Thank you for asking, Jay. The book is called On the (Divine) Origin of Our Species. It will be out later this year; most likely not until Fall. As we get closer to its release, BioLogos has indicated that a set of articles drawn from the book will be posted and I look forward to preparing those. In the book, I explore what I consider to be the ramifications of the statement, “God is love” (I John 4:16) as it relates to the process of human evolution. If this has always been true (and, course, there is nothing more central to Christian theology than God’s love), there could have been no beginning to that love as our species was developing. God is love—period(!)—and it was through experiencing and responding to that love that our species came into being.
Here’s what I mean. Although the love of God was a constant during human evolution, there was something that changed. What did gradually change was the ability of an individual to recognize that another individual had a mind just like their own. In short, they developed a full Theory of Mind (ToM): the emergence of the capacity to understand that the other has thoughts too and that those thoughts resemble what takes place in one’s own mind. That almost certainly had never happened before in 600 million years of animal existence. As a result, not only were there individuals on earth who had the capability to “understand,” but with this change, there were beings who, in Aristotle’s terminology, “understand that they understand and perceive that they perceive.” Aristotle considered this to be the essence of human existence. Aquinas put this into the context of what it means to exist as the image of God on earth. He wrote, “As far as a likeness of the divine nature is concerned, [humans] seem somehow to attain a representation. . . imitating God not only in this—that he is and lives—but especially in this, that he understands”. And, significantly, Teilhard de Chardin—using the word “reflective” to describe human uniqueness—wrote, “Because we are reflective, we are not only different but quite other. It is not merely a matter of change of degree, but of change of nature, resulting from a change of state.”
So here’s my point. As our ancestors’ Theory of Mind became more sophisticated not only were they aware of the minds and feelings of others, but the God who is love was now able to speak into their “thought-life” in increasingly meaningful ways. (A good analogy is the changes which occur in how parents are able to communicate their love and expectations to their child as she/he moves out of babyhood.) John Wesley’s reflections on the human condition is relevant here and my colleague Michael Lodahl summarizes this well: “[For Wesley] there is no human being who has ever existed who was not deeply loved and immediately graced by God . . . Thus, no human being lives without the Spirit’s wooing to live compassionately and justly with (all) others. . . ‘Everyone has some measure of that light, some faint glimmering ray, which sooner or later, more or less, enlightens every man that cometh into the world.’” Although Wesley knew nothing of how extremely ancient human existence was, this principle, it seems to me, should translate back through all of humanity even as it was emerging in Africa. Indeed, I think Paul illustrated this principle when he wrote approvingly of non-Jews (prior to Jesus) who followed the impulses “written on their hearts” (see Romans 2:14,15). So, when did this “writing on hearts” and this “wooing of God’s Spirit” begin? I maintain that one would expect it to emerge as those in the human lineage gained the capacity “to understand” (Aquinas), and to “perceive that they perceive” (Aristotle), and to “reflect” (Teilhard).
These changes in the mind were taking place while our ancestors were living in small groups in Africa. Reputation for trustworthiness in small groups matters! Cohesiveness of the group matters! Thus, if a small population lived harmoniously as a result of their positive response to the “wooing of God’s Spirit” and following after the “writing on the heart” that Paul spoke of, and if they did so for generations, that population would thrive, especially when compared to a neighboring population fraught by distrust and discord. If a population lived “rightly” it would blossom, and if it did so consistently over multiple generations, such a population would thrive reproductively as well and, accordingly, would increase in number.
Now we come to the key point: genetic changes which enhanced cooperativity (like those that facilitated better communication or those which fostered an “others-centered” demeanor), would provide a selective advantage to that population. As a result they would frequently increase in the population. This, of course, is evolution and it is occurring through natural selection. But there is one important caveat to this way of looking at natural selection. In this case, natural selection occurs because individuals in the successful population are responding to that which is supernatural. The God, who is love, is encouraging them to act rightly and they are responding to that “writing on their hearts” which is the beckoning call of God’s Spirit to live in a manner grounded in love. The God who is love, in “partnership” with a group of individuals who are living into that love, fosters the emergence of a whole set of genetic changes that lead to a new way of being.
Obviously, there are book-length nuances to this. The point is, however, that a positive response to the love and wooing of the Spirit of God is a “selective force” that leads to genetic changes such that members of our species become finely tuned to respond and communicate effectively with each other.
There are many biblical, theological, and genetic questions that arise in response to all of this, and I try to look at these pretty carefully in the book. I might add though that I do believe in a real Fall, original sin, and a historical “Adam and Eve,” although I leave open the possibility that “Adam and Eve” consisted of a small community as opposed to just two individuals.
I hope this explains what I’m trying to do in the book. I realize it’s pretty dense, but I’ve tried to squeeze what takes me 100,000 words to do in the book, into a 1,000 word summary.
