This week's news features volcanoes, skeletons, and stars, as well as a thought-provoking new book from InterVarsity press.
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 series, James Kidder provides an intriguing study on transitional fossils and the evolutionary history of modern humans. He begins by discussing the fossil record, explaining how new forms are classified. He then explains the physically distinguishing trait of humankind—bipedalism. From the discovery of Ardipithecus, the earliest known hominin, to the australopithecines, the most prolific hominin, Kidder focuses on the discovery, the anatomy, and the interpretation of these ancestral remains.
During his seminary education, Dr. Murphy also gained a deeper understanding of Luther’s theology of the cross, and he realized that it’s really the best way to approach the science and theology dialogue.
In this excerpt from the book Delight in Creation: Scientists Share Their Work with the Church, astronomer Deborah Haarsma shares her excitement about recent findings about our universe from a Christian perspective.
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.
At a press conference on July 4, 2012, and with 99.99994% confidence (5 sigma), CERN announced the discovery of a particle consistent with that of a Higgs boson (a.k.a. “the God particle”). This is very exciting for elementary particle physicists. But what is the Higgs particle, and what is its meaning?
The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity? Is there actually any theological or religious significance in Higgs physics at all?
BioLogos is pleased to share excerpts from Karl Giberson’s book The Wonder of the Universe: Hints of God in a Fine-Tuned World. It presents a two-part argument: in the first section Giberson outlines the history of our understanding of the universe, emphasizing the reliability of our knowledge of its properties and its history. In particular he outlines the remarkable evidence of design. In part two of the book, however, he discusses the complexities of drawing inferences from the design of the universe, cautioning against arguments that fine-tuning of the universe proves the existence of God.
Baylor University Physicist Gerald Cleaver describes the changing state of our understanding of the cosmos and suggests ways that Christians can make theological sense of a theoretical Multiverse.
The six-part series by Dr. Keller considers three main clusters of questions lay people raise with their pastors when introduced to the teaching that biological evolution and biblical orthodoxy can be compatible. As a pastor and evangelist, Keller takes these concerns seriously and offers suggestions for addressing them without requiring believers to adopt a particular view or accept a definitive answer.
In this brief series (taken from a 2009 paper), Jennifer Wiseman uses an excerpt from the famous hymn “How Great Thou Art,” to explain why the study of God’s creation can lead Christ’s followers into meaningful worship and overcome the obstacles which impede true praise. Creation as encountered through our senses is pondered by our minds, which flows into wonder-filled songs from the soul. She further explains how knowledge of creation will help Christians to address the moral dilemmas of science, and she encourages all to see the process of scientific inquiry as a means to discover God’s truth.
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.
I find that when many Christians think about the way God created our universe, they often bring a static expectation similar to what we bring to an ordinary statue. It’s as if we assume the physical realm were merely a rigid three-dimensional sculpture, immovable with time.
Providing the crutch for non-believers to lean on is a well-intentioned strategic error that has no benefit and likely does much harm. However, I am even more concerned about something else related to our construction of these crutches.
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.
