Este artigo apresenta uma revisão de algumas questões metodológicas no uso de datas radiocarbônicas para reconstrução de episódios de dispersão humana registrados arqueologicamente. Estudos sobre este tema têm investido em estimar ritmos e direções da expansão espacial de populações. Uma aplicação apropriada para estas técnicas é o povoamento inicial das Américas. Discutimos neste artigo técnicas de regressão para estimar ritmos de frentes de deslocamento e salientamos algumas limitações decorrentes de uma amostragem arqueologica incompleta e de datações radiocarbônicas imprecisas. Apresentamos também resumidamente resultados de um programa recente de datação de sítios previamente escavados na Argentina e no Chile.
