New study: Crows capable of analytical reasoning

Aww! Male cockatiel preens his wife’s crest

Melissa Cain Travis who blogs at Hard Core Christianity sent me news of this wonderful, wonderful study of crow intelligence. I love birds SO MUCH, so I have to blog any story that helps my readers to see why they should love birds, too.

First, read the story from Scientific American.

A recent research collaboration has discovered that crows exhibit strong behavioral signs of analogical reasoning — the ability to solve puzzles like “bird is to air as fish is towhat?” Analogical reasoning is considered to be the pinnacle of cognition and it only develops in humans between the ages of three and four.

[The research team] first trained hooded crows on several tasks in which they had to match items that were the same as one another. The crows were presented with a tray containing three cups. The middle cup was covered by a card picturing a color, a shape, or a number of items. The other two side cups were also covered by cards — one the same as and one different from the middle card. The cup under the matching card contained food, but the cup under the nonmatching card was empty. Crows quickly learned to choose the matching card and to do so more quickly from one task to the next.

Then, the critical test was given. Each card now pictured a pair of items. The middle card would display pairs AA or CD, and the two side cards would display pair BB and pair EF. The relation between one pair of items must be appreciated and then applied to a new pair of items to generate the correct answer: the BB card in the case of AA or the EF card in the case of CD. For instance, if the middle card displayed a circle and a cross, then the correct choice would be the side card containing a square and a triangle rather than the side card containing two squares.

Not only could the crows correctly perform this task, but they did so spontaneously, from the very first presentations, without ever being trained to do so.

Now watch this 2-minute video and see if you can find the answers faster than the crow. I was slower than the crow at the beginning, then faster at the end.

Well, are you impressed? I was impressed!!!!!

Now I have an absolutely silly thought to share with you.

I was thinking about these birds and science posts that I put up and the thought occurred to me about what Christians did to demonstrate the existence of God in debates before we knew about the origin of the universe, the cosmic fine-tuning, galactic habitability, stellar habitability, origin of life, biological information, Cambrian explosion, molecular machines, and blah blah blah de blah.

So what would the William Lane Craig of those days do for his five arguments? Well, the fourth argument would still be the resurrection, and the fifth point would still be religious experience. But the first three would be… BIRDS! Argument one would be some parrot who had learned to talk and do tricks. Argument two would be some parrot who was particularly good at flying and hunting. And argument three would be some particularly beautiful bird. And that’s how you would prove the existence of a Creator and Designer before we had telescopes and microscopes to do it with. Pretty sure.

Anyway, that’s my (silly) idea. Birds are so wonderful, I just say silly things about them!

Study: brain of child neglected by mother is smaller and underdeveloped

Dina sent me this article from the UK Daily Mail.

Here is the scan:

Brain scans of 3-year old children: normal vs neglected

Brain scans of 3-year old children: normal vs neglected

Excerpt:

Both of these images are brain scans of a two three-year-old children, but the brain on the left is considerably larger, has fewer spots and less dark areas, compared to the one on the right.

According to neurologists this sizeable difference has one primary cause – the way each child was treated by their mothers.

The child with the larger and more fully developed brain was looked after by its mother – she was constantly responsive to her baby, reported The Sunday Telegraph.

But the child with the shrunken brain was the victim of severe neglect and abuse.

According to research reported by the newspaper, the brain on the right worryingly lacks some of the most fundamental areas present in the image on the left.

The consequences of these deficits are pronounced – the child on the left with the larger brain will be more intelligent and more likely to develop the social ability to empathise with others.

But in contrast, the child with the shrunken brain will be more likely to become addicted to drugs and involved in violent crimes, much more likely to be unemployed and to be dependent on state benefits.

The child is also more likely to develop mental and other serious health problems.

Professor Allan Schore, of UCLA, told The Sunday Telegraph that if a baby is not treated properly in the first two years of life, it can have a fundamental impact on development.

He pointed out that the genes for several aspects of brain function, including intelligence, cannot function.

[…]The study correlates with research released earlier this year that found that children who are given love and affection from their mothers early in life are smarter with a better ability to learn.

The study by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, found school-aged children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress.

The research was the first to show that changes in this critical region of children’s brain anatomy are linked to a mother’s nurturing, Neurosciencenews.com reports.

The research is published online in the Proceedings of the National Academy of Sciences Early Edition.

