Option 3: Sweatt struck down “separate but equal” graduate and professional schools. Brown struck down “separate but equal” public schools.

Explanation:

The Sweatt v. Painter (1946) struck down “separate but equal” graduate and professional schools. More specifically, the case established that Sweatt, a black man who had applied for admission to the University of Texas Law School and had been rejected, should be admitted to the University, basing on the Equal Protection Clause. The Court held that the other University for black people "law school for Negroes," which the University would have opened the following year, would have been totally unequal to the University of Texas Law School, in terms of quality, facilities, and opportunities.

As for the Brown v. Board of Education case (1954), it struck down “separate but equal” public schools as the Supreme Court determined that racial segregation of children in public schools was unconstitutional, because “separate but equal” facilities were, in fact, unequal and considered a form of discrimination that instilled a sense of inferiority to African Americans children and thus it violated the 14th Amendment.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
