11、 Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.The newly discovered lake is believed to date f

They describe in the Royal Society journal，Proceedings B，how this could a
17、ssist in the future study of empathy(同感，共鸣)The work could also help explain if and how computer games might cause children to imitate what they see on screen.Previous studies have already shown contagious yawning in chimpanzeesstimulated by videorecorded footage of yawns.“We wanted to expand on that
18、，” explained Matthew Campbell，a researcher from Emory Universitys Yerkes National Primate Research Center and lead author of the study.“Were interested in using cartoons for presenting stimuli to animals, because we can control all the features of what we show them，” he continued.Although Dr Campbel
