Where does ditto come from?

We all know this pinkish piece of jelly, slop, ....squishy.... thing


whoops wrong photo here a clearer version:


We all have hunted down this majestical species in hopes of whoring breeding our slutty beloved pokemon to create the perfect fighting machine....or just to make a lot of grandchildren who knows what you do...

This being has tormented us by not going into the pokeball sometimes unless you use a rattata.....

It has a deep desire to change into what its not


My question is where do these guys come from?
Perhaps the Rocket Labs where they tried to clone mew another pink slop?
Mew's shit poopy?

PS there was no need for any of you to read all that the question is in the topic
PSS if you read this in your head you are temporarily an idiot

hm....ditto is mew's poop...never thought of it like that hahahhahaha
Makes sense though because mew is the "Eve" of all pokemon. Although, i would like to think that he is like the white blood cells or something of the like..
Maybe pokemon needed to breed, so nature was all like yoh dawg we'll have a pokemon that will be all pokemon! Thus, ditto was created