Lead author Joan L. Luby, MD, professor of child psychiatry, said the study reinforces how important nurturing parents are to a child’s development.

I have a very good feminist non-Christian friend who sometimes comments here. I once asked her about marriage and she said that her skills would be wasting on raising children. I explained to her my view that a mother needs to stay at home with the children, and that is more important work. I expect my future wife to read all kinds of books on child care and to give the child attention, nutrition, exercise and play so that the child will grow up to be an effective Christian. Maybe I need to be clear. I am not going to spend hundreds of thousands per child with just any woman. I need a woman who can produce influential and effective Christians who will engage in the public square. And we do not entrust that job to just anyone. Professional women who are willing to be stay-at-home moms in the first five years of each child’s life.

I expect the woman I marry (if I marry) to have a college degree, and preferably a graduate degree, and a couple of years of employment. Then she has to stay home and invest in those children through the first five years at least. After that she can stay home or work as much as she thinks is beneficial to the family goals of impacting the university, the church and the public square – as well as continuing to raise those children. It’s not a waste of her talent to make the next William Lane Craig, the next Marsha Blackburn, the next Doug Axe, or the next Edith Jones. Even if we only aim for those guys and get decent, hard-working Christians who make a difference using apologetics, that would still be something. The main thing is not to be scared to try to achieve something with the family – if you aim at nothing, you always hit it.

UPDATE: I am linking to a relevant post from Lindsay, a Christian mother who has a graduate degree in biology and was teaching biology before leaving her career to care for her children.

Why are progressives so blithe about pressuring Christians to act like non-Christians?

A great post from Dr. George Yancey explains the worldview behind so many things we hear in the news these days. Here he is responding to the story about the Houston mayor who subpoena’d all the sermons from the Christian pastors in order to chill dissent to her LGBT agenda.

He writes:

I am a sociologist studying anti-Christian attitudes in our society. This brings me to my take that I am qualified to talk about – whether this legal strategy is tied to Christianophobia. There are reasons to believe that this attempt to obtain sermons and other information is part of a larger strategy to stigmatize Christians. Thus, I do not discount the possibility that Christianophobia plays some role in these actions.

However, it is work of another book I wrote a couple of years ago which I think is more relevant. That book is named What Motivates Cultural Progressives. In that book, I documented that cultural progressive activists tend to consider their political opponents to be irrational, religious individuals trying to move our culture backwards. They have little respect for their political opponents. They often express concerns about the ability of religious individuals to have influence on our political system. With this sort of mindset, it is easy to perceive a motivation from Houston officials, if they are cultural progressive activists, to gather sermons and other material in an effort to “expose” the irrationality and intolerance of their political opponents. Whether the documents are relevant to the current court case may be less important to these officials than stopping the efforts of those who would take our culture backwards.

My suggestion is that it is not as much a fear of Christians as it is the fear of the socially conservative culture linked to Christians driving these subpoenas. The lack of respect cultural progressive activists have for their political opponents allow them to rationalize using the legal system to “dig up dirt” on them. In my sample, I found several individuals who did not believe that religious individuals had the right to fully participate in our political progress. A good number of respondents also articulated a belief that religious individuals are brainwashed and cultural conservative political movements have developed due to the manipulation of ignorant Christians by evil leaders. Thus the political claims in this movement are not legitimate claims by people seeking to serve their own social and material interests, but are the result of manipulation whereby they have been persuaded to vote against their own economic and social interest. When we recognize that many cultural progressive activists do not see cultural conservatives as legitimate political players in our governmental system, then the overreaching request make a great deal of sense.

So how should we respond to this?

Well, the answer is that Christians need to take seriously the need to speak and act intelligently when dealing with non-Christians. We need to study apologetics, yes. But we also need to be good at knowing other things – practical things, academic things. We should be able to earn a living and share with others. We should be able to demonstrate sobriety, discipline and chastity. We should be able to explain rationally and evidentially all the moral beliefs that non-Christians find the most objectionable. We should have an interest in current events, economics, law, politics and foreign policy. Etc. We have to be able to out-think our rivals, and win their respect the same way that Joseph won the respect of Pharaoh, and Daniel won the respect of Nebuchadnezzar.

