I want you to arrange these balls into two or three groups based on likeness. please 1) list the ball numbers assigned to each grouping, 2) describe the reasoning behind each of your groupings (like a taxonomist), and 3) describe the difficulties in creating those groups. 1 In the lectures this week you learned about clinal variation. Blood type, genotype, nose form, hair color, eye color, skin color - traits that are driven by natural selection, genetic drift, and gene flow. 2 . 3 Below is a set of 13 hypothetical balls, arranged here based on the shade and circumference. But notice there is a third variable, the number of traverse lines. 4 For this assignment, I want you to arrange these balls into two or three groups based on likeness. please 1) list the ball numbers assigned to each grouping, 2) describe the reasoning behind each of your groupings (like a taxonomist), and 3) describe the difficulties in creating those groups. 5 6 . 7 This is purely an exercise in typological thinking and a simplistic example of clash between taxonomy and classification of clinal variation. There are no right or wrong answers. These are just three variables, imagine including the many other clinal biological traits among humans. And note that in this example, the attributes of size and shading co-vary. Imagine how much more variation would results from allowing them to vary independently, which is closer to the reality of humans. 8 9 10 11 12 13
