在过去10年中,天文学家已经发现了400多颗新行星。找到地外生命存在的证据或许指日可待。但问题是:当我们看见外星生命时,我们真的能够认出它们吗?为此,我们需要考虑外星进化历史会怎样塑造外星生命形式以适应它们自己所处的环境。
In the past 10 years, astronomers have discovered more than 400 new planets. Finding evidence of the existence of extraterrestrial life may be just around the corner. But the question is: can we really recognize them when we see extraterrestrial life? For this reason, we need to consider how the alien evolutionary history shapes alien life forms to suit their own circumstances.