I think it’s interesting that Dr. George Yancey himself is an excellent example of what I am talking about. He is a full professor at the University of North Texas, and has published books with Oxford University Press. If people want to know if it is possible to be a Christian and be intelligent, this is exactly who we need to show them – and who we need to be. We should be working on this! And raising our kids to counteract these perceptions that the secular leftists have of us. Often, the secular leftists are raised in Christian homes, see the anti-intellectualism in popular Christianity firsthand, then head off to university to train as a persecutor. We have to shape up and stop this from happening. We are train our own executioners, because of our laziness, ignorance and cowardice.

How brief was the period in which the Cambrian phyla suddenly appeared?

The Cambrian explosion refers to the sudden appearance of new body plans in the fossil record. ID proponents think that the period is between 5-10 million years at the most. Naturalists want to stretch out the period in which the body plans appear to tens of millions of years. The two sides can’t both be right. What’s the truth?

Evolution News has the answer.

Excerpt:

To establish the length of the most explosive period of innovation within the Cambrian explosion itself, Meyer cites the work of MIT geochronologist Samuel Bowring and his colleagues as well the work of another group led by Smithsonian paleontologist Douglas Erwin. The Bowring-led study showed that (in their words) “the main period of exponential diversification” within the Cambrian lasted “only 5-6 million years” (emphasis added). Meyer explains:

An analysis by MIT geochronologist Samuel Bowring has shown that the main pulse of Cambrian morphological innovation occurred in a sedimentary sequence spanning no more than 6 million years. Yet during this time representatives of at least sixteen completely novel phyla and about thirty classes first appeared in the rock record. In a more recent paper using a slightly different dating scheme, Douglas Erwin and colleagues similarly show that thirteen new phyla appear in a roughly 6-million-year window. (p. 73)

[…][T]ake a look first at the following figure that Bowring and his colleagues included in their definitive 1993 article, published in the journal Science. They use radiometric methods to date the different stages of the Cambrian period, including the crucial Tommotian and Atdabanian stages in which the greatest number of new animal phyla and classes arise. Note that the so-called Manykaian stage of the Cambrian period lasts about 10-14 million years. Note also that the main pulse of morphological innovation didn’t begin during this stage but rather during the Tommotian and Atdabanian — a period that they describe as taking between “5 to 10 million years,” and in a more detailed passage as taking about 5-6 million years.

[…]In the figure above, the Tommotian and Atdabanian stages of the Cambrian period together span only about 5 million years, starting at about 530 and ending about 525 million years ago. Bowring’s figure also depicts the total number of classes and orders present at any given time during the Cambrian period. The biggest increases in morphological innovation occur during the Tommotian and Atdabanian stages. Indeed, during this period the number of known orders nearly quadruples. Moreover, Bowring and his colleagues also make clear that this period corresponds to the main pulse of Cambrian morphological innovation as measured by the number of new phyla and classes that first appear. They note that, while a few groups of animals do arise in the earliest Manykaian stage of the Cambrian, the most rapid period of “exponential increase of diversification,” corresponding to the Tommotian and Atdabanian stages, “lasted only 5 to 6 m.y.”

You can see the figure they are reference in the Evolution News article.

Also, check out these clips that explain the Cambrian explosion:

Part 1:

Part 2:

The first clip features James Valentine, a professor of biology at the University of California who just co-authored a new book on the Cambrian explosion and is not a proponent of intelligent design.

The consensus among scientists regarding the period of time in which the new body plans appear is 5-6 million years. Biologically speaking, that’s a blink of an eye. You aren’t going that kind of complexity and innovation in such a short period of time any more than you can expect to win the lottery by buying 5-6 million tickets when the odds of winning are 1 in a googol (10 to the 100th power – 1, followed by 100 zeroes). You don’t have enough lottery tickets to make winning the lottery likely. Similarly, 5-6 million years is not enough time for naturalistic mechanisms to code brand new body plans from scratch. It would be like trying to research and write a Ph.D thesis during a single lunch hour. It’s just not enough time to produce the amount of information that’s required.

Stephen C. Meyer discusses his book “Darwin’s Doubt” on the Michael Medved show

The new paperback edition of Darwin’s Doubt is now out (June 2014), and has a new epilogue responding to criticisms of the hardcover first edition. If you don’t have the book, now’s the time to grab it.

Here is a radio interview that Dr. Meyer did about the book, courtesy of the Intelligent Design: The Future podcast.

