The efficient-market hypothesis emphasizes that arbitrage will rapidly eliminate any profit opportunities and drive market prices back to fair value. Behavioral-finance specialists may concede that there are no easy profits‚ but argue that arbitrage is costly and sometimes slow-working‚ so that deviations from fair value may persist.

They believed that Earth had a chemically reducing atmosphere. This produced monomers. These monomers formed a "soup‚" that developed organic

Compare the Social Brain Hypothesis and the Visual Specialisation Hypothesis The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group
