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.

I learned a lot by watching great lectures from Access Research Network. Their YouTube channel is here. 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“.

Stephen C. Meyer lectures on intelligent design and the origin of life

Leave a comment

A MUST-SEE lecture based on Dr. Stephen C. Meyer’s book “Signature in the Cell“. One of my favorite 6 arguments for a Creator and Designer is the origin of the simplest replicating living system. When you look into the cell, what you’ll find is carefully sequenced components that for complex structures, like proteins. In this lecture, you’ll learn all about this “biological information”.

I highly recommend watching the lecture, and looking at the slides. The quality of the video and the content is first class. There is some Q&A (9 minutes) at the end of the lecture.

Topics:

  • intelligent design is concerned with measuring the information-creating capabilities of natural forces like mutation and selection
  • Darwinists think that random mutations and natural selection can explain the origin and diversification of living systems
  • Darwinian mechanisms are capable of explaining small-scale adaptive changes within types of organisms
  • but there is skepticism, even among naturalists, that Darwinian mechanisms can explain the origin of animal designs
  • even if you concede that Darwinism can account for all of the basic animal body plans, there is still the problem of life’s origin
  • can Darwinian mechanisms explain the origin of the first life? Is there a good naturalistic hypothesis to explain it?
  • there are at least two places in the history of life where new information is needed: origin of life, and Cambrian explosion
  • overview of the structure of DNA and protein synthesis (he has helpful pictures and he uses the snap lock blocks, too)
  • the DNA molecule is composed of a sequence of bases that code for proteins, and the sequence is carefully selected to have biological function
  • meaningful sequences of things like computer code, English sentences, etc. require an adequate cause
  • it is very hard to arrive at a meaningful sequence of a non-trivial length by randomly picking symbols/letters
  • although any random sequence of letters is improbable, the vast majority of sequences are gibberish/non-compiling code
  • similarly, most random sequences of amino acids are lab-proven (Doug Axe’s work) to be non-functional gibberish
  • the research showing this was conducted at Cambridge University and published in the Journal of Molecular Biology
  • so, random mutation cannot explain the origin of the first living cell
  • however, even natural selection coupled with random mutation cannot explain the first living cell
  • there must already be replication in order for mutation and selection to work, so they can’t explain the first replicator
  • but the origin of life is the origin of the first replicator – there is no replication prior to the first replicator
  • the information in the first replicator cannot be explained by law, such as by chemical bonding affinities
  • the amino acids are attached like magnetic letters on a refrigerator
  • the magnetic force sticks the letters ON the fridge, but they don’t determine the specific sequence of the letters
  • if laws did determine the sequence of letters, then the sequences would be repetitive
  • the three materialist explanations – chance alone, chance and law, law alone – are not adequate to explain the effect
  • the best explanation is that an intelligent cause is responsible for the biological explanation in the first replicator
  • we know that intelligent causes can produce functional sequences of information, e.g. – English, Java code
  • the structure and design of DNA matches up nicely with the design patterns used by software engineers (like WK!)

There are some very good tips in this lecture so that you will be able to explain intelligent design to others in simple ways, using everyday household items and children’s toys to symbolize the amino acids, proteins, sugar phosphate backbones, etc.

Proteins are constructed from a sequence of amino acids:

A sequence of amino acids forming a protein
A sequence of amino acids forming a protein

Proteins sticking onto the double helix structure of DNA:

Some proteins sticking onto the sugar phosphate backbone
Some proteins sticking onto the sugar phosphate backbone

I highly, highly recommend this lecture. You will be delighted and you will learn something.

Here is an article that gives a general overview of how intelligent design challenges. If you want to read something more detailed about the material that he is covering in the lecture above related to the origin of life, there is a pretty good article here.

There is a good breakdown of some of the slides with helpful flow charts here on Uncommon Descent.

Positive arguments for Christian theism

Polemics

Can atheists condemn slavery as immoral? Do atheists believe that slavery is wrong?

3 Comments

Note: For a Christian response to the complaint that the Bible doesn’t condemn slavery, see this article and this article for slavery in the Old Testament, and this article for slavery in the New Testament. These are all by Christian philosopher Paul Copan. You can watch a lecture with Paul Copan on the slavery challenge here, and buy a book where he answers the challenge in more detail. There is also a good debate on whether the Bible condones slavery here, featuring David Instone-Brewer and Robert Price. My post is not a formal logical essay on this issue, it is more that I am outraged that atheists, who cannot even rationally ground objective morality, insist on criticizing the morality of the Bible. I think that atheists who are serious about finding the truth about these issues should check out those links, if they are interested in getting to the truth of these matters.

