New study: parrots have similar brain mechanisms to humans

OK, it’s a fun Friday post. I guess most of my readers know that I love almost all the birds, and especially parrots. I have owned parrots most of my life, and want to get more, too. I also like to feed the wild birds who come to visit my house. One reason I like them so much is that they are very intelligent and obviously designed by a very clever engineer.

First, let me explain what convergence is, then we’ll look at a recent peer-reviewed scientific publication.

We have to start this Science Daily post with the definition of convergence in biology.

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

It is the opposite of divergent evolution, where related species evolve different traits.

On a molecular level, this can happen due to random mutation unrelated to adaptive changes; see long branch attraction. In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats.

All four serve the same function and are similar in structure, but each evolved independently.

So, naturalists say that if two organisms have traits that are similar, it must mean that the trait evolved once in their ancestors, and then the modern species inherited the trait from those ancestors. If evolution is true, the only mechanism they have to develop traits shared by two organisms is mutation and selection. The problems occur when two organisms share similar traits, but they have no recent common ancestor, and no recent shared evolutionary history of mutation and selection.

Here’s the latest study from the New Scientist:

To learn more how these birds’ brains develop, Mello and his team compared the genome of the blue-fronted Amazon parrot with that of 30 other birds. They found that regions of the parrot genome that regulate when and how genes for brain development are turned on are the same as those found in humans. These so-called ultra-conserved elements evolved in both species at different times, but with similar results.

Well, parrots and humans are completely different creatures, with no recent evolutionary history, and no recent common ancestors. So, if these changes are due to evolution, then we should see them in the very very very distance common ancestor shared by birds and humans. But then shouldn’t they be in all the other animals who descend from that very very very distant common ancestor to?

Watch this:

I’ll tell you what the real explanation is: the real explanation is that God created birds and humans. And, like a clever engineer, he re-used components that produced the behavior he wanted in his birds and his humans. We know how this works, because this is how intelligent agents write code today. Why do we need a naturalistic theory that requires magic to work, when we have a simple explanation that we can  observe every time someone writes a blog post, or some code, or anything with information in it?

Anyway, however you feel about that, try to be kind to birds, as they are much smarter and more sensitive than most people think. Put out some bird feeders in the yard, if you don’t have an outdoor cat. And if you do have a cat, then why not put a bell on it, or keep it indoors?

Stephen C. Meyer and Marcus Ross lecture on the Cambrian explosion

Cambrian Explosion
Cambrian Explosion

Access Research Network is a group that produces recordings  of lectures and debates related to intelligent design. I noticed that on their Youtube channel they are releasing some of their older lectures and debates for FREE. So I decided to write a summary of one that I really like on the Cambrian explosion. This lecture features Dr. Stephen C. Meyer and Dr. Marcus Ross.

The lecture is about two hours. There are really nice slides with lots of illustrations to help you understand what the speakers are saying, even if you are not a scientist.

Here is a summary of the lecture from ARN:

The Cambrian explosion is a term often heard in origins debates, but seldom completely understood by the non-specialist. This lecture by Meyer and Ross is one of the best overviews available on the topic and clearly presents in verbal and pictorial summary the latest fossil data (including the recent finds from Chengjiang China). This lecture is based on a paper recently published by Meyer, Ross, Nelson and Chien “The Cambrian Explosion: Biology’s Big Bang” in Darwinism, Design and Public Education(2003, Michigan State University Press). This 80-page article includes 127 references and the book includes two additional appendices with 63 references documenting the current state of knowledge on the Cambrian explosion data.

The term Cambrian explosion describes the geologically sudden appearance of animals in the fossil record during the Cambrian period of geologic time. During this event, at least nineteen, and perhaps as many as thirty-five (of forty total) phyla made their first appearance on earth. Phyla constitute the highest biological categories in the animal kingdom, with each phylum exhibiting a unique architecture, blueprint, or structural body plan. The word explosion is used to communicate that fact that these life forms appear in an exceedingly narrow window of geologic time (no more than 5 million years). If the standard earth’s history is represented as a 100 yard football field, the Cambrian explosion would represent a four inch section of that field.

For a majority of earth’s life forms to appear so abruptly is completely contrary to the predictions of Neo-Darwinian and Punctuated Equilibrium evolutionary theory, including:

  • the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phylum-level body plans;
  • small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and
  • a steady increase in the morphological distance between organic forms over time and, consequently, an overall steady increase in the number of phyla over time (taking into account factors such as extinction).

