 :::This picture is an improvement but I agree with Chrisrus and others questioning whether these pictures of a white 'couple' are close to the ideal. In an article on anatomy, there is no need to be restricted to pictures of a couple (a social concept); given that the aim is to improve accuracy, an image where pubic hair is not shown and the woman is standing with a slightly odd posture are also shortcomings since these are not typical of the human anatomy; the fact that they both appear white is particularly inaccurate when the image is to be used (as suggested) in an article about human evolution. In this case, the idea of excessive political correctness appears to have been used (as it often is) to defeat valid points rather than invalid ones.  
 :::There are several possible solutions, none ideal but all improvements. First, choose different races and body types for the two sexes and label them so as to make it clear that there is variation (eg "Older Caucasian male", "Small body type, African female"). Second, use an outline/sketch rather than a photograph of models to convey the idea that these are generalities. Third, show three variations of both male and female and label them to emphasize the variety of shapes of the human body.  19:04, 6 January 2012
