A while back I was watching Rise of the Planet of the Apes and I started thinking, "What would that look like?"
Due to mass extinction in the distant past, primates became the largest, most dominant animals on the planet. This one has evolved into a role similar to the Asian elephant.
Rather than large ears, it possesses a dewlap for heat regulation.
Its front limbs retain their knuckle walking stance. Four of its digits are fused together and have a cushion of fat to aid in support.
