And if anyone has did they ever try breathing without masks? I know this question probably sounds like a joke but I'm serious. I look at the pictures of Mars and it looks so much like just an ordinary desert with blue sky in the background. I know about the zero gravity thing but am just not completely aware of the reasons they say you cannot breath. Thank You.

I understand that if there is enough genetic mutation, a new species is created because it can no longer reproduce with the parent species. What are the mechanics of this? Thanks

If a=1 and b=1 then a = b
Multiply by a* then a* = ab
Subtract b* then a* - b* = ab - b*
Factor then (a + b)(a - b) = b(a - b)
Divide by (a - b) then (a + b) = b
Then 1 + 1 = 1
Then 2 = 1
