It's from the first generation of Pokemon. The egg mechanic came with the second generation.
The first generation even mentions South America, real world references weren't a thing in later generations either.

It make sense when you admit that pokemon is a post-apocalyptic universe

The world was build on the ashes of our and a few references still exist

These bioengeenered monsters probably ended the wars and are now roaming arround but we still remember what was a mouse and some nerd ad the line in the pokedex to make fun of pikachus

Do you remember where they mention South America? Game or anime? Thanks in advance!

Game. It's in the Pokemon Mansion on Cinnabar Island. They found Mew in the South American jungle.
Also Major Surge is called an American IIRC and a war he fought in is alos mentioned.

There's an old man in Surge's gym who says he served with Surge in the war iirc.

Mythical pokemon can't lay eggs so it makes sense that live birth is the method by which they propogate.
