4. what consequences can the migration of people today have because of skin pigmentation? 5.  why do you think human societies have given social meanings to differences in skin pigmentation (i. e., why do you think we separate people into "races" based on this factor)?

4) The consequence is you won’t be able to enter if you’re a certain color. Because there’s people today who assume races and are racist, they won’t let people in. For example, after trumps speech, if you have a Mexican skin looking pigment, you’ll get stopped and maybe checked. If you look like you’re from the Middle East, they may stop you because they may think you’re a terrorist, et.c.
5) I think we separate races because we think our own race is more dominant. For example, the kkk thinks that white races are better because they’re more dominant.
