Time zones are a universal standard used to mark the hours of the day in different locations. The reason time zones are necessary is to correct for the fact that, geologically speaking, people in different locations experience the hour at different “times” of the day. The Royal Observatory in Greenwich If there were no time zones, "noon," for instance—when the sun is at its highest point in the sky—would occur at 5:05 in one place and 12:36 in another, defeating the purpose of having standard time across regions.

A lot of human beings are monogamous, but did you know that hardly any other animals practice any form of monogamy? In nature, monogamous pairing refers to mating systems where a pair of animals stick together to raise their offspring. That “family” structure is actually the main feature of the monogamy. This isn’t quite the same thing as sexual monogamy, though the two usually go hand in hand. According to the National Science Foundation, scientists currently estimate that only about 3-5% of the mammal species on Earth practice monogamy, whether for the short term or the long term.
