We all know gorilla and black have genetic connection. There is an interesting thing that gorilla and black have a close relative called Maori. Maori may not look that black, and they even know how to use simple tools; like apemen. There is a scientific evidence shows that Gorilla may be Maori's ancestor.
A Maori History teacher asking students: "Who are our ancestors". Students reply in chorus, "Gorillas"
"Yes, we're gorilla's close relative"
