I think I first got this through a comic book (but I'm sure I looked it up). Horizontal evolution is when two organisms or groups of organisms who share a common ancestor but are otherwise different (geogrphically, usually), evolve a gene or behaviour at the same time. So for example if a monkey in Africa picks up a tool and a seperate breed develop the same way in India at the same time, this is horizontal evolution.
So, like, totally, like you know, how Japanese brands and, like, Scandy brands both, like started hyping raw denim.
