Instead of looking for changes in genes that take many generations to accumulate until they can be detected, we have measured natural selection directly. This method can reveal selection in action, working over periods of time as short as one generation – so that it can answer the question of whether modern culture has stopped evolution.
而包括我在内的一些科学家则选择了另一种方式。我们不是去寻找那些经过许多代人逐渐积累并最终显现的基因特征，而是直接对自然选择进行测量。这种方法可以揭示出那些正在发生的进化选择，而这种选择的发生时间可以缩短至一代人以内——因此也可以用来回答现代文明是否令进化停滞的问题。
