RETRACTED ARTICLE: Early Pioneers of the Americas: The Role of the Olmecs in Urban Education and Social Studies Curriculum

Abstract

The Editor-in-Chief has retracted this article (Wiggan et al 2020) following concerns raised by readers. After post-publication peer-review, it was found that the theory that Olmecs were Black Africans on which the lesson plan is based is not substantiated according to current Mesoamerican archaeology and genetic evidence.
