I thought I had read something that said there never was a genetic or even chemical difference between sativa and indica, just the terpenes are different. Like how there's all these different dog "breeds" but if you compare genetics they're like 99% the same.

Yeah, but the terpenes and cannabinoid profile is the whole point. Same way as dog breeds are quite different in size, fur, ear shape etc even if the genetic difference is <1%
Originally there was Ruderalis from Russia, Sativa from the (South?) Americas and Indica from India
Each with their own unique characteristics
But now Sativa and Indica have been crossbred so much practically everything is a hybrid, and it'd be extremely difficult to find original seeds from when they were separate. Except for Ruderalis, still very different, like with auto flowering instead of being seasonal
Nowadays stoners call energetic weed sativa, and sedating weed indica
