New study: 90% of species on Earth today originated 100,000 to 200,000 years ago

Christianity and the progress of science

Well, it’s Friday, so I thought we would all benefit from reading about a brand new peer-reviewed study that should be the final nail in the coffin of naturalistic evolution. At least for those with an open mind who are not wedded to the philosophical assumption of naturalism.

Phys.org (which is committed dogmatically to fully naturalistic evolution) reports:

Mark Stoeckle from The Rockefeller University in New York and David Thaler at the University of Basel in Switzerland, who together published findings last week sure to jostle, if not overturn, more than one settled idea about how evolution unfolds.

It is textbook biology, for example, that species with large, far-flung populations—think ants, rats, humans—will become more genetically diverse over time.

But is that true?

“The answer is no,” said Stoeckle, lead author of the study, published in the journal Human Evolution.

For the planet’s 7.6 billion people, 500 million house sparrows, or 100,000 sandpipers, genetic diversity “is about the same,” he told AFP.

The study’s most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.

“This conclusion is very surprising, and I fought against it as hard as I could,” Thaler told AFP.

That reaction is understandable: How does one explain the fact that 90 percent of animal life, genetically speaking, is roughly the same age?

Oh, oh. Pick me, pick me. I know the answer. The answer is that the biological information in living systems was put there by an intelligent agent. You know, the same way that information in books is put there by intelligent agents. And the same way that information in computer code is put there by intelligent agents. And the same way that information in blog posts is put there by intelligent agents. We know what introduces information from our own experience.

Well, what about mutation and selection? Couldn’t they create all this information in a couple hundred thousand years? Well, no. You see, mutation and selection have been tested in the lab to see how much information they can produce over generations and generations. And the conclusion is clear: it is impossible for blind forces to create the amount of information we see in living systems in the short time that is available. In fact, the whole history of the universe is not enough time for evolutionary mechanisms to create the information we have in front of us.

Before we leave the paper reported by Phys.org, here is something about whether we see the gradual emergence of complexity via lots of transitional forms in nature.

Not so much:

[…][A]nother unexpected finding from the study—species have very clear genetic boundaries, and there’s nothing much in between.

“If individuals are stars, then species are galaxies,” said Thaler. “They are compact clusters in the vastness of empty sequence space.”

The absence of “in-between” species is something that also perplexed Darwin, he said.

Indeed. So perplexing.

The evidence we gain from the progress of science is always perplexing to people who assume naturalism, and then try to shoehorn reality to match their religious assumptions. I have an idea. Why don’t we just make science the search for truth, no holds barred? Wouldn’t that be a much better way to do science? Let’s just do science honestly, and stop trying to make it prove things that are comfortable for us.

If the origin of the universe, the fine-tuning of the universe for intelligent life, the origin of the first living system, and the sudden origin of body plans in the Cambrian explosion are impossible to account for on naturalism, then maybe we need to jettison the philosophical assumption of naturalism, and just go where the evidence leads? What’s wrong with that?

Yale University computer science professor takes a look at protein formation probabilities

How did life begin?
How did life begin?

When I was in graduate school, we studied a book called “Mirror Worlds”, authored by famous computer science professor David Gelernter at Yale University. This week, I noticed that Dr. Gelernter had written an article in the prestigious Claremont Review of Books. In his article, he applies his knowledge of computer science to the problem of the origin of life.

Evolution, if it is going to work at all, has to explain the problem of how the basic building blocks of life – proteins – can emerge from non-living matter. It turns out that the problem of the origin of life is essentially a problem of information – of code. If the components of proteins are ordered properly, then the sequence folds up into a protein that has biological function. If the sequence is not good, then just like computer code, it won’t run.

Here’s Dr. Gelernter to explain:

How to make proteins is our first question. Proteins are chains: linear sequences of atom-groups, each bonded to the next. A protein molecule is based on a chain of amino acids; 150 elements is a “modest-sized” chain; the average is 250. Each link is chosen, ordinarily, from one of 20 amino acids. A chain of amino acids is a polypeptide—“peptide” being the type of chemical bond that joins one amino acid to the next. But this chain is only the starting point: chemical forces among the links make parts of the chain twist themselves into helices; others straighten out, and then, sometimes, jackknife repeatedly, like a carpenter’s rule, into flat sheets. Then the whole assemblage folds itself up like a complex sheet of origami paper. And the actual 3-D shape of the resulting molecule is (as I have said) important.

