Question:
How can sexually reproducing organisms (e.g. primates) with different chromosome numbers have a common ancestor?



Replies:
Sometimes two chromosomes fuse together to make one. This is what appears to have happened to make the human number from an earlier primate ancestor. Some primates can tolerate odd numbers more than others.
