Why haven't we built small robot's (minning machines) and sent them into the asteroids to harvest the ore there and then use it to make objects for consumption on earth, or to make more robot's to mine more asteriods?

First off, i apologise if this is in the wrong place... I really dont see where i'd put it..

Secondly, I kinda have two questions, the title is my main question, the one below is a hypothetical situation im just sort of curious on. =D thanks.

How to word this...

Natural selection is a process that weeds out "weak" individuals and allows room for the stronger ones. What would happen to a species if Natural selection were eliminated. (No food/water shortages, no unbalanced gender populations, no natural enemies and no diseases, as much room as they could possibly need)

Would the "good genes" that helped their survival still be predominate after so many years? Would mutations become a problem? How would evolution effect them after millions of years, living in a "near-perfect" environment?

There are inconsistencies about the number of continents. Some people say 5 others 6 or even 7.

I think a continent is consider a solid mass of land so why some sites refer America as North and South America. What about Antartica? it is consider a continent.

Thank you in advance

A bag has an unknown number of colored objects, with equal numbers of each color. Adding 20 objects of a new color to the bag would not change the probability of drawing (without replacement) two objects of the same color.

How many objects are in the bag? (Before the extra objects are added.)
