 science  keeps looking at evolution of bones. not evolution of human skills. some caves had people with painting aptitudes. other caves had people with tool making skills. caves with people who inherited the most aptitudes  became the dominate. body size was secondary. today, on average,  each Japanese person poses the most aptitude skills. so they stand on the top of the human evolution tree. so. stop looking at evolution of skulls. and form a family with grandparents of diverse aptitudes.
