Why would I deny the possibility of reptilian humans? I'm not saying they exist. I'm saying I don't know. So, you cannot talk about what you don't know. Genealogy is interesting to study. We can see different countries and cultures in Asia. Part of that is due to intermarriages between black people, Asians, white people, etc. Also, the differences between Chinese, Japanese, Vietnamese, Koreans, etc, can be due to the genetics as well. Like, DNA will make children look a little different than their parents. Over time, differences can change from generation to generation. Darker skinned Asians are probably part black because they breed with black people in the past and/or due to genetic probabilities from generation to generation.
