The basic notion of genetically modifying an organism implies changes enacted at the genetic level, through artificial means, not biological.
