QUES: Among predators there is a large degree of specialization. Many predators specialize in hunting only one species of prey. Others are more opportunistic and will kill and eat almost anything (examples: humans, leopards, dogs and alligators). The specialists are usually particularly well suited to capturing their preferred prey. The prey in turn, are often equally suited to escape that predator. This is called an evolutionary arms race and tends to keep the populations of both species in equilibrium. Some predators specialize in certain classes of prey, not just single species. Some will switch to other prey (with varying degrees of success) when the preferred target is extremely scarce, and they may also resort to scavenging or a herbivorous diet if possible.[citation needed]
What is the purpose of an evolutionary arms race?

ANS: keep the populations of both species in equilibrium

QUES: The roots of Orthodox Judaism can be traced to the late 18th or early 19th century, when elements within German Jewry sought to reform Jewish belief and practice in the early 19th century in response to the Age of Enlightenment, Jewish Emancipation, and Haskalah. They sought to modernize education in light of contemporary scholarship. They rejected claims of the absolute divine authorship of the Torah, declaring only biblical laws concerning ethics to be binding, and stated that the rest of halakha (Jewish law) need not be viewed as normative for Jews in wider society.
