Are Western Chimpanzees a New Species of Pan?

What if I told you there were populations of chimpanzees that made spears to hunt, lived in caves, and loved playing in water? These are behaviors usually associated with ancient humans, not chimpanzees. However, recent research has revealed that there are populations of western chimpanzees (Pan troglodytes verus) that engage in all of these behaviours, and it is challenging our current understanding of chimpanzee taxonomy. In other words, they may not be chimpanzees!

I have heard of chimps making spears to kill monkeys with and playing in water, they were just Chimpanzees.
