If any doubt remained, it was dispelled in 1994, when genetic analysis of the non-photosynthesizing euglenoid Astasia longa confirmed that this organism retains sequences of DNA inherited from an ancestor that must have had functioning chloroplasts.
Se quedaba algunha dúbida, esta foi despexada en 1994, cando as análises xenéticas do euglenoide non fotosintético Astasia longa confirmou que este organismo conservaba secuencias de ADN herdadas dun antepasado que debeu ter cloroplastos funcionais.
