https://youtu.be/-jpoxCZgZKQ Is the human genome highly functional or mostly junk? This is a question that is not only being asked in the creation-evolution debate; it is a question raging in the ivory tower as well. The 'old guard' is much more likely to resist any claim that large swaths of the genome are useful. The 'young punks' in science is more willing to accept the obvious fact that the genome is highly functional. Who is going to win? In this episode, Dr Rob puts a few more nails in the coffin of junk DNA.. Notes and links:' Carter 2023 What proportion of the human genome is actually functional?

No, the size of the genome has not changed, but the number of genes we thought it contains certainly has. After lots of double checking, there are fewer known protein coding genes today (~19,000) than there were when the human genome was first published, and even that count (~23,000) was shockingly small, according to the predictions of the world's top geneticists. The nature of the genome has consistently surprised people, but mostly because they applied Darwinian concepts to it. Instead, the genome is a wonderful testimony to the engineering prowess of God, who built something unexpected.

Chromosomal recombination is an essential part of the life cycle of all sexually reproducing organisms. Yet, the system is complex, involving hundreds to thousands of proteins and RNAs. It also involves DNA repair pathways, which are themselves incredibly complex. The newest available information on recombination tells us it is mutagenic, meaning that recombination erodes the very places where recombination happens. How did such a system arise by chance? Can we assume the recombination rate has always been the same? What happens when a new allele arises in the protein that controls recombination? What is the mutation burden caused by this important system? Finally, how does this affect the creation-evolution debate? Links and notes: 15 Questions for evolutionists, #8 How did sex originate?

My new video made quite a splash! Apparently, lots of Christians are asking questions about the DNA we can now pull from very old skeletons. How do they do it? What are the data telling us? How is it even there, if the bones are as old as claimed? Without revealing too many details about what is in the main presentation, here I am just talking about ancient DNA and its implications for the creation-evolution debate. I also throw in a few things I was not able to address in the main presentation, including the genetics of ancient Canaanites and Philistines found in and around Israel.

African cichlids are a diverse group of fishes that have frequently been used as evidence for evolution. Yet, now that the genomes of several hundred species have been published, the true history of this group has been revealed. All parties must now acknowledge that the many species arose quickly, from a common stock. In many ways, African cichlids fit beautifully into the biblical model of 'created kinds'.

Darwin's finches have long been considered an icon of evolution. A recent analysis included 40 years of morphological measurements and genealogy tracing among four finch species on a small island in the Galapagos chain. This was coupled to 30 years of DNA sampling, including the recent sequencing of nearly 4,000 finch genomes from the same small island. The results tell us a LOT about biblical views of speciation, natural selection, and 'change over time'.

A new paper claims that the pre-human population went through an extremely small and extremely long population bottleneck. Starting about one million years ago, the population was reduced to at most 1,280 "breeding individuals" and this lasted for over 100,000 years. To get there, they examined thousands of human genomes and assumed that all mutations are neutral. What would happen if we applied real-world mutation affects to the data? You know it. We would have gone extinct. The mutation burden would have driven us to extinction. Instead, what they really discovered was the we came from a very small founding population with only a little diversity. This fits perfectly within the Adam and Eve model of human ancestry.

The opponents of biblical creation have made some glaring errors in their criticisms of prior work on human-chimpanzee genetic differences. Specifically, several of their claims are in conflict with both theory and experiment. I document these here in detail. They have also shown a rudimentary understanding of how scientific data needs to be 'weighted' and they completely misunderstand how BLAST is supposed to work. Despite the high level of vitriol I have received so far, I submit this detailed analysis of their work for your review.

This is the second installment in a now multi-part series on human and chimpanzee genetic differences. I had a lot of pushback from my last episode, including negative reviews posted by Gutsick Gibbon, Creation Myths, and Dapper Dinosaur. Unperturbed, I push on. Here, I lay out some of the arguments in more detail and discuss many of the problems people are having when using one particular program, BLAST, to assess similarity between the two species. I will address the results of Gutsick Gibbon specifically in Part 3, but this was filmed before I got most of my experimental results back.

Several anti-creationists have made a hobby out of attacking creationists. Their best efforts, however, have generally failed. For example, see: Sanford 2013 Critic ignores reality of Genetic Entropy: the author of a landmark book on genomic decay responds to unsustainable criticisms creation.com 7 Mar 2013. Price, Carter, and Sanford 2020, Responding to supposed refutations of genetic entropy from the ‘experts’, creation.com, 1 Dec 2020. Unperturbed, "Gutsick Gibbon" has recently tried to discredit Dr Jeffrey Tomkins and his work on human-chimp genetic similarities: "80% Chimpanzee" | The Bogus Creationism of Jeffery Tomkins" 26 May 2023 youtube.com/watch?v=QtTHlqhRQi0. In my analysis of her analysis, I note several flaws in her logic. Note, however, that I deliberately ignored several of her main objections. This was not because I do not have answers, mind you, but because I wanted to focus on the most salient questions. Ignored were questions about why God would have included all the chimp-like non-coding DNA when he made humans and questions about properly weighting samples. The most recent comparison I am aware of claimed 96.6% similarity between humans and chimps: Seaman and Buggs 2020 FluentDNA: nucleotide visualization of whole genomes, annotations, and alignments, Frontiers in Genetics 30;11:292. This comes from the laboratory of Richard Buggs. This is much higher than Tomkins' estimates, that, with one exception, are generally in the 80s. However, I know the first author on that paper, so I called him up to discuss his methods. Sure enough, he used entirely different methodology than earlier work from that same laboratory (which arrived at an estimate of ~85%). To reach the higher percentage similarity, they cut out everything humans and chimps do not share, including the centromeres, telomeres, copy number variations of many annotated genes, and hundreds of thousands of small insertions and deletions that must be included to align the two genomes. This "apples to apples" comparison is fine, as long as everybody acknowledges that the true similarity is necessarily less than 96.6%. Yet, if the percent similarity is much less than 99%, there is no way, mathematically, to explain how so many millions of difference arose in the (imagined) 6.5 million years since our last common ancestor.

