The new Gallup survey shows in broad strokes the challenge we face. But more nuanced surveys find that only 8% of Americans are convinced creationists whose beliefs are dear to them, and only 4% are convinced atheistic evolutionists whose beliefs are dear to them. The vast majority of Americans are not sure of their position and are open to a conversation.
Christian theology asserts that humans are spiritual creatures, a unity of body and spirit or “soul,” integrated, not reducible downwards to mere matter or upwards to mere spirit.
The BioLogos Forum is pleased to present this infographic about the current anthropological understanding of human evolution, which takes into account research into both physiological and cultural developments among our ancient ancestors.
This BioLogos videocast addresses the age of recently discovered hominid fossils and how scientists are able to obtain those dates.
In recent decades, scientists have discovered more about the beginnings of humanity. The fossil record shows a gradual transition over 5 million years ago from chimpanzee-size creatures to hominids with larger brains who walked on two legs. Later hominids used fire and stone tools and had brains as large as modern humans. Fossils of homo sapiens in east Africa date back nearly 200,000 years. Humans developed hearths for fire, stone points for spears and arrows, and cave paintings by 30,000 years ago. By 10,000 years ago, humans had spread throughout the globe. Genetic studies support the same picture. Humans share more DNA with chimpanzees than with any other animal, suggesting that humans and chimps share a relatively recent common ancestor. Also, the same defective genes appear in both humans and chimps, at the same locations in the genome—an observation difficult to explain except by common ancestry. Genetics also tells us that the human population today descended from more than two people. Evolution happens not to individuals but to populations, and the amount of genetic diversity in the gene pool today suggests that the human population was never smaller than several thousand individuals. Yet all humans, of all races, are descended from this group. Humanity is one family.
Original sin often refers simply to the current state of humanity, in that all have sinned and fallen short of the glory of God (Romans 3:23). Evolution does not raise questions about our current state of sinfulness. It does, however, raise questions about how and when the first sin occurred, and how this fallen state was transmitted to all people. The sciences of evolution and archaeology can provide some insight into these questions but are not equipped to answer them. These questions are theological, and over the centuries the church has considered many possible answers. Some of these options are consistent with the scientific evidence currently available.
Scholar and musician Jeff Warren addresses the questions of how music is meaningful, and where that meaning resides, by looking at the popular ideas that musical meaning is entirely subjective to the listener and that the meaning of music can be universal. He also explores the recent trend of attempting to explain music via neuroscience. Finally, he looks into the reasons why music continues to play such a critical role in the worshiping life of the Church.
In this video, Pääbo covers a lot of ground, noting several lines of genetic evidence for the evolution of modern humans from earlier hominids in Africa, as well as for the interbreeding between early humans and Neanderthals.
This blog series by Dennis Venema undertakes the task of clarifying numerous aspects of evolution that often become misconstrued by Christians. He first discusses the idea of speciation in a population over time, later applying it to the speciation process that occurred among hominids (human ancestors) which led to modern humans. He continues to support this idea by exploring so called “Mitochondrial Eve,”“Y Chromosome Adam” and other compositional clues of the human genome.
If the tape was rewound and evolution started over from scratch, Conway Morris says, the evolutionary details would be different, but the end result would be similar: a species characterized by intelligence and complex civilization.
All science can say is that there was never a time when only two people existed on the earth: it is silent on whether or not God began a special relationship with a historical couple at some point in the past. This subtle but extremely important point was missed entirely in the NPR story.
Denis Alexander begins this five part series by discussing both what a model is and whether it is appropriate to use one when building a bridge between scientific truths and theological truths. Providing evolutionary facts about the origins of humans as well as discussing the origin and meaning of Adam in Genesis, he constructs what he calls a Retelling model and a Homo divinus model. Both approaches, he concludes, “suggest that human evolution per se is irrelevant to the theological understanding of humankind made in the image of God.”
As an evolutionary biologist I am fascinated by the emergence of cognitive abilities that make us so distinctive from other living species. There are, however, risks in making up evolutionary "just-so" stories to explain the origins of complex human beliefs.
The tenth anniversary of the human genome has been marked by some striking new genetic insights into human evolution and diversity. Do these new discoveries have any significance for the dialogue between science and religion?
Is the human race descended from one ancestral pair in the recent past? Are we, as C.S. Lewis puts it in his Chronicles of Narnia, the “sons of Adam and daughters of Eve”?
The Denisovans, an extinct hominid group that interbred with modern humans, made the news again lately with the publication of a more detailed study of their genome. One of the many interesting findings was that the Denisovans share the same chromosome 2 fusion that modern humans have.
What does it mean to be human? For the Christian, the answer is complex. In part, it is a reflection of being created in the image of God. But does the science of human evolution pose a threat to that uniqueness?
They all together cry out in unison with a loud voice—“Created!” However, they also, in a subtle, but persuasive whisper, add the all-important qualifying phrase—“…slowly and not in an instant!”
