Science - ask a geneticist

Reading the articles in the links provided I learned many different things, including humans have 46 chromosomes and chimpanzee's have 48. This is because species that are similar have similar amounts of chromosomes, chimpanzee's have more because, upon looking at the model you can see, for a couple of the chromosomes two chimp chromosomes made up one of ours. This means as we evolved some of ours melded together and we only have 46 chromosomes. And that is one of the many things i learned from these articles.
