The source does not claim Brazilian Gauchos are descended from people from the city of Laguna. It only says ""people from Laguna organized the creation and trade in livestock"". Moreover, Darcy Ribeiro claim that ""The Brazilian Gauchos have a common historical formation with the other Gauchos from the Plate. They arise from the ethnic transformation of the mixed-race people of mixed Spanish and Portuguese men with Guarani women"".

The population from Southwest Rio Grande do Sul is largely connect to the old population from Argentina and Uruguay, before the mass European immigration in the late 19th century that actually changed most of the ethnic formation of Argentina and Uruguay. Since Southwest Rio Grande was not affected by the more recent European immigration, the population there still has the same Portuguese/Spanish/Guarani origin of the Gauchos from La Plata Basin. It seems the text there is ignoring the Guarani Indians in the formation of the people in Rio Grande do Sul, particularly Southern and Southweastern Rio Grande, wich was very important and undeniable.
