As practitioners of the emerging science of geology dug up previously unknown creatures of enormous size, readers of their books and articles responded with a mix of fascination and anxiety.
A common argument leveled against the theory of evolution is that scientists have not been able to produce transitional fossils that show the change of one species into another. In this podcast, we address a common misconception about what transitional fossils actually are.
In this talk, originally delivered at the BioLogos President's Circle meeting in October 2012, Dr. John Walton discusses the origin stories of Genesis 1-3, and why their focus on function and archetypes mean there is no Biblical narrative of material origins.
We find no compelling evidence that the earth’s geological features can be explained by a global Flood. Here we consider three lines of evidence: global salt deposits, the order of deposition of sediment layers in the Grand Canyon, and the sequence of fossils in geological strata.
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.
If evolution is true, whales are related to the even-toed hoofed mammals, and there should be transitional fossil forms dating from about 45 to 50 million years ago.
Critics of evolution sometimes portray the theory as an untestable historical conjecture, depicting it as fundamentally different from experimental science in the lab. But the hunt for the earliest tetrapods was an effort to test a hypothesis that had generated a prediction.
In this six part series, Brian Godawa takes a closer look at cosmography and its relationship to the Bible. After defining cosmography as a theory that describes features of the heavens and the earth, he relates how his own views about the universe have shifted. He then continues to talk about the Mesopotamian cosmography that is so consistently reflected in Scripture. This view of the universe includes aspects such as the firmament, the pillars, the underworld, the heavens above, the watery abyss. He then explains how one understands these concepts in terms of modern scientific thought.
Many evolutionary critics have identified the Cambrian Explosion as a stumbling block to the theory of evolution, arguing that the “expected transitions between major invertebrate phyla are absent, and that the suddenness of their appearance in the fossil record demonstrates that evolutionary explanations are not viable.” Keith Miller argues that the Cambrian Explosion is not so problematic as these opponents claim after all.
To understand and apply Genesis 1 correctly, we have to consider issues of genre and intention. Too often these chapters are read as if they present a purely straightforward historical and even scientific account of cosmic and human origins.
In this video, John Walton talks about ancient myth and how we might better understand it if we think about its intended functionality—that is, myths were a way to explain a culture’s origin and universal significance though they lacked the advances of scientific discovery.
In this video Conversation, N.T. Wright emphasizes the importance of understanding the context of biblical texts in order to know whether to read them as literal or metaphorical narratives.
It has been my experience that many Christians have not given sufficient thought to how the Old Testament was composed––that is, to the "human" side of the inspiration of Scripture.
I am a fan of the blog "Jesus Creed." Recently it published an interesting post about the transition from fins to limbs as evidenced by fossils of an organism trapped in sediment 375 million years ago.
Fossils provide a unique view into the history of life by showing the forms and features of life in the past. Fossils tell us how species have changed across long periods of the Earth’s history. For instance, in 1998, scientists found a fossil showing an animal at the transition from sea creature to land creature. This tetrapod had a hand-like fin, confirming a prediction of evolutionary biology. Though the fossil record does not include every plant and animal that ever lived, it provides substantial evidence for the common descent of life via evolution. The fossil record is a remarkable gift for the study of nature.
Geologist Keith Miller examines the "Cambrian Explosion", a period of rapid evolutionary diversification approximately 575 million years ago, and whether it poses a challenge to evolutionary theory. From the June 2014 issue of Perspectives on Science and Christian Faith from the American Scientific Affiliation.
In today's video, Brian McLaren discusses the value of considering Scripture in light of the cultures that surrounded them. The Biblical writers were aware of the myths of the power nations that surrounded them, but flipped their stories on their heads to reveal truth about God.
In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris over the idea of evolutionary convergence.
