AFTER YEARS OF SPIRITED debate over how and when people first reached the Americas, scientists finally seem poised to reach agreement. The emerging consensus: In contrast to what was long held as conventional wisdom, it now seems likely that the first Americans did not wait for ice sheets covering Canada to melt some 13,000 years ago, which would have allowed them to traipse south over solid ground. Instead, early nomads might well have traveled by boat or at least along the coast from Siberia to North America, perhaps navigating arctic waters near today's Bering Strait. The telltale evidence: ancient DNA from those early people that's been coaxed, by powerful analytical technology, into revealing its secret.

Most common opinion amongst scientists is that the first people in the americas arrived through the Barring Land Bridge that was connecting the Asian and North American continent during the last ice age. It is thought that these people were loving along the shores because the climate was milder and also they were able to have more opportunities in finding food from both land and sea.

What case overturned the Plessy case?

Goryan [66]

Plessy v. Ferguson (1896) was a Supreme Court case that affirmed the constitutionality of racial segregation so long as groups were provided facilities that are separate, but equal. This segregation extended from restaurants to water fountains to public schools. The case that overturned Plessy v. Ferguson was Brown v. Topeka Board of Education (1954). Brown v. Board ruled that racial segregation in public schools (and elsewhere) was unconstitutional on the basis that by virtue of making facilities separate, those facilities became inherently unequal.
