coz i cant find that questions of the universe thread. can a mod move this and attach it to it if its not too much trouble (sorry!) the question i thought of today and would like answering is: u kno how we all got 2 parents. 4 grandparents. 8 great-grandparents. 16 great-great-grandparents. etc, etc, etc. so in theory the further back u go, the more people were needed just to make ONE person living in 2007? so, if it took, say 10,000 anscestors to make each person living today, how is it that the population is bigger NOW? this really puzzles me! sorry if its already been asked, i couldnt find the thread to check.
