Series: Evidences for Evolution (7 entries)

This technical series, co-written by Darrel Falk and David Kerk, looks into the evidence for evolution in order to dispel doubts that people may have about this well-supported theory. They look at three things specifically: the separate methods which reveal of the age of the earth, the unfolding history of whale evolution, and finally the common trends of heart development in vertebrates.

 

Series: Saturday Science Links (22 entries)

The biggest science stories of the week are reviewed.

 

Paleogenomics: A new generation of fossil hunters dig up God’s story of creation

Researchers in the emerging field of Paleogenomics are investigating the past using genetic research.

 

Series: Reviewing “Darwin’s Doubt” (11 entries)

 

Series: Adam, Eve, and Human Population Genetics (12 entries)

 

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: Made in the Image of God: The Theological Implications of Human Genomics (4 entries)

This series by Denis Alexander reflects on advancements in genomics as well as their theological implications. He focuses on the relatedness of hominin genomes, arguing that this does not interfere with the image of God in humans. The image of God depends more on the capacity for relationship and covenant, not on a list of particular physical qualities. He then discusses why the recent studies of genomics provide “no grounds for genetic determinism.”

 

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".

 

Biblical and Scientific Shortcomings of Flood Geology, Part 3

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.

 

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.

 

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.

 

Possibilities and Second Chances

In today’s video, Dr. Rick Colling states that evolution is not merely the imposition of death and destruction and survival of the fittest. Rather, it is about second chances.

 

Series: Understanding Evolution: Is There “Junk” in Your Genome? (5 entries)

One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this installment on “junk DNA”, we explore how genomics can be employed to test for non-functional sequences by comparing sequences between related organisms.

 

Where is the Genetic Evidence for Evolution?

The discovery of DNA has revolutionized our understanding of common descent, particularly in the past few decades. Mutated genes spread through populations over generations, leading to evolutionary change. In this podcast, we look at several examples of genetic evidence for evolution.

 

New Limbs from Old Fins, Part 2: Comparative Anatomy

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.

 

Series: The Cambrian "Explosion", Transitional Forms, and the Tree of Life (8 entries)

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.

 

Series: Signature in the Pseudogenes (3 entries)

This brief series explains the significance of pseudogenes. Darrel Falk and Dennis Venema demonstrate how the theory of common descent provides a fine framework in which to interpret the existence of these once-functional genes. They also discuss the relationship of various primates and other mammals based on shared pseudogenes. The evidence in support of evolutionary theory, they argue, is compelling when examining the rich history disclosed in the DNA of every organism.

 

Signature in the Synteny

In some ways, comparing the DNA sequence between related organisms is like reading alternative history novels. The hypothesis of common ancestry between similar organisms makes a very straightforward prediction about their genomes...

 

In The Bones

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.

 

Evidence for Evolution in the Mouths of Birds

A friend tells me the most important task for The BioLogos Forum is to present evidence of evolution in ways people without a biology background can understand.
