So for at least half of my life now I have tried to life by the idea that I should learn something new everyday. It doesn't have to be anything significant. Maybe it's just some new vocabulary, Maybe it's some new scientific theory that explains the universe. What ever it is the important thing is to try to learn something new, to never stop learning from the world around me. And with the infinite expanses of the Internet to be pulling information from it shouldn't be too hard to learn something new most days.
Today I was reading some articles about genetic evolution. One of the things I learned is that many people involved with researching human evolution are, for lack of a better word, afraid to think there might actually be genetic evolutionary differences between the "races" of humans beyond the obvious skin deep differences. And why are they afraid? Because it might hurt the feelings of people from ethnic groups that have historically been treated as inferior and supposed biologically scientific "facts" used to support said treatment.
I have heard for most of my life that Africans are better runners because they have an extra tendon in their ankles or some such thing. I have no idea if this is true or not and don't really care to look it up but if its true that would definitely seem to indicate some sort of genetic evolutionary change to set them aside from people that don't have that tendon. Does that make them superior or inferior in any way? Well at most it seems to make them superior runners.
So why are scientists afraid to study a subject just because it might hurt some feelings? Every new discovery has the potential to hurt some one's feelings. If we stopped all actions that might hurt some one's feelings we would never get anything done.
I say let scientists study whatever theories they want and when they come back with proof of one idea over another its the job of society as a whole to learn from it and interpret what that means for that society.
