both. caucasians were hunter-gatherers far longer than chinks. hunting, stealing meat, raiding caves and encampments bred stronger and bigger specimens thru evolution, which also meant weaker smaller ones died off in conflicts. chinks were farmers earlier, and farming and abundance of food spawned strong and weak alike but kept the small and weak alive to pass their physically inferior genes down. not only blood vessels, if you compare intestines or the gut, chinks have way longer intestines and longer torsos to hold them. this is because of thousands of years of digestive traits associated with processing grains in the gut. physiologically there’s a lot of difference between angmohs and chinks. even among the mongoloid races, mongols and siberians are different from chinks. they have larger bones and blood vessels.
