What if recombination never happened?

What if Neanderthals would still be around, instead of us, supposedly Cro-Magnon's descendents?

What if you were on a plane at LAX, left the ground, and then there was a MAJOR earthquake.

What might happen to the crew and passengers. Maybe ground and other air traffic controllers would be down. What would people see from the plane and how would the flight continue? What would the pilot do? Is there already a contingency plan for this?

Sincerely,

gloom and doom - no, really.

You know what the world would be like without us? Bo-ring!

In the chronicles of Gilgamesh it talks about Adam and Eve, in the bible it talks about Adam and Eve. Since we consider Cro-Magnum's as the first real humans, would that make Adam and Eve Cro-Magnum, considering the bible said that they were the first humans to inhabit the Earth, or do you think that Adam and Eve go back further then that? Just wandering, because we say that man started in Africa, but the garden of Eden is supposed to be in the middle east ( the last show i watched had evidence that supported that idea ) and if I'm not mistaken wasn't the middle east the starting point for Cro-Magnum? I know there is no concrete evidence to say that it is true, I'm looking for a scientist point of view not a preachers or friends.


thank you

Is it possible if all the ice melts at both poles, and all the oceons rise as predicted,will our planet pivot and start another ice age?? If so ,has it happened before?
