Mary Douglas Leakey was recognized in her lifetime as one of the world’s most distinguished fossil hunters. In 1974 Mary BEGINS work at Laetoli, 30 miles from Olduvai Gorge. It is here that Mary and her team found amazingly well preserved hominid footprints in volcanic beds, known as tuffs. The footprint tuff of 1976 has a potassium argon date of 3.5-3.8 mya, evidence of upright walking that supported Donald Johansen's find, Lucy, also known as Australopithecus Afarensis, though Mary Leakey has rejected this( she believe that the belong to the genus homo). Eighty feet of trail had been uncovered by 1979, leaving researchers to speculate that it was three hominids, possibly a family, that left their mark millions of years ago.
1929
The Great Depression was the worst economic downturn in US history. It began in 1929 and did not abate until the end of the 1930s. The stock market crash of October 1929 signaled the beginning of the Great Depression. By 1933, unemployment was at 25 percent and more than 5,000 banks had gone out of business.
C the glorious and French Revolution
The totalitarian states usually don't allow any opposition parties to exist. If some people try to form a party, they usually end up in prison, are banished from the nation, or even murdered.
The reason why the totalitarian rulers prefer a one party system is in order to have all the power in the country, without having opposition that will constantly go public about the terrors and injustices that are happening. If there are more parties, than the people will start to support them, especially cause rarely who likes to live under a totalitarian ruler, thus the totalitarian ruler will face a situation where he/she will lose its power.