Dr Rob outlines three aspects of genetics that tell us that, scientifically, the human species is doomed to eventual extinction. These include the rate of mutation accumulation in our population over time, the inability of natural selection to remove most of those mutations, and the sheer number of children that would be required to remove the mutations, given perfect selection. These all argue that there is no hope, collectively, in any evolutionary process. Thus, biblically, the only hope for us individually is through belief in Jesus.

Dr Rob discusses a fundamental aspect of neo-Darwinism (Fisher's Theorem of Natural Selection) and how it fails mathematically. First postulated in 1930, Fisher's idea was promoted as something as firm and settled as the 2nd Law. Problem is, he made several incorrect assumptions that invalidate the whole thing. When you add realistic mutations to the scenario (e.g., Basener and Sanford's 'Fisher's Theorem of Natural Selection with Mutations'), you see that the net trajectory of evolution is downward. Why did it take 90 years to figure this out?

Dr Rob waxes eloquent about some amazing new revelations involving DNA damage repair systems. Researchers recently turned AI onto the human genome, probing the genes and gene systems that are involved in maintaining and repairing DNA. The results shocked everyone. Many more genes that anyone thought are required, and entire new repair systems were discovered. So what came first, DNA or the amazing repair systems required to maintain DNA that are, in turn, coded into DNA? The point is that these systems are absolutely necessary for living things, yet they are also incredibly complicated. They would never be expected to arise without help, but without them the entire DNA system (not just the code, but the DNA itself) could never exist. Evolution, in this case, simply fails to explain much of anything. Links: Kratz et al. 2023. A multi-scale map of protein assemblies in the DNA damage response.

Everybody loves genealogy, but we are severely limited in what we can know about our family histories. There are two main reasons for this. First, family records only go back so far. Even the longest family trees can't go back thousands of years. Second, personal genetics testing can only tell you who your closest relatives are. Yes, genetics can tell you what population you came from, but that is a matter of statistics, not documentation. This is not a problem for belief in the Bible. Adam and Eve are still the (sole) ancestors of everyone who has ever lived, it's just that you cannot prove it with what we have available to us today.

Science advances in fits and starts, and it sometimes takes a detour onto a dead-end road. Bacteria represent one of those roads. Studying bacteria gave us a sense that we could easily figure out biology, that there was a direct connection between genes and behavior, and that life was simple. Granted, there was no other way to get started, but the study of bacteria slowed down our understanding of higher organisms in many ways. From the 'one gene, one enzyme' hypothesis to the thought that living systems can be reduced to a binary decision tree, many things about bacteria misled us and prevented science from seeing that the majority of the information in the genomes of higher organisms is in the non-coding DNA.

Genetic engineering is a controversial topic. From vaccines to fetal cells to transhumanism, the debate rages. Yet, there are certain aspects to genetic engineering that are demonstrably good. How are we supposed to make heads or tails of this new technology, especially since it is impacting every aspect of our lives? I thought that a simple explanation (at least, as simple as I could make it!) of the things I did while earning my PhD could help increase our understanding. I, as a conservative Christian, made the 'frankenfish'. I stole the genes for the bright green and red fluorescent proteins in corals, engineered them into bacteria, then into fish. There is nothing inherently difficult in what I did, but there were a LOT of steps. Perhaps, after this explanation, we can have a more civil discussion on the pros and cons.

We are approaching the 100th anniversary of the Scopes "Monkey Trial". Dr Rob was in the neighborhood, so he stopped by the Rhea County Courthouse in Dayton, TN to tell the part of the story most people have never heard. This was the first time evolution was put on 'trial' in a US courtroom and it pitted two of the greatest orators of the 20th century against each other: William Jennings Bryan for the prosecution and Clarence Darrow for the defense. Bryan, the Christian anti-evolutionist, gave a weak performance. Darrow, the anti-theistic evolutionist, made Bryan, and thus by proxy, cultural Christianity, look foolish. Put yourself in the shoes of person living in 1925. Which side would you have chosen? Notes and links: Carter R, Scopes at 100: The “monkey trial” shaped an entire century, Creation.com, 25 Aug 2020.

Given the biblical accounts of Creation and the Flood, can we draw any conclusions about what we would expect in genetics? That depends on status of the species in question (e.g., 'clean' vs 'unclean and 'on the Ark' vs 'not on the Ark'), its population history, the amount of created diversity initially engineered into that species/kind, difference in mutation rates and DNA repair systems, and things like that. In the end, no, we cannot make many direct predictions, yet much of the genetic data and observations still point straight to the Bible. The biblical model is expansive enough to take in a range of observations. Notes and links: Tallulah Gorge Orphan Brigade Park Jeanson N. 2015.
