For example, for the first time, a few years ago, by simply collecting little fecal samples we were able to have them analyzed -- to have DNA profiling done -- so for the first time, we actually know which male chimps are the fathers of each individual infant.
Por exemplo, há poucos anos, pela primeira vez, com a simples coleta de amostras de fezes, fomos capazes de analisar - de determinar o DNA - e pela primeira vez pudemos realmente saber quais machos eram os pais de cada bebê chimpanzé.
