    Images of human evolution in South African life sciences textbooks
    (2017) Nyagwaya, Martin
    Images in human evolution play a pivotal role in helping learners understand the nature and characteristics of early humans which are central to understanding human ancestry and identity. These images, like any sign systems, were created from a particular perspective and are prone to have multiple interpretations depending on the ideological and cultural disposition of both the creator and the reader. Therefore, there is a potential that unintended meanings and associations with the representations could propagate misconceptions about human evolution. This study aims to investigate how Grade 12 Life Sciences textbooks portray human evolution through the use of a semiotic analysis based on Barthes’ (1977) semiotic theory. Through conducting my analysis, I found out that multiple modes of representation were used to portray human evolution. I also found that the degree of accuracy varied with graphs being the most accurate in comparison to other modes of representations. Furthermore, some images latently communicate race and gender related biases as well as the idea that apes are ancestors of human beings. The implications of this study are that there is need to make Life Sciences teachers more aware of the multiple meanings associated with images of human evolution so that they can articulate the multiple meanings of these images. Furthermore, there is a need for further study regarding how teachers and learners interpret the meanings associated with human evolution images with an aim of revising them if need be so as to enhance learning of the relevant concepts about the broader concept of human evolution.
