human
is it possible that an ancestor of a species has more or less chromosomes?

I was wondering about how the amount of chromosomes were affected by evolution. Like is it possible that one ancestor has more chromosomes or less chromosomes?

So basically: how does the amount of chromosomes correlate to evolution?

Yes. Humans have 23 pairs of chromosomes while apes have 24. Researchers examining the gene sequence of each types have determined that at some point during the course of evolution, two pairs from our common ancestors have fused into one in the human lineage. The gene sequences of one human chromosome appears to match the sequences found in separate pairs for the ape genome.