The MP3 file is available for download. (38 minutes)

The description is:

On this episode of ID the Future, the Michael Medved Show welcomes Dr. Stephen Meyer to talk about his new bestselling book, Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design. Listen in as Meyer and Medved discuss the mysteries of the Cambrian explosion and why this phenomenon continues to stump Darwinian evolutionists.

Each week, leading fellows from Discovery Institute will join Michael Medved to talk about the intersection of science and culture. Listen in live online or on your local Medved station, or stay tuned at ID the Future for the weekly podcast.

Topics:

  • Darwinism offers a materialistic account of where humans and animals came from, but is that all human beings are?
  • Darwin was the first to have doubt about his theory of evolution because of the sudden origin if many different animal forms in the Cambrian era
  • The book is about the sudden origin of these animal forms and more generally about how much information is needed to make an animal genome
  • An animal is not just the form or the organs it is also the information to make new proteins and the instructions to make proteins are in the DNA
  • At least 20 new phyla appear suddenly in the Cambrian fossils and the question is what is capable of creating all of that new information
  • Mathematicians and computer scientists are especially likely to doubt evolution as a way of making new features because they know that random changes to the code base of an application are more likely to break things and degrade performance
  • Naturalists have tried to explain the Cambrian explosion as being a case of the transitional fossils being not yet discovered
  • The consensus of science at this time is that there is no known naturalistic explanation for the sudden origin of these animal types
  • Caller: how abrupt are we talking about for the introduction of these new animal forms?
  • Meyer: We can calculate the amount of time that is needed to generate change, and the period of time that is needed to generate new forms of life exceeds the time available
  • Caller: is it possible that meteors, asteroids and comets could transport biological components to the Earth to shorten the development time?
  • Meyer: that’s related to my first book on the origin of the first living cell “Signature in the Cell”, and that life-from-space hypothesis would only get you building blocks, but not the bio-molecules that have the building blocks sequences – it’s the difference between a pile of Scrabble letters and a Shakespearean play – it’s the arranging of the components that is the problem
  • Medved: The book has a lot of endorsements from scientists who are working at good universities and institutions
  • Meyer: the strange thing about exploring the limits of evolution is that you can cite mainstream papers to criticize the Darwinian mechanisms, and then the proponents of Darwinism just assert that no criticism of Darwinian evolution is allowed
  • Caller Greg: are you saying that all the phyla came in during the Cambrian explosion?
  • Meyer: No, of the 26 phyla that we see in the fossil record, 20 come in during the Cambrian explosion
  • Caller Greg: But there are some sponges that existed before the Cambrian explosion, so maybe all the Cambrian phyla came from sponges?
  • Meyer: There are 3 phyla present in the pre-Cambrian but they are not ancestral to the 20 Cambrian phyla, the sponges are very simple – 6-10 cell types, arthropods have 60-90 cell types – you can’t go from sponges to compound eyes in just 5-10 million years
  • Meyer: even the sponges in the pre-Cambrian appear abrutly at the end of the pre-Cambrian
  • Caller Greg: but there are complex worms in the Pre-Cambrian as well, and maybe those are ancestral to the 20 new phyla that appear suddenly in the Cambrian explosion
  • Caller Greg: what you’re saying is that we scientists don’t understand what happened so an intelligence did it
  • Meyer: No, what I am saying is that the Cambrian explosion involves massive amounts of new biological information, and none of the naturalistic Darwinian mechanisms can create that much new information in that short of the time
  • Caller Greg: it’s magic!
  • Meyer: there are two points in the development of life forms where intelligence is needed: the origin of life and the Cambrian explosion, and this is because of the new information that is being added
  • Caller Greg: new information is added by Hox Gene duplication
  • Caller: don’t we have to look a bit more at epistemology when discussing these issues?
  • Meyer: Yes, we have to highlight that many people reject intelligent design because of a pre-supposition of naturalism that prevents them from seeing that intelligence explains anything regardless of the evidence
  • Caller: well if you define evolution as change over time, then evolution happened, and who cares about the details like the origin of life and Cambrian explosion?
  • Meyer: well there are many definitions of evolution: 1) change over time, 2) universal common ancestry, 3) undirected random process can explain the origin of life and the explosion of new animal forms in the fossil record
  • Meyer: I accept 1) and I am skeptical of 2) and 3)