Imagine a 150-element protein as a chain of 150 beads, each bead chosen from 20 varieties. But: only certain chains will work. Only certain bead combinations will form themselves into stable, useful, well-shaped proteins.

So how hard is it to build a useful, well-shaped protein? Can you throw a bunch of amino acids together and assume that you will get something good? Or must you choose each element of the chain with painstaking care? It happens to be very hard to choose the right beads.

Gelernter decides to spot the Darwinist a random sequence of 150 elements. Now the task the Darwinist is to use random mutation to arrive at a sequence of 150 links that has biological function.

[W]hat are the chances that a random 150-link sequence will create such a protein? Nonsense sequences are essentially random. Mutations are random. Make random changes to a random sequence and you get another random sequence. So, close your eyes, make 150 random choices from your 20 bead boxes and string up your beads in the order in which you chose them. What are the odds that you will come up with a useful new protein?

[…]The total count of possible 150-link chains, where each link is chosen separately from 20 amino acids, is 20150. In other words, many. 20150 roughly equals 10195, and there are only 1080 atoms in the universe.

What proportion of these many polypeptides are useful proteins? Douglas Axe did a series of experiments to estimate how many 150-long chains are capable of stable folds—of reaching the final step in the protein-creation process (the folding) and of holding their shapes long enough to be useful. (Axe is a distinguished biologist with five-star breeding: he was a graduate student at Caltech, then joined the Centre for Protein Engineering at Cambridge. The biologists whose work Meyer discusses are mainly first-rate Establishment scientists.) He estimated that, of all 150-link amino acid sequences, 1 in 1074 will be capable of folding into a stable protein. To say that your chances are 1 in 1074 is no different, in practice, from saying that they are zero. It’s not surprising that your chances of hitting a stable protein that performs some useful function, and might therefore play a part in evolution, are even smaller. Axe puts them at 1 in 1077.

In other words: immense is so big, and tiny is so small, that neo-Darwinian evolution is—so far—a dead loss. Try to mutate your way from 150 links of gibberish to a working, useful protein and you are guaranteed to fail. Try it with ten mutations, a thousand, a million—you fail. The odds bury you. It can’t be done.

Keep in mind that you need many, many proteins in order to have even a simple living cell. (And that’s not even considering the problem of organizing the proteins into a system).

So, if you’re a naturalist, then your only resources to explain the origin of life are chance and mutation. As Dr. Gelernter shows, naturalistic explanations won’t work to solve even part of the problem. Not even with a long period of time.  Not even if you use the entire universe as one big primordial soup, and keep trying sequences for the history of the universe. It just isn’t possible to arrive at sequences that have biological function in the time available, using the resources available. The only viable explanation is that there is a computer scientist who wrote the code without using trial and error. Something that ordinary software engineers like myself and Dr. Gelernter do all the time. We know what kind of cause is adequate to explain functioning code.

What happens when we die? Is there a resurrection? Is there a Heaven and a Hell?

Bible study that hits the spot
Bible study that hits the spot

One of the questions that everyone should ask themselves is “what happens to me when I die?” Well, I’m an evangelical Protestant Christian, and I think that view of the world is correct according to logic and evidence. Well, I found an article on this that provides the philosophical theology perspective, from Dr. William Lane Craig. You can’t do better than him.

He writes:

The first and most fundamental truth that we must hold on to is that the biblical hope of immortality is physical, bodily resurrection. I repeat: The biblical hope for immortality is physical, bodily resurrection. The biblical hope is not that the soul will someday be separated from the body and fly off to heaven and be forever with God in heaven in this disembodied existence. That’s actually a very Greek understanding of the afterlife, from the Greek philosophers like Plato, and it’s very different from the Jewish-Hebrew way of thinking of the afterlife. For Jews and for the early Christians alike, the hope of immortality was not the immortality of the soul alone but rather the resurrection of the body. This physical body will be raised from the dead and transformed to immortal life.

