Series: Adam, Eve, and Human Population Genetics (15 entries)

 

Series: The Human Fossil Record (20 entries)

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.

 

What is the genetic evidence for human evolution?

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.

 

Series: Understanding Evolution (4 entries)

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.

 

Denisovans, Humans and the Chromosome 2 Fusion

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 is Evolution?

The word evolution can be used in many ways, but in biology, it means descent with modification. In other words, small modifications occur at the genetic level (i.e. in DNA) when a new generation descends from its parents. Over many generations these modifications can result in significant differences from the ancestral population.

 

What is the genetic evidence for human evolution?

The more research that is done on DNA, the more evidence we find that all life is related.

 

Series: Saturday Science Links (27 entries)

The biggest science stories of the week are reviewed.

 

Series: Evolution Basics (50 entries)

Written by BioLogos Fellow of Biology Dennis Venema, this series of posts is intended as a basic introduction to the science of evolution for non-specialists.

 

Neanderthals, humans and interbreeding: old bones, new evidence

For Evangelicals interested in the evolutionary history of our species, the results of a new study are a “smoking gun” for human/Neanderthal interbreeding.

 

What Americans Think and Feel about Evolution

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.

 

Humanity as and in Creation

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.

 

Evolution and Christian Faith Grantees Announced

Congratulations to the 37 winners of the Evolution & Christian Faith (ECF) grants competition! ECF is a new BioLogos program designed to support projects and network-building among scholars, church leaders, and parachurch organizations.

 

Where are the Transitional Fossils?

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.

 

Series: Decoding ENCODE (8 entries)

The BioLogos Foundation explains to the findings of the Encyclopedia of DNA Elements (ENCODE) project and responds to the claims that its discoveries challenge the theory of evolution, especially regarding so-called "junk DNA".

 

David Lack and Darwin’s Finches

Considering the immense popularity of "Darwin's finches", it is quite surprising to learn that Charles Darwin himself had very little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.

 

Being Human (Infographic)

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.

 

Hominids Lived Millions of Years Ago, but How Can We Tell? (Videocast)

This BioLogos videocast addresses the age of recently discovered hominid fossils and how scientists are able to obtain those dates.

 

How does original sin fit with evolutionary history?

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.

 

Is There “Junk” in Your Genome? Part 4

Now that we have covered significant ground with respect to what various classes of pseudogenes are and how they arise, we are now able to properly evaluate antievolutionary arguments put forward in an attempt to discredit these lines of evidence for evolution.
