If two identical Earths had been created at the same time, would life have evolved differently on Earth B?

Question

The other earth would be the same distance from the sun as this one is and have identical conditions . . .

Answer 1

Maybe this IS earth B.

Gasp!!!!

Answer 2

It all depends on the distance from the two Earths. If they were close to another like the moon is to us, (app. 480,000 miles) there could be identical forms of plant life, but not all of which we have now.The reason being, is that the other Earth would cast a larger shadow during an eclipse. Also, the tides would be adversely affected causing extreme low and high tides.

As for mankind, there would be all out war of one civilization trying to conquer the other. Case in point, look at what is going on now on the one Earth.

If another Earth were light years away it would need another sun at about the same distance that we are from our sun (app. 90,000000 miles)  to have the same forms of life.

Answer 3

probably not - a big part of our planets development came from ice asteroids crashing into it, which in turn gave us the oceans and the atmosphere.  If these 2 earth's did not occupy exactly the same space, then the probablility of the exact asteroid impacts on both is nearly impossible... and it is these interactions that gave us water... and just the right amount for life (cool question!)

Answer 4

If life evolved, then it would evolve differently but in a similar fashion since the same materials and amount of them would be contained on that other Earth.

You'd have similar lifeforms, albeit not the same lifeforms, and likely they would not be able to reproduce with the lifeforms of the other Earth.

Answer 5

yes, if everything is equal
