"“Evolution is the long blur, a constant and living flow of branching relationships. One thing is always connected to another and another. Having no regard for our love of labels and organization, life rolls on as a continual stream of organic matter. The important thing about the origin of the human brain is not pinpointing some specific time, event, or fossil to declare a beginning in order to satisfy our desire for order. What matters is that we understand the process from which it emerged and how deeply rooted the modern human brain is to its past.”"
