What kind of se am I? Does anyone have some tips in identify ing how se is being used in a sentence, specifically between reflexive se and passive se. I encountered a sentence..'Relativamente aislados, los grupos se evolucionaron y se adaptaron a los diferentes lugares." I was assuming this was an example of reflexive se. Translated as.."the group adapted (themselves,) and evolved ( themselves?)...but I'm not sure. Just a few lines later, another sentence reads..." Miles de anos despues Las migraciones y Las tecnologias de transported Han hecho que algunos rasgos que evolucionaron.."( note the absence of se) Or could it be a passive use, , but that doesn't seem to be right either..., As " los grupos" is Clearly the subject.. I apologise for the lack of diacritic markings
