Thinking human beings are naturally curious about the world around them, past and present. Moreover, discoveries like this can sometimes lead to practical applications.
YEARS ago, I read that some scientists were studying why Australian Aborigines didn't sweat and thought "oversupply of grant money". Then I read that NASA was concerned about keeping the astronauts from sweating too much or nor at all.
I now read these discoveries with a little less knee-jerk reaction.
You mean like Pit Bulls?
