The Changing Face of Evolutionary Theory?
Is evolution driven mainly by random genetic variation, or are there other factors at play? Michael Burdett reviews the scientific debate.
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".
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.
Theory, Prediction and Converging Lines of Evidence, Part 2
We have already discussed hind limb and hair loss in whales, and now we turn to one of the remaining questions: tooth loss in the lineage leading to modern toothless whales.
What is the genetic evidence for evolution?
Darwin developed his theory of evolution by looking at scientific evidence available in the mid-1800s. Since then, the whole field of genetics has developed, adding a powerful independent line of evidence in support of evolution. Genes show how the physical traits of living things are handed down and modified from one generation to the next. By comparing the DNA of many organisms, scientists can map the relationships between species. This map is in remarkable agreement with Darwin’s predictions. The structure of chromosomes and particular genetic sequences point to the conclusion not just of common design, but common descent as well.
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.
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.
The Origin of Biological Information, Part 4
Are all proteins so connected? If evolution has produced the diversity in protein form and function that we observe today, this pattern should be common.
Genesis and the Genome
This article provides an overview of genomics evidence for common ancestry and hominid population sizes, and briefly discusses the implications of these lines of evidence for scientific concordist approaches to the Genesis narratives.
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: 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...
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.
