Answer:

The term "survival of the fittest" was first used by the Victorian naturalist Herbert Spencer as a metaphor to help explain natural selection, the central element of Charles Darwin's revolutionary theory of evolutionary change, first published in 1859 in his famous book, The Origin of Species by Means of Natural Selection.

In this extremely influential and important book, Darwin reasoned that all species are capable of producing an enormously larger number of offspring than actually survive. He believed that the survival of progeny was not a random process. (In fact, he described it as a "struggle for existence.") Rather, Darwin suggested that those progeny which were better adapted to coping with the opportunities and risks presented by environmental circumstances would have a better chance of surviving, and of passing on their favorable traits to subsequent generations. These better-adapted individuals, which contribute disproportionately to the genetic complement of subsequent generations of their population, are said to have greater reproductive "fitness." Hence the use, and popularization, of the phrase: "survival of the fittest." (Darwin also used another, more awkward expression to explain the same thing: the "preservation of favored races in the struggle for life." In fact, this is the subtitle that he used for The Origin of Species by Means of Natural Selection.)

Darwin's theory of evolution by natural selection is one of the most important concepts and organizing principles of modern biology. The differential survival of individuals that are more-fit, for reasons that are genetically heritable, is believed to be one of the most important mechanisms of evolution. And because of its clarity, the phrase "survival of the fittest" is still widely used to explain natural selection to people interested in understanding the evolution of life on Earth.

What did william penn consider his colony to be "fundamental order" a "holy experiment" a "royal church" a "personal estate"?

Georgia [21]

The answer would be "Holy Experiment." This was the word William Penn used for the ultimate government he established for Pennsylvania in 1681, when he got the contract for that colony from King Charles II of England. Penn supposed that the contract was a present from God, "that an instance may be set up to the states: there may be area there, though not here, for such a holy experiment."

An ancient philosopher once said: "Man is the measure of all things." The statement points to the idea that man is at the center

MAVERICK [17]

This phrase is attributed to Protagoras, a pre-Socratic Greek philosopher. Although the phase is open to interpretation, one of its possible meanings is the fact that humans are at the center of all existence. Moreover, human perception is the standard of objectivity by which everything else is measured. Therefore, this phrase implies that there is no "force" or "being" outside of humans that can provide us with answers to the questions of existence.

This view is closer to that of Greek religion than to that of Hebrew religion, Judaism. Judaism believes in an <em>objetive</em> truth and <em>objective</em> moral rules, contained in the Torah. Moreover, Jews believe that there is one single God, which is omnipotent and all-knowing, and therefore truth emanates from him and not from men.

On the other hand, Greek religion contains many different gods, all of which are imperfect. This suggests that the behaviour or "teachings" of the gods cannot provide us with an objective truth. Humans need to create their own moral codes and their own assumptions about the world in order to establish their societies. Moreover, gods participate very little in human life and when they do they often create chaos or are defeated, suggesting that gods are fallible and cannot control the whole world. These assumptions mean that Greeks believe humans are significantly autonomous and independent from gods, allowing them to believe that they are at the center of all knowledge and experience.
