Question
Part A-interpreting the graph This graph illustrates the relationship between average UV light intensity (where higher values mean more incident sunlight) and skin color (where lower reflectance values indicate darker skin) Points on the graph are color-coded to indicate the racial category of the populations measured Which of the labeled points (a-d) represents a population with the same skin color as the point circled in red, but is classified as belonging to a different race? Use the graph to answer the questions Race category of population: 80 Black Pacific Islander Native American Asian White 40 Submit Request Answer 20 400 100 200 300 UV light intensity (no units) Part B This question will be shown after you complete previous question(s) High Data from: Jablonski, N. and G. Chaplin, "The evolution of human skin coloration," Journal of Human Evolution,39: 57-106,Explanation / Answer
Labelled Point B represents a population with the same skin colour as the point circled in red, but is classified as belonging to a different race. Both the points share the same skin reflactance at 685 nm which means that they share the same skin colour. However, Point B unlike the circled point belongs to the race of Native American and not Black.
