26、he time just by looking at this “flower clock“. No one really understands why flowers open and close like this at particular times, but recently some interesting experiments have been done. Once, flowers were put in a laboratory in constant darkness. One might predict that these flowers, not having
27、any information about the time of day, would not open as they usually do. But in fact they continue to open as if they were in a normal garden.

29、y, the flowers in the laboratory open because their “internal clock“ tells them to do so.

Brown and his colleagues could not understand this until they asked
31、 themselves the question: “If Illinois were on the sea, when would high and low tides take place?“ He found that the oysters were opening and closing at exactly these times. Brown concluded that the oysters cycle was controlled by changes in the atmosphere changes that, in places where there is a se
