Dogs, "Bad breed"

I was wondering if there is any biological fact that breeds like lets say Pit Bull or Rottweiler are prone to violence. Also. I was once told that the reason that pit bulls become violent is because there brain gets too large for there skull and as a result of the pressure created they become violen...

Lately I'v been hearing alot about "lean muscle mass" helping in weight loss. What exactaly is "lean muscle", is it different from normal muscle?

Theres tons of talk about it but no body really explains what it is!

as far as I know, it isn't. Considering that the contraction and relaxation of the iris is a reaction to stimulation so if the brain doesn't receive the stimuli (like in blindness) it wont send a message back instructing the iris to contract or relax there's alot of diffrent types of blindness thoug...

No I didn't know that but now I do, thank you.

Almost all of my knowloge lies in physics, so I'm here to learn.

yes, this I already know and yeah it is only in retro-viruses.

I just thought it was interesting that it only evolved in retro-viruses. Another thing I thought was interesting was what enviromental conditions could have prompted that evolution?

Yes... the "normal" (whatever normal is) human eye can only see a VERY small part of the electromagnetic spectrum

I was just wondering if it is at all possible for the naked human eye to see beyond the regular visual range

Reverse transcriptase in non-viral creatures

considering that DNA is madeup of base pares all that is really needed to determine its makeup is a simple peice of single helixed RNA (with the help of reverse transcriptase) so why have all "liveing" things based them selfs upon DNA and only use RNA as messenger protines some how I doubt there is ...

Evolution of the eyes

Is it possible for the naked human eye to see (through some sort of genetic mutation maybe?) beyond the normal visual Em spectrum, even if in the slightest?
