1. How was Roosevelt's 1907 statement on immigrants considered progressive for its time? 2. Explain how you feel about the validity of his statement in our current time.

1. Roosevelts statement on immigrants was considered vastly progressive for the time, as people had been discriminating against people based on birthplace for years. That wasn't the kind of change in people you would expect to see overnight, but he pushed for it anyway.

2. I feel like this statement is very much valid, if not underperforming. It doesn't matter where you come from, or what your country of origin was like, all that matters is you're here not and how you act now. Not hiring somebody because of where they are from will only windup as a huge loss for your business,

the answer might be either a or c. can't be too sure , because i searched the web, but no valid answers came through.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
