What is chromosomal evidence for common ancestry of apes and man?

Chromosomal evidence for the common ancestry of apes and humans primarily comes from the comparison of chromosome structures and numbers. Humans have 46 chromosomes, while great apes, such as chimpanzees and gorillas, have 48. This difference is attributed to the fusion of two ancestral ape chromosomes, which is evidenced by the presence of a fused telomere and centromere on human chromosome 2. Additionally, the similarities in chromosome banding patterns and gene sequences further support the close genetic relationship between these species, indicating a shared evolutionary history.
