How was it possible for Neanderthal Man and Homo Sapiens to evolve as separate species?

History

Geographic isolation and different living conditions.

Explanation:

Both the Neanderthal and the Homo sapiens shared the same ancestor, the Homo erectus. The Homo erectus managed to spread from Africa to Eurasia. The populations started to become geographically isolated from each other, and over time this caused speciation.

The Homo erectus from the far East, with the one from Europe, or the one from Africa, didn't had contact. This was due to big distance and natural barriers. Gradually this species was evolving, and because of the different living conditions and the geographic isolation at different places it started to develop different characteristics. This has led to evolution of different species over time, with the Neanderthal evolving in Eurasia, as well as the Denisovan Man, while in Africa it was the Homo sapiens that emerged.

How much did the average loaf of bread cost in 1912 in u.s.?
TiliK225 [7]
About a nickel.

The oldest statistical data I can locate doesn't have information earlier than 1913, but in 1913 the average loaf of bread was shown at 5.6 cents.  This was as reported in <em>Historical Statistics of the United States: Colonial Times to 1970 (volume 2),</em> as published by the <span>U.S. Department of Commerce.</span>

 Or, as another example, the Denver post reported that in 1912 Hurlbut's--which was then a grocery store in Denver--advertised "<span>six loaves of 'homemade' bread for 25 cents," which would work out as a special price less than 5 cents per loaf for the store's bakery bread.   (Source:  "A Titanic Difference in the Cost of Living 100 Years Later, <em>The Denver Post, </em>March 16, 2012.)</span>

Why did the American economy collapse in 1929? Explain the role of the primary factors, and be sure to note the role of governme
ASHA 777 [7]
The Great Depression was a period of unprecedented decline in economic activity. It is generally agreed to have occurred between 1929 and 1939. Although parts of the economy had begun to recover by 1936, high unemployment persisted until the Second World War.
<span>The 1920s witnessed an economic boom in the US (typified by Ford Motor cars, which made a car within the grasp of ordinary workers for the first time). Industrial output expanded very rapidly. Sales were often promoted through buying on credit. However, by early 1929, the steam had gone out of the economy and output was beginning to fall.The stock market had boomed to record levels. Price to earning ratios were above historical averages.The US Agricultural sector had been in recession for many more years<span>The UK economy had been experiencing deflation and high unemployment for much of the 1920s. This was mainly due to the cost of the first world war and attempting to rejoin the Gold standard at a pre world war 1 rate. This meant Sterling was overvalued causing lower exports and slower growth. The US tried to help the UK stay in the gold standard. That meant inflating the US economy, which contributed to the credit boom of the 1920s. 
</span></span>During September and October a few firms posted disappointing results causing share prices to fall. On October 28th (Black Monday), the decline in prices turned into a crash has share prices fell 13%. Panic spread throughout the stock exchange as people sought to unload their shares. On Tuesday there was another collapse in prices known as 'Black Tuesday'. Although shares recovered a little in 1930, confidence had evaporated and problems spread to the rest of the financial system. Share prices would fall even more in 1932 as the depression deepened. By 1932, The stock market fell 89% from its September 1929 peak. It was at a level not seen since the nineteenth century.
<span>Falling share prices caused a collapse in confidence and consumer wealth. Spending fell and the decline in confidence precipitated a desire for savers to withdraw money from their banks.</span>
