Physicists were thinking far ahead of their time in a very intelligent way．They saw what was going to happen before it actually did．They thought about modern computing in the 1950s，they imagined a lot of the technological progress that we would see only decades later in the real world．They were asking very theoretical questions because these ideas were still so far removed from practice．And they asked very moral questions as well，because the things they conceptualized could be used for great good or for great evil．It could go either way，so moral judgments had to be made．

Why do animals of different species communicate with one another?

The whales stranded on the beach followed the dolphin to safety probably because

Dolphins communicate with one another, using all the following types of signaling EXCEPT

Before Moko the dolphin turned up，the beached whales were in clear distress．But when Moko arrived at Mahia beach on the east coast of New Zealand?S North Island，their mood changed and they followed him to safety． The ability of some animals to communicate is well known. What?s less well documented，however，is the communication between species．Justin Gregg, vice president of the Dolphin Communication Project，said it is possible that a dolphin and a whale could communicate in some way．“But it wouldn?t be instructions like ?Hey，buddy，the open ocean is over here.Follow me, ?"he says． Dolphins use three forms of signaling to other dolphins—whistles，clicking and postures．A whale might have signals in common with a dolphin，just as different species of dolphins are known to share signals which might theoretically allow a form of basic inter species communication．But just as it?s possible that Moko the dolphin and the stranded whales shared a signal，it is also possible that the whales just saw a vaguely similar creature and followed it． There are many reasons why different species communicate，says Vincent Janik，lecturer at the Sea Mammal Research Unit at St Andrew?s University．“The animals exploit the systems of others for their own benefits．Sometimes the benefits are the same for each，therefore they share information．Sometimes they are trying to take advantage of the other．Getting food may not be to the advantage of the one giving up the food” What happened after Moko the dolphin appeared at Mahia beach?
