The same thing happens throughout evolutionary development.

同样的事情发生在整个进化发展过程中。

When I say that chemicals alone will not give you consciousness, I am speaking of the theory held that physical matter, chemicals and atoms, that were inert and lifeless, suddenly through some metamorphosis attained the conscious state through an evolutionary development.

当我说单单是化学物不会给你们意识，我说的是这样一个理论：那些原本是惰性的、无生命的自然物质，化学物和原子，突然通过某种蜕变，经过了演化的发展，而达到了有意识的状态。