He cites 1 Cor 15:20 and Phil 3:20-21 as support.

And do we get our resurrection bodies right away?

Now that raises the next question: When do we receive our resurrection bodies? When do we get our resurrection body? Is it immediately upon death? When we die, do we immediately receive our resurrection body? Well, the answer to that is, no. That idea fails to take seriously the physical nature of the resurrection. The resurrection body is not some different body. It is this body transformed into a glorious, immortal, Spirit-filled, incorruptible form. So if we received our resurrection body immediately upon death, the graves of all the Christians would be empty! There would be no corpses left in the tombs because our resurrection bodies are the transformation of this earthly body. Therefore, the resurrection doesn’t take place immediately upon death. Rather the Scriptures are fairly clear that this takes place at the second coming of Christ, when Christ returns to earth.

He cites 1 Cor 15:21-23, 51-52 for support, as well as 1 Thes 4:13-17.

And what about the time in between death and the second coming of Christ? After all, in Luke 23:39-43, Jesus tells the dying thief who believes in him that he’ll be with Jesus in Paradise that very day:

39 One of the criminals who hung there hurled insults at him: “Aren’t you the Messiah? Save yourself and us!”

40 But the other criminal rebuked him. “Don’t you fear God,” he said, “since you are under the same sentence? 

41 We are punished justly, for we are getting what our deeds deserve. But this man has done nothing wrong.”

42 Then he said, “Jesus, remember me when you come into your kingdom.”

43 Jesus answered him, “Truly I tell you, today you will be with me in paradise.”

Dr. Craig says:

[T]he Bible indicates is that the soul does survive the death of the body. Human death does not mean extinction. Human death is simply the separation of the soul from the body. While the body dies biologically and decays away, the soul continues to exist and continues to live in a disembodied state. In between your death and your resurrection you will exist as a disembodied soul, a soul without a body, in a conscious state.

And he cites Phil 1:21-24, where it talks about how life after death, but before the resurrection, is an improvement, because he will be with Christ, which is “far better”. Those who don’t accept Jesus as Lord and Savior will also have a life after death, but apart from Christ. And they’ll also have a resurrection, but not to eternal life with Christ:

In John 5 there’s a very interesting passage where Jesus speaks about the resurrection, and He says that there will be a resurrection, not only of the righteous dead, but even also of the unrighteous dead. John 5:28-29. Look at this saying by Jesus: “Do not marvel at this. For the hour is coming in which all who are in the graves will hear His voice and come forth, those who have done good to the resurrection of life and those who have done evil to the resurrection of condemnation.” Jesus envisions that all people will be raised from the dead. Those who are believers, the righteous dead, will be raised to the resurrection of life; but the unrighteous dead, those who have rejected God’s grace and His love, will be raised to the resurrection of condemnation.

Dr. Craig also talks about the story of Lazarus, where the rich man, who is not saved, is in Hades, which is the Greek word for the Hebrew word “Sheol”, which you may recognize from the Psalms.

Dr. Craig writes:

When people die, the righteous go to be with Christ, where they will await their resurrection from the dead. The damned go to Hades, where they are in a disembodied state where they await their resurrection to final judgment. Only then are people ushered in to their final state, which is heaven or hell.

I cannot wait until I get my resurrection body. I have a very good idea of what I’d like it to be, too. I think about the resurrection a lot, and really look forward to it. I had a difficult life in many ways. There are things that have not been resolved, like not being married, and being stuck as a virgin! And then there’s the troubles I sometimes have at work, when atheists who are younger and more dedicated than me make me feel inadequate. I was a hard worker in my 20s and 30s, but now in my 40s, I just feel like I would rather be doing things I really care about, and it’s sometimes hard to focus, especially when retirement is just around the corner – around age 50.

Sometimes, I find myself driving home in my beautiful city and state, and I just think, the most important things are not all this prosperity and freedom God blessed me with, but that vertical relationship with God. And I wish I was doing more to really show Jesus that he is Lord of my life. But my hope is that in the end, I will share in his vindication, being clothed in a righteousness that I did not earn myself.
