From ScienceDaily:

“Surprisingly, we found that in many ways the gorilla Y chromosome is more similar to the human Y chromosome than either is to the chimpanzee Y chromosome,” said Kateryna Makova, the Francis R. and Helen M. Pentz Professor of Science at Penn State and one of two corresponding authors of the paper. “In regions of the chromosome where we can align all three species, the sequence similarity fits with what we know about the evolutionary relationships among the species — humans are more closely related to chimpanzees. However, the chimpanzee Y chromosome appears to have undergone more changes in the number of genes and contains a different amount of repetitive elements compared to the human or gorilla. Moreover, a greater proportion of the gorilla Y sequences can be aligned to the human than to the chimpanzee Y chromosome.”More.

Paper is open access.

    Humans are a lot older than gorilla. Did gorilla descend from human?
