explain two theories that explain about the origin of man

Answers

Answer 1

Answer:

There are two main theories The Out-Of-Africa theory and The Multiregional, I'll try to explain both of them as best as I can.

They both agree that Homo erectus originated in Africa and then expanded to Eurasia about one million years ago, but then differ on where the modern human originated from

The Out-Of-Africa theory:

It states that a second immigration out of Africa happened about 100,000 years ago, through this immigration it is said that anatomically modern humans of Africa overtook and conquered the world completely replacing archaic human populations.

The Multiregional theory:

It states that there were multiple independent origins OR there was a multiregional evolution with gene flow between different continental populations. This happening over the million years after Homo erectus came out of Africa.

bonus

The Trellis theory:

It is basically a compromised version of the Out-of-Africa theory but, emphasizes the African origin of most human populations but allows for the possibility of minor local contributions.

Hope this helps! :}

Washington's international dealings

Answers

Answer:

Washington counseled the public to be wary of foreign influence. He argued for impartial commercial treaties, but against treaties of permanent alliance, although the United States should fulfill any existing agreements "with perfect good faith." Temporary alliances would be acceptable in "extraordinary emergencies."

Washington's foreign policy focused on protecting the independence of the new nation and avoiding expensive and deadly wars. During Washington's first term, European powers sought every opportunity to undermine American sovereignty.

In the fall of 1796, nearing the end of his term, George Washington published a farewell address, intended to serve as a guide to future statecraft for the American public and his successors in office. Washington worked closely with Alexander Hamilton, Secretary of the Treasury, and James Madison, then a Congressional leader, who both provided Washington with drafts of the address. Washington’s address argued for a careful foreign policy of friendly neutrality that would avoid creating implacable enemies or international friendships of dubious value, nor entangle the United States in foreign alliances.

Washington had initially considered retiring from the presidency after his first term in office. Therefore, in 1792, he asked James Madison to compose a valedictory address to be delivered at the end of the first term. However, Washington was persuaded by Hamilton, former Secretary of State Edmund Randolph, and other political leaders to remain in office for a second term, and so the draft remained unused. When Washington neared the completion of his second term, he turned to Alexander Hamilton to edit Madison’s draft. Hamilton enlarged the portion relating to foreign affairs, and updated it to reflect the Washington Administration’s revised neutrality policy. Washington then amended Hamilton’s version, and also asked Secretary of State Timothy Pickering for his opinions on the address. Washington then arranged for the address to be published in a Claypool’s American Daily Advertiser, a Philadelphia newspaper, on September 19, 1796. The address was widely reprinted in newspapers throughout the country.

Although the address also dealt with domestic issues, Washington was also interested in outlining future U.S. foreign policy. Washington expressed his views on foreign relations with a warning against "permanent inveterate antipathies against particular Nations," as well as "a passionate attachment of one Nation for another." The first, he argued, would lead to an unnecessary war, while the second would result in unwise treaty concessions, which could arouse the ill-will of other countries expecting fair treatment. Washington counseled the public to be wary of foreign influence. He argued for impartial commercial treaties, but against treaties of permanent alliance, although the United States should fulfill any existing agreements "with perfect good faith." Temporary alliances would be acceptable in "extraordinary emergencies."

Which of these is MOST responsible for the end of the Reconstruction Era?
A. The Civil War
B) Jim Crow laws not this one
C) Election of 1876
D) President Ulysses S. Grant

Answers

Answer:

C) Election of 1876. I think

Explanation:

The Election of 1876 is most responsible for the end of the Reconstruction Era. The election was a highly contested and controversial one, with competing claims of electoral fraud and voter suppression. The correct option is C.

What was the main purpose of the reconstruction era?

From 1865, when the Civil War came to a conclusion, until 1877, was known as the Reconstruction Era. Its primary objectives included restoring the southern states' full political involvement in the Union, securing the rights of former slaves, and establishing new interactions between African Americans and whites.

The Republican candidate, Rutherford B. Hayes, eventually emerged as the winner, but only after a compromise was reached in which Hayes agreed to withdraw federal troops from the South and end Reconstruction in exchange for the Democrats agreeing to recognize his presidency.

This compromise effectively marked the end of Reconstruction, as the withdrawal of federal troops from the South meant that the Republican Party could no longer enforce the civil rights laws and protections that had been put in place during the Reconstruction Era.

Thus, the ideal selection is option C.