After reviewing how the evidence is completely contrary to evolutionary predictions, Meyer and Ross address three common objections: 1) the artifact hypothesis: Is the Cambrian explosion real?; 2) The Vendian Radiation (a late pre-Cambrian multicellular organism); and 3) the deep divergence hypothesis.

Finally Meyer and Ross argue why design is a better scientific explanation for the Cambrian explosion. They argue that this is not an argument from ignorance, but rather the best explanation of the evidence from our knowledge base of the world. We find in the fossil record distinctive features or hallmarks of designed systems, including:

  • a quantum or discontinuous increase in specified complexity or information
  • a top-down pattern of scale diversity
  • the persistence of structural (or “morphological”) disparities between separate organizational systems; and
  • the discrete or novel organizational body plans

When we encounter objects that manifest any of these several features and we know how they arose, we invariably find that a purposeful agent or intelligent designer played a causal role in their origin.

Recorded April 24, 2004. Approximately 2 hours including audience Q&A.

You can get a DVD of the lecture and other great lectures from Access Research Network. I recommend their origin of life lectures – I have watched the ones with Dean Kenyon and Charles Thaxton probably a dozen times each. Speaking as an engineer, you never get tired of seeing engineering principles applied to questions like the origin of life.

If you’d like to see Dr. Meyer defend his views in a debate with someone who reviewed his book about the Cambrian explosion, you can find that in this previous post.

Further study

The Cambrian explosion lecture above is a great intermediate-level lecture and will prepare you to be able to understand Dr. Meyer’s new book “Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design“. The Michigan State University book that Dr. Meyer mentions is called “Darwin, Design and Public Education“. That book is one of the two good collections on intelligent design published by academic university presses, the other one being from Cambridge University Press, and titled “Debating Design: From Darwin to DNA“. If you think this lecture is above your level of understanding, then be sure and check out the shorter and more up-to-date DVD “Darwin’s Dilemma“.

Yale computer science professor David Gelernter expresses doubts about Darwinism

How did life begin?
How did life begin?

I had to learn about David Gelernter when I was doing my Masters in computer science. We studied his book “Mirror Worlds”. A few weeks ago, I blogged about his impressions of the difficulty in forming a simple protein by chance – something that naturalistic mechanisms would have to do in order to avoid intelligent agency as a cause in nature. He found it very unlikely. But there’s more!

Recently, my friend Terrell sent me a video featuring Peter Robinson (who hosts the splendid Uncommon Knowledge show out of Stanford University), and three interesting people. First, there was Dr. Stephen C. Meyer, who is one of my two favorite thinkers. I’ve blogged on his work about the origin of life and the Cambrian explosion here many times. Then, there was Dr. David Berlinski, a secular Jewish professor of mathematics, who has studied origins issues. And then Dr. David Gelernter, who teaches computer science at Yale University, and is a legend in computer science research.

Here’s the video: (H/T Terrell)

Here is an article by Jennifer Kabbany in The College Fix about the video.

She writes about his recent Claremont Review of Books article, as well as the interview above:

In May, the Claremont Review of Books published a column by Gelernter headlined “Giving Up Darwin.” In it, he explained how his readings and discussions of Darwinian evolution and its competing theories, namely intelligent design, have convinced him Darwin had it wrong.

In particular, he cited Stephen Meyer’s 2013 book Darwin’s Doubt as well as The Deniable Darwin by David Berlinski. The professor expanded on his views in an interview with Stanford University’s Hoover Institution that was published last week.

Gelernter stops short of fully embracing intelligent design, both in his essay and during his interview. He said in his interview he sees intelligence in Earth’s design, and has no quarrel with ID proponents, but notes the world a mess, its suffering far outweighs its goodness.

“My argument is with people who dismiss intelligent design without considering, it seems to me — it’s widely dismissed in my world of academia as some sort of theological put up job — it’s an absolutely serious scientific argument,” Gelernter said during his interview. “In fact it’s the first and most obvious and intuitive one that comes to mind. It’s got to be dealt with intellectually.”

I found this part the most interesting, since we are seeing so much intolerance from the secular left, whenever anyone disagrees with their dogma:

Gelernter said he likes many of his colleagues at Yale, that they are his friends, but when he looks at “their intellectual behavior, what they have published — and much more importantly what they tell their students — Darwinism has indeed passed beyond a scientific argument as far as they are concerned. You take your life in your hands to challenge it intellectually. They will destroy you if you challenge it.”

“Now, I haven’t been destroyed, I am not a biologist, and I don’t claim to be an authority on this topic,” Gelernter added, “but what I have seen in their behavior intellectually and at colleges across the West is nothing approaching free speech on this topic. It’s a bitter, fundamental, angry, outraged rejection [of intelligent design], which comes nowhere near scientific or intellectual discussion. I’ve seen that happen again and again.”

