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.

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.

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.

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".

Many Christians believe that they face a painful choice-- either life was designed by God or it is an evolutionary product of natural selection. Charles Darwin himself believed in this dichotomy, and people ever since have felt the need to "choose sides". However, looking back at history, we find that one of Darwin's chief scientific colleagues, Asa Gray, did not share this perspective. In this three-part essay, part 1 charts the relationship of Asa Gray and Charles Darwin. Part 2 describes Darwin's struggle with the problem of natural evil and design in nature, and part 3 explores how Asa Gray was able to embrace evolution without rejecting the idea of design.

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

Last week, Tennessee legislators approved a bill on science education (the Teacher Protection Academic Freedom Act) that has stoked controversy around the country.

Steve Benner, a Distinguished Fellow of The Foundation for Applied Molecular Evolution in Gainesville, Fla., looks at what the role of a scientist should be. Benner looks specifically at "falsifiability", the acceptance of uncertainty, and the place of the scientist in public discourse.

In this series, Dennis Venema describes his personal journey that took him away from the Intelligent Design arguments toward the evolutionary creation worldview. Through careful and honest research, he discovered ID scientific reasoning to be analogy-based, in sharp contrast to evolutionary science, which was supported by concrete data. After accepting this view, God’s presence ever strengthened him as he explored the compatibility between the Bible and God’s creative mechanism.

Media-hungry atheist, creationist and religious fundamentalist provocateurs have dominated the science and religion narrative for the past decade. A recently published large-scale survey of college students, however, finds that the call to arms has fallen on deaf ears.

In this short video, physicist Ard Louis expresses some doubts about Intelligent Design, noting that his primary resistance to the movement is based on theological grounds rather than science.

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.

Towards the end of the last school year, the Tennessee legislature passed the Teacher Protection Academic Freedom Act, a law that became more popularly known as the “Monkey Bill.” I was doing research in a Tennessee high school biology classroom the morning that I learned that the bill had passed.

In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris over the idea of evolutionary convergence.

The topic of Intelligent Design (ID) comes up frequently here. Because ID can be hard to pin down, it’s worth pausing to remind ourselves what we’re talking about when we use the term on this site.

In this video clip, Oxford University biophysicist, Ard Louis posits that one of the reasons Christians are hostile to evolution is that they latch onto a particular definition, which puts it in conflict with their theological convictions.

A complex biological structure with many interacting parts might appear, at first glance, as if it were originally created in its present form with all its interlocking components fully formed and intact. It doesn’t seem possible that they developed step by step via biological evolution. In Darwin’s Black Box, Michael Behe introduces a term that he and other proponents of Intelligent Design use for this concept: irreducible complexity.

If God himself is willing to die, particularly in such a gruesome way, then perhaps we should at least consider the possibility of God allowing the death of other creatures, too. But would this really be compatible with what we know of God through Scripture?

There are two opposite errors which need to be countered about the fossil record: 1) that it is so incomplete as to be of no value in interpreting patterns and trends in the history of life, and 2) that it is so good that we should expect a relatively complete record of the details of evolutionary transitions within all or most lineages.

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.
