Hey, I recently watched a video on YouTube by Kenneth Miller, The collapse of Intelligent Design. One of the things he brought up in the lecture was a comparison between. Human and chimpanzee genome. What was specifically said was that we had 23 pairs of chromosomes while the chimp and all other apes had 24. What must have happened is that over the course of our evolution, two chromosomes in our common ancestors with the chimp must have fused. This was found to be the case, our chromosome #2 is this fused chromosome. What puzzles me is that before this mutation spread throughout the population that lead to us, it must have occurred in one individual to start. Now we get half our chromosomes from mum and half from dad. How did this Individual with 23 pairs reproduce given that everyone else in the population had 24? From what I remember from bio class, the chromosomes need to pair up. So how did this produce a viable offspring? What am I missing? Thanks.
