可居住行星的寿命和智慧生命的发展
The longevity of habitable planets and the development of intelligent life
摘要：
为什么我们物种的出现需要一个类似于我们星球整个可居住时期的时间尺度？卡特（Carter，2008）曾将我们的晚出现解释为观察者通常需要很长的发展时间，这意味着智慧生命是罕见的。在这里，我们提出了另一种解释，它简单地断言，许多行星具有短暂的可居住期。我们还提出，形成观察员的限速步骤是从最初的微生物状态的物种的扩大。在这种情况下，智能生命的发展是一个缓慢但几乎不可避免的过程，这大大增强了未来SETI实验的前景，如突破倾听项目。
英文摘要：
Why did the emergence of our species require a timescale similar to the entire habitable period of our planet? Our late appearance has previously been interpreted by Carter (2008) as evidence that observers typically require a very long development time, implying that intelligent life is a rare occurrence. Here we present an alternative explanation, which simply asserts that many planets possess brief periods of habitability. We also propose that the rate-limiting step for the formation of observers is the enlargement of species from an initially microbial state. In this scenario the development of intelligent life is a slow but almost inevitable process, greatly enhancing the prospects of future SETI experiments such as the Breakthrough Listen project.