Gelernter acknowledges “I am attacking their religion and I don’t blame them for being all head up, it is a big issue for them.”

Dr. Gelernter cited three arguments in his article: the origin of life, and the Cambrian explosion, and genetic entropy. In the first two problems, there is a problem of huge amounts of biological information coming into being . We know that software engineers can write code like that, but there is no Darwinian mechanism for writing that much code and that short of a time period. The third problem shows that Darwinian mechanisms not only don’t produce functional code – they actually break it down.

I’ve covered both of the arguments before on this blog, but if you really want the details, you should pick up the books that convinced Dr. Gelernter: Dr. Stephen C. Meyer’s “Signature in the Cell” and “Darwin’s Doubt”. Each book tackles one of the arguments. For the third problem, a good book is Dr. Michael Behe’s “Darwin Devolves”. Even if you just read something about each book, then you’ll know about the arguments for intelligent causes being the best explanation for the history of life on this planet.

Information Enigma: 21-minute video explains intelligent design

Can random mutation and natural selection create new functional information?
Can random mutation and natural selection create new functional information?

The video is here:

I have read and listened and watched a lot of material on intelligent design, but I have never seen so much value packed into such a short lecture. I really hope you’ll watch this and that it’s helpful to you.

Summary:

  • the big question when discussing the origin of life: where did the information in living systems come from?
  • Until 530 million years ago, the oceans were largely devoid of life
  • In a 10 million year period, many new forms of animal life emerged
  • New biological forms of life require new information
  • the discovery of DNA shows that living systems work because cells have information that allows them to build the components of molecular machines: cell types, proteins, etc.
  • can random mutation and natural selection create new functional information?
  • normally, random mutations tend to degrade the functionality of information, e.g. – randomly changing symbols in an applications code does not usually introduce useful new functions, it usually renders what is there non-functional
  • the majority of possible sequences will NOT have functions, so random mutations will more likely give you non-functional code, rather than functional code
  • example: a bicycle lock  with 4 numbers has many possible sequences for the 4 numbers, and only one of them has unlock functionality, the rest have no functionality
  • if you have lots of time, then you might be able to guess the combination, but if the lock as has 10 billion numbers, and only one combination that unlocks, you can spend your whole life trying to unlock it and won’t succeed
  • how likely is it to arrive at a functional protein or gene by chance? Is it more like the 4-dial lock (can be done with lots of time) or the 10 billion dial lock (amount of time required exceeds the time available)?
  • the probability is LOW because there is only one sequence of numbers that has unlock function
  • consider a short protein of 150 amino acids has 10 to the 195th power possible sequences
  • if many of these sequences of amino acides had biological function, then it might be easier to get to one by random mutation and selection than it is with a lock that only unlocks for ONE sequence
  • how many of the possible sequences have biological function?
  • Thanks to research done by Douglas Axe, we now know that the number of functional amino acid sequences for even a short protein is incredibly small…
  • Axe found that the odds of getting a functional sequence of amino acids that will fold and have biological function is 1 in 10 to the 77th power
  • Is that number too improbable to reach by chance? well, there are 10 to 65th atoms in the entire Milky Way galaxy… so yes, this is a very improbable outcome
  • can random genetic mutations search through all the sequences in order to find the one in 10 to the 77th power one that has biological function? It depends on how much guessers we have and how many guesses we get in the time available
  • even with the entire 3.5 billion year history of life on Earth, only about 10 to the 40th organisms have ever lived, which far smaller fraction of the 10 to the 77th total sequences
  • even with a very fast mutation rate, you would not be able to reach a functional protein even with all that time, and even with all those organisms

I was once having a discussion with a woman about the research that Axe did at the Cambridge University lab. He published four articles in the Journal of Molecular Biology. I held out one of the papers to her and showed her the numbers. She said over and over “I hate the Discovery Institute! I hate the Discovery Institute!” Well, yeah, but you can’t make the Journal of Molecular Biology go away with hating the Discovery Institute. JMB is peer-reviewed, and this was experimental evidence – not a theory, not a hypothesis.

We have been blessed by the Creator and Designer of the universe in this time and place with overwhelming evidence – an abundance of riches. For those who have an open mind, this is what you’ve been waiting for to make your decision. For the naturalists who struggle so mightily to block out the progress of experimental science, they’ll need to shout louder and shut their eyes tighter and push harder to block their ears. Maybe if they keep screaming “Star Trek” and “Star Wars” over and over to themselves, they will be able to ignore the real science a little longer.

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

Christianity and the progress of science
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?
