Yet more on high quality ignorance.

Asking the Right Questions: My Visit to Brown University and MIT -
Brian Miller

This past week I had the privilege of speaking at Brown University and MIT about the evidence for design in nature. I covered the topics of fine-tuning in the laws of physics, the thermodynamics of the origin of life, and biological information. I was deeply impressed by the students at both schools, particularly in their responses to my presentations.

Several of the participants had never heard the evidence for design, so they were visibly struck by its weight and the enormity of its implications. The questions were particularly thoughtful, sincere, and relevant. They were also very common in such discussions, so I thought I would address each of them.

In relation to the fine-tuning of the universe, two issues came up, as they almost always do.

Question: If the laws of physics were different, could not some other type of life have evolved in those alternative conditions?

Response: Many of the laws of physics have to be fantastically fine-tuned for a diversity of atoms to appear in sufficient abundance for any type of life. For instance, if the masses of the protons and neutrons were not just right, we would not have any of the atoms, such as carbon, needed for any type of life. Or, if gravity were not correctly set, planets would never have formed. Without planets, no type of life would have been possible.

Question: Does not the fact that we are here to observe the universe mean that the universe had to have the needed parameters for life to exist? Moreover, if a multiverse exists consisting of an infinite number of universes, we could simply have had the good fortune of ending up in the universe with the required properties.

Response: To better understand the questions, imagine the cousin of a state lottery commissioner winning the lottery twenty years in a row. The police then visit the commissioner and accuse him of wrongdoing, since the odds of a given person winning that many times is so fantastically low. The commissioner responds that we could be living in a multiverse with countless numbers of lotteries happening on planets in different universes at the same time. We just happen to live in the right universe where his cousin won so many times. In addition, if he had not won that often, we would not be having this conversation. Clearly, the police would not be satisfied with that explanation. In the same way, the fact that so many parameters are correct for the specific goal of supporting intelligent life points to design. Moreover, every theory proposed to justify the multiverse has itself to be fine-tuned to generate the correct variety of universes. The fine-tuning cannot be escaped.

In the portion of my presentations dealing with the origin of life, I addressed the fact that nature always tends towards high entropy (disorder) and low energy. However, life is both low entropy (highly ordered) and high energy. No natural process would ever take the basic building blocks of life and form a cell, since nature would have to move in the opposite direction from how it always proceeds. In response, I received another standard question.

Question: Cannot a system move from higher to lower entropy locally, if the surrounding environment increases in entropy to compensate for the local change?

Response: A system can only move to lower entropy if the process is exothermic, which means it gives off heat. In that case, the heat that enters the surrounding environment increases the entropy more than the local entropy decreases. However, the formation of a cell corresponds to a decrease in entropy, and in endothermic processes, heat is absorbed. Therefore, both the local system and the surrounding environment go to lower entropy, which is physically impossible.

In the last part of my talk I discussed how the information in the cell points to intelligent design. I received this common question.

Question: Do people not naturally tend to misidentify design in nature, such as seeing a bunny in a cloud? Might we similarly be mistaken in identifying design in the cell?

Response: People might misidentify design, when the evidence is ambiguous. However, when they see a pattern such as Mount Rushmore, they are always correct in inferring design. The amount of information in the simplest possible cell demonstrates the specificity and the level of intentionality seen in Mount Rushmore, not a cloud bunny. Therefore, the conclusion of design is equally valid.

The students commented that they very much enjoyed the discussion, since they never hear the design perspective. And the vast majority wished to stay connected with the sponsoring groups for future conversations. If only all academics could learn to ask the right questions and demonstrate such open mindedness and such a desire for truth.

Yet another Darwinian just so story?

New Skull-Hole Study Is No Evidence for Evolution
Jonathan Witt

A Science Daily headline exclaims, “Human skull evolved along with two-legged walking, study confirms.” Actually, the study confirmed no such thing. The headline is a pro-evolution gloss unwarranted by the findings.

They were reporting the publication of a scholarly paper in the Journal of Human Evolution. The paper itself waits until the first sentence of the Abstract to start overselling the evolutionary implications: “A more anteriorly positioned foramen magnum evolved in concert with bipedalism at least four times within Mammalia.” The paper doesn’t so much fail to show this; it never seriously attempts to do so. Its aims are elsewhere.

The study looked at various bipedal mammals, compared them to some quadruped relatives, and found that the foramen magnum — the hole for the spinal column in the base of the skull — tends to sit farther forward on the bipeds.

The findings aren’t revolutionary. They confirm a longstanding view. But if they hold up, they will give fossil hunters an improved diagnostic for deciding if a mammalian fossil skull was from a biped.

That’s interesting and useful, but it’s not evidence of evolution. That is the case for multiple reasons.

Engineering Logic vs. Darwinian Illogic

Having the foramen magnum closer to the front of the skull’s base makes good engineering sense in the case of mammalian bipeds. The features, in other words, appear to come as a matched set for good design reasons.

The matched set finding isn’t weird-world engineering either. The matched set phenomenon is commonplace in engineering. Bicycles have one kind of axle and four-wheeled vehicles another. On a car or wagon, those long axle shafts and the four-wheel architecture appear together because they make engineering sense.

There are also good engineering reasons to doubt the Darwinian evolution of quadruped to biped. Vast oceans of reduced fitness lie between a well-integrated quadruped design and a well-integrated biped design. Ann Gauger goes into some detail about this on pages 21-25 of Science and Human Origins. Here, suffice to say that evolving one tiny step at a time from quadruped to biped — gradually re-engineering all the numerous integrated details by random mutations — would force our aspiring quadruped to spend many generations distinctly less fit than he was before.

That’s a problem for evolution because natural selection doesn’t back less functional cripples generation after generation for the mere hope of a glorious upright and striding biped somewhere in the distant future. Natural selection is all about the here and now.

Finally, the study doesn’t describe a finely graded series of fossils moving from quadruped to various intermediates to bipeds. The study is all about the two distinct groups — biped and quadruped.

As for the misleading claims that the study confirms evolution, there is a quick fix at least for the opening words of the Science Daily article. The fix involves a deletion of information rather than the creation of new information (fitting since Darwinism’s verified success stories involve loss of biological information).

In this case, just cut the first three words, thus: “The evolution of bipedalism in fossil humans can be detected using a key feature of the skull — a claim that was previously contested but now has been further validated by researchers at Stony Brook University and the University of Texas at Austin.”
