The book aroused international interest and a widespread debate, with no sharp line between scientific issues and ideological, social and religious implications. Much of the initial reaction was hostile, but Darwin had to be taken seriously as a prominent and respected name in science. There was much less controversy than had greeted the 1844 publication Vestiges of Creation, which had been rejected by scientists, but had influenced a wide public readership into believing that nature and human society were governed by natural laws. The Origin of Species as a book of wide general interest became associated with ideas of social reform. Its proponents made full use of a surge in the publication of review journals, and it was given more popular attention than almost any other scientific work, though it failed to match the continuing sales of Vestiges. Darwin's book legitimised scientific discussion of evolutionary mechanisms, and the newly coined term Darwinism was used to cover the whole range of evolutionism, not just his own ideas. By the mid-1870s, evolutionism was triumphant.
Why was the book taken seriously even though much of the response was hostile?
Darwin had to be taken seriously as a prominent and respected name in science

Zakaria Mohieddin, who was Nasser's vice president, said that Nasser gradually changed during his reign. He ceased consulting his colleagues and made more and more of the decisions himself. Although Nasser repeatedly said that a war with Israel will start at a time of his, or Arab, choosing, on 1967 he started a bluffing game "but a successful bluff means your opponent must not know which cards you are holding. In this case Nasser's opponent could see his hand in the mirror and knew he was only holding a pair of deuces" and Nasser knew that his army is not prepared yet. "All of this was out of character...His tendencies in this regard may have been accentuated by diabetes... That was the only rational explanation for his actions in 1967".
What did Nasser do over the years of his rule?
gradually changed

Usually, a federation is formed at two levels: the central government and the regions (states, provinces, territories), and little to nothing is said about second or third level administrative political entities. Brazil is an exception, because the 1988 Constitution included the municipalities as autonomous political entities making the federation tripartite, encompassing the Union, the States, and the municipalities. Each state is divided into municipalities (municipios) with their own legislative council (camara de vereadores) and a mayor (prefeito), which are partly autonomous from both Federal and State Government. Each municipality has a "little constitution", called "organic law" (lei organica). Mexico is an intermediate case, in that municipalities are granted full-autonomy by the federal constitution and their existence as autonomous entities (municipio libre, "free municipality") is established by the federal government and cannot be revoked by the states' constitutions. Moreover, the federal constitution determines which powers and competencies belong exclusively to the municipalities and not to the constituent states. However, municipalities do not have an elected legislative assembly.
What two levels equal a federation?
the central government and the regions
