Judging only by skin color, most Korean hands would be indistinguishable from most Caucasian hands, and most Arabic hands would be indistinguishable from most Latino hands.
Likewise, judging only by brain function, no EEG-visible or MRI-visible differences appear between ethnic groups.
Brain volume is often calculated from MRIs, and varies between racial groups. (MRIs also give you brain volume of different regions of the brain, which also vary between racial groups.)
If you have any good (academic for preference) sources for the latter statement, I’d love to see them, mainly to add to my ‘Collection of X-refuting hyperlinks’ I have easily accessible when browsing the Internet At Large.
