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.
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.
James Kidder explains how a stunning fossil discovery affects our understanding of human evolution.
This week's news features volcanoes, skeletons, and stars, as well as a thought-provoking new book from InterVarsity press.
From science and religion blogs: quantum uncertainty and God, the remarkable fact that we have come to understand our place in the created order, and the role of theology in making wise choices about the use of technology.
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.
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 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.
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.
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?
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.
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.
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.
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.
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.
