Abstract
The central (foveal) retina takes about 30 milliseconds longer to signal to the brain than the peripheral retina. In the natural world, a 30 millisecond delay could have real consequences. Why did evolution do it this way?

中央（中央凹）视网膜向大脑发出信号所需的时间比周边视网膜长约 30 毫秒。在自然界中，30 毫秒的延迟可能会产生真正的后果。进化为什么要这样做？
