It's all about adapting to your environment. Really bright and hot in Africa = Darker tone to protect skin more Europeans turned white because of inadequate UV radiation in northern latitudes and something about vitamin D (look it up). Lots of Asian ethnic groups have something called an epicanthic fold (asian eye) which might have been an adaption to protect the eyes in colder environments in Asia.
6,600 years ago a rogue black scientist named Yakub created the white race in a laboratory. Little did he know that 5,000 years later his little creation would turn out to be the great oppressor. Yakub also known as John the Revelator/Divine is frequently cited as the author of the Book of Revelation in the Christian Bible.
I never use Hispanic, Latino, or Asian just because they are not specific enough to anything to be useful to me.
Asian refers to several different countries. Race and nationality are two different things. Most people in Europe can be considered white, yet they all look differently and are from different countries speaking different languages. the third guy in the picture you showed is obviously from asian decent or indiginous, in which case I believe he would fall under a different race all together. Hispanic works for me. latino not so much.
Im Mexican - American or Chicano. My parents were born in Mexico and I was born in the United States.
