Ethiopians And Middle Easterns Are The Same???????????????

I think you're making several mistakes here.

1. You're confusing similarity in appearance with kinship. That's the same fallacy that made people think porpoises were fish. Peoples in hot climates tend to evolve dark skin to avoid melanoma and peoples in colder climates tend to evolve light skin to get more vitamin A. They're survival traits. Native Americans in southern Quebec and Venezuela are closely related. People in the African desert and the Australian desert are not.

2. You're confusing culture with genetic ancestry. There were only six original ancient civilizations: Aztec/Maya/Olmec, Inca, Egypt, Mesopotamia, India, China. The first three were destroyed by invaders. All other civilizations on earth are composites of the other three with a few bits and pieces of the lost ones. Since the invention of rapid and affordable travel and communication in the last couple of centuries, trading of cultural motifs has become so common that it's difficult to tell where one civilization stops and the next one begins. People in Beijing watch MTV and people in New York eat chow mein.

3. You're assuming that there are clear boundaries between the "so-called races." These boundaries already began to blur during the time of the ancient civilizations. Persians, Greeks, Egyptians, Hebrews and Arabs intermarried and/or took each other as slaves and had non-consensual sex. Sub-Saharan Africans and the Turkic-Mongol people joined in the mix voluntarily or not. The Chinese and the Indians did the same thing in their spheres of influence, as did just about everybody when they found their way to the Americas. Surely you've met a few people of your own "race" who look like their great-grandfather was from halfway around the world, and perhaps he was, or perhaps it was his great-grandfather.

Notwithstanding all that, sub-Saharan Africa, western Europe, India, China and its neighbors, pre-European-occupation Australia, and the pre-Columbian Western Hemisphere south of the Rio Grande had relatively distinct gene pools until that fast cheap travel began to blend them in recent centuries. The Mideast and North Africa were already pretty stirred up by first the Arab and then the Ottoman conquest, and eastern Europe was already a DNA smorgasbord.

The Ethiopians you speak of are all that's left of the Cushitic people whose most famous nation was ancient Egypt, but they've heavily intermarried with the Arabs who totally displaced the Egyptians from their own country. The Arabs themselves have spent centuries mingling in a community that includes Persians--and Turks, who themselves were originally Mongols who stopped and married everyone they met on their long journey. The people of southeast Asia and Oceania have as rich a background as any of these other people: Chinese, Indian, Polynesian, and more recently European, their roots run in many directions.

But today, with tiny, rare, remote exceptions like New Guinea, the Arctic, and the deepest reaches of the Amazon basin, we've done a pretty good job of stirring the Melting Pot. We're all just people.
