Yes, but you don't need other human beings who can't fly to use as an example. You can simply realize that not flying would be evolutionarily disadvantageous.
I know what you mean dude. It would be considered normal to us, just like walking is right now. I'm against having everything "perfect". If everything was perfect we wouldn't even care, we would be machines.
I forgot where I heard this, but there was two people having a conversation.
Person one: everybody's special.
Second person: that's just another way to say nobody's special.
I think everyone being perfect is just another way of saying nobody is perfect. I believe people are more perfect now then they will be years and years from now. Right now, everyone has their own special qualities that others don't have, and that's what makes them perfect.
But I do see your point, and I agree with you. Evolution is in our favor. I'm just saying it would suck if everyone was "perfect".
Ehh I have a bunch of random thoughts right now, so sorry if this is way off topic, lol. >>>Morals, usually with morals there's good and bad. What makes something bad and what makes something good? I think you have to have one or the other to make something good or bad. If not then everything would seem normal, not good nor bad.
