One item that has caught little interest is when and why and with
consequences two chromosomes have merged in Homo, so that we have 23
pairs, when the chimpanzees have preserved the 24 chromosome pairs. How
many chromosomes did the Australopithecines have? Was this mutation the
key to the great variety of Australopithecines and was it the key leading
to Homo?

I know that nobody knows, but one can always speculate based on the
changes occurred during the time.
