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

1 Comment

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.

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“.

Commentary

Jennifer Roback Morse on the injustice of the American family court system

Leave a comment

Here is an article by marriage-defender Jennifer Roback Morse about one of the biggest challenges to life-long married love.

Excerpt:

Easy divorce opens the door for an unprecedented amount of government intrusion into ordinary people’s lives. This unacknowledged reality is the subject of Taken Into Custody, by Stephen Baskerville. With penetrating insight, the political scientist exposes the truly breathtaking consequences of no-fault divorce for the expansion of state power and the decline of personal autonomy.

First, no-fault divorce frequently means unilateral divorce: one party wants a divorce against the wishes of the other, who wants to stay married. Kim Basinger dumped Baldwin for no particular reason, unleashed the power of the Los Angeles Family Court system to inflict pain on him and, in the process, inflicted untold damage on their child. Second, the fact that one party wants to remain married means that the divorce has to be enforced. Baldwin wanted to stay married and to continue to be a husband and father. Yet, the coercive and intrusive machinery of the state must be wheeled into action to separate the reluctantly divorced party from the joint assets of the marriage, typically the home and the children.

Third, enforcing the divorce means an unprecedented blurring of the boundaries between public and private life. People under the jurisdiction of family courts can have virtually all of their private lives subject to its scrutiny. If the courts are influenced by feminist ideology, that ideology can extend its reach into every bedroom and kitchen in America. Baldwin ran the gauntlet of divorce industry professionals who have been deeply influenced by the feminist presumptions that the man is always at fault and the woman is always a victim. Thus, the social experiment of no-fault divorce, which most Americans thought was supposed to increase personal liberty, has had the consequence of empowering the state.

Some might think the legacy of no-fault divorce is an example of the law of unintended consequences in operation. That assumes its architects did not intend for unilateral divorce to result in the expansion of the state. But Baskerville makes the case in this book—as well as his 2008 monograph, “The Dangerous Rise of Sexual Politics,” in The Family in America—that at least some of the advocates of changes in family law certainly have intended to expand the power of the state over the private lives of law-abiding citizens.

She explains who is really behind the attempt to destroy marriage, and the answer might shock you.

It’s important for people to understand the real reasons why people are not getting married, so that we can do something to encourage them to marry that really fixes the problem. If you don’t understand the threats that men are seeing with respect to marriage, it might be a good idea to take a look at this essay by Stephen Baskerville, hosted by the Christian Touchstone magazine. It’s a summary of the book that Dr. Morse reviewed. I consider that book “Taken Into Custody” to be a must-read for anyone contemplating marriage.

Shorebird’s beak inspires researchers to design new water collection strategy

The shorebird's beak is more interesting than you might think
The shorebird’s beak is more interesting than you might think

Dr. Fazale Rana of Reasons to Believe tweeted this cool example of biomimetics from Science Daily.

Excerpt:

A UT Arlington engineering professor and his doctoral student have designed a device based on a shorebird’s beak that can accumulate water collected from fog and dew.

The device could provide water in drought-stricken areas of the world or deserts around the globe.

Xin Heng… a doctoral student in Mechanical and Aerospace Engineering, and Cheng Luo, MAE professor, have made a device that can use fog and dew to collect water.

Cheng Luo, professor in the Mechanical & Aerospace Engineering Department, and Xin Heng, PhD candidate in the same College of Engineering department, published “Bioinspired Plate-Based Fog Collectors” in the Aug. 25 edition of ACS’ (American Chemical Society) Applied Materials & Interfaces journal.

The idea began when Heng saw an article that explained the physical mechanism shorebirds use to collect their food — driving food sources into their throats by opening and closing their beaks. Luo said that inspired the team to try to replicate the natural beak in the lab.

“We wanted to see if we could do that first,” Luo said. “When we made the artificial beaks, we saw that multiple water drops were transported by narrow, beak-like glass plates. That made us think of whether we could harvest the water from fog and dew.”

Their experiments were successful. They found out they could harvest about four tablespoons of water in a couple of hours from glass plates that were about 26 centimeters long by 10 centimeters wide.

Now, if we are lifting designs out of nature, then shouldn’t we give honor to God for putting the designs in there in the first place? I really think it’s important to give God credit where due for his clever designs, even if you’re not a big fan of the shorebird. I also think it’s interesting that it’s engineers who made this application of something in nature, not biologists.  Also, I feel I have to mention that the birdy is also cute, which is not insignificant, if you like birds as much as I do.
