Proconsul Facts and Figures

Name: Proconsul (Greek for before Consul, a well-known circus ape); pronounced pro-CON-sul Habitat: Jungles of Africa Historical Epoch: Early Miocene (23-17 million years ago) Size and Weight: About 3-5 feet long and 25-100 pounds Diet: Omnivorous Distinguishing Characteristics: Monkey-like posture; flexible hands and feet; lack of tail About Proconsul As far as paleontologists can tell, Proconsul marks the time in primate evolution when the old world monkeys and apes diverged from a common ancestor — which means, in laymans terms, that Proconsul may (or may not) have been the first true ape. In fact, this ancient primate combined various characteristics of monkeys and apes; its hands and feet were more flexible than those of contemporary monkeys, but it still walked in a monkey-like way, on all fours and parallel to the ground. Perhaps most tellingly, the various species of Proconsul (which ranged from a smallish 30 pounds or so to a largish 100) lacked tails, a distinctly ape-like trait. If Proconsul was, in fact, an ape, that would make it distantly ancestral to humans, and perhaps even a true hominid, though its brain size indicates that it wasnt much smarter than the average monkey. However it winds up being classified, Proconsul holds a special place in hominid paleontology. When its remains were first discovered, back in 1909, Proconsul was not only the oldest ape yet identified, but the first prehistoric mammal ever to be unearthed in sub-Saharan Africa. The name Proconsul is a story in itself: this early Miocene primate wasnt named after the revered proconsuls (provincial governors) of ancient Rome, but after a pair of popular circus chimpanzees, both named Consul, one of which performed in England and the other in France. Before Consul, as the Greek name translates, may not seem very dignified for such a remote human ancestor, but thats the moniker that has stuck! Many people mistakenly believe that Proconsul was one of the immediate predecessors of Homo sapiens. In fact, though, this ancient primate lived during the Miocene epoch, from about 23 to 17 million years ago, at least 15 million years before the first recognizable human ancestors (like Australopithecus and Paranthropus) evolved in Africa. Its not even a sure thing that Proconsul spawned the line of hominids that led to modern humans; this primate may have belonged to a sister taxon, which would make it more of a great-great-great uncle a thousand times removed.

The Success of the Bolsheviks in Gaining Power in Russia...

The Success of the Bolsheviks in Gaining Power in Russia by 1922 In February 1917, the Bolshevik party was small and irrelevant. The leadership was abroad and there was little consistency of purpose among the party in Russia. However, by the summer of 1922, the Bolsheviks had become the dominant force, and a new communist state had emerged from their success. The purpose of this essay is to explain this transformation. The abdication of Tsar Nicholas II and the collapse of the Romanov dynasty threw Russia into a state of turmoil. The elites had withdrawn their support for the Tsar after a series of disastrous defeats in the war and continued social and economic problems. In the wake of the†¦show more content†¦Despite the financial considerations, the Provisional Government felt obliged to continue the war out of a sense of loyalty to Britain and France. In addition, they were reluctant to leave the war without salvaging some prestige and pride from the current situation. They were still hopeful of an allied victory. However, the decision to continue with the war was to prove extremely unfortunate. It was unpopular, as there appeared to be few aims to the continued fighting. The government quickly lost the support of a large proportion of the troops. These disillusioned peasants in uniform provided excellent targets for Bolshevik propaganda. What is more, the Russian situation in the wa r worsened and humiliating defeat began to loom large on the horizon. Russia was a poverty stricken, backward power in 1917. It also had a majority peasant population. The continuation of the war meant that the key issues of peace, bread and land that Lenin so aptly highlighted could not be addressed. Reforms and visible improvement in the peasant way of life were vital if the government wished to gain their support and maintain its power. However, revolutionary forces, suppressed under Tsarist Russia came to the surface under the new, weaker and less repressive Provisional Government to create a body known as the Soviet. This body created aShow MoreRelatedThe Russian Revolution s Influence On Joseph Stalin1436 Words   |  6 Pageson Joseph Stalin Joseph Stalin greatly influenced Russia and the international community in the years 1924 through 1932.