In other posts, I’ve argued that without an objective moral standard of what is right and wrong, any judgments about right and wrong are just individual opinions. So, when an atheist says slavery is wrong, what he really means is that he thinks slavery is wrong for him, in the same way that he thinks that,say, that chocolate ice cream is right for him. He isn’t saying what is wrong objectively, because on atheism there are no objective moral rules or duties. He is speaking for himself: “I wouldn’t own a slave, just like I wouldn’t eat broccoli – because it’s yucky!”. But he has no rational argument against other people owning slaves in other times and places, because their justification for owning slaves is the same as his justification for not owning slaves : personal preference and cultural conventions.

So do atheists oppose slavery? Do they believe in an objective human right to liberty? Well, there are no objective human rights of any kind on atheism. Human beings are just accidents in an accidental universe, and collections of atoms do not mysteriously accrue “rights”. There is no natural right to liberty on atheism. Now consider abortion, which is favored by most atheists. Like slavery, abortion declares an entire class of human beings as non-persons in order to justify preserving their own happiness and prosperity by means of violence. That’s exactly what slavery does, except abortion is worse than slavery, because you actually kill the person you are declaring as a non-person instead of just imprisoning them.

So how many atheists have this pro-abortion view that it is OK to declare unborn children  as non-persons so they can kill them?

Well, according to Gallup, the “non-religious” are the group most likely to support abortion. In fact, 68% favor legalized abortion, compared to only 19% who oppose it.

Take a look at the Gallup poll data from 2012:

Atheists are OK with the strong killing the weak
Most atheists are OK with the strong killing the weak

The Gallup numbers might actually be low, because “No religion” might include people who are spiritual, but not religious. But what about atheists alone?

As a group, atheists tend to be among the most radical supporters of legalized abortion. The Secular Census of 2012 found that 97% of atheists vote for abortion. There are almost no pro-life atheists. Why is it that atheists look at unborn children and think it’s OK to kill them? Well, let’s see what atheists scholars think about morality, and from that we’ll find out why they think abortion is morally permissible.

Atheist scholars think morality is nonsense

Atheist William Provine says atheists have no free will, no moral accountability and no moral significance:

Let me summarize my views on what modern evolutionary biology tells us loud and clear — and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death. When I die, I am absolutely certain that I am going to be dead. That’s the end of me. There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will for humans, either.

Atheists Michael Ruse says atheists have no objective moral standards:

The position of the modern evolutionist is that humans have an awareness of morality because such an awareness of biological worth. Morality is a biological adaptation no less than are hands and feet and teeth. Considered as a rationally justifiable set of claims about an objective something, ethics is illusory. I appreciate when someone says, ‘Love thy neighbor as thyself,’ they think they are referring above and beyond themselves. Nevertheless, such reference is truly without foundation. Morality is just an aid to survival and reproduction, . . . and any deeper meaning is illusory.(Michael Ruse, “Evolutionary Theory and Christian Ethics,” in The Darwinian Paradigm (London: Routledge, 1989), pp. 262-269).

Atheist Richard Dawkins says atheists have no objective moral standards:

In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, or any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind, pitiless indifference… DNA neither knows nor cares. DNA just is. And we dance to its music. (Richard Dawkins, River Out of Eden: A Darwinian View of Life (1995))

Most atheists are like this – although some affirm objective morality, without really having a rational basis for it. In general though, when atheists use moral language to condemn God, the Bible, or Christians, it’s very important to understand that it is just theater. They are trying to use words that describe realities that they do not even believe in, usually with the goal of getting you to stop judging them for their own sin. I blogged about two examples of this before – Richard Carrier and Michael Shermer.

Let’s take a closer look at Richard Dawkins’ statement that there is “no evil and no good”.

Richard Dawkins and morality

Here’s Richard Dawkins’ view of abortion:

Richard Dawkins explains morality on atheism
Richard Dawkins explains morality on atheism

But wait! He goes even further than mere abortion:

Dawkins believes in Darwinian evolution. Survival of the fittest. The strong kill the weak. Where is protection for the unborn in that narrative?

Richard Dawkins even advocates for adultery.

So, what Dawkins really believes is that morality is nonsense. But in order to get you to stop condemning abortion, adultery, infanticide and a whole host of other atheistic misbehaviors, he will try to condemn you using moral language to stop you from making moral judgments. But the goal here is to intimidate you into not judging. By his own words, he thinks that the whole notion of objective moral values and objective moral duties is just nonsense.

Who does oppose slavery?

How did slavery end?

Dinesh D’Souza explains:

Slavery was mostly eradicated from Western civilization–then called Christendom–between the fourth and the tenth century. The Greco-Roman institution of slavery gave way to serfdom. Now serfdom has its problems but at least the serf is not a “human tool” and cannot be bought and sold like property. So slavery was ended twice in Western civilization, first in the medieval era and then again in the modern era.

In the American South, Christianity proved to be the solace of the oppressed. As historian Eugene Genovese documents in Roll, Jordan, Roll, when black slaves sought to find dignity during the dark night of slavery, they didn’t turn to Marcus Aurelius or David Hume; they turned to the Bible. When they sought hope and inspiration for liberation, they found it not in Voltaire or D’Holbach but in the Book of Exodus.

The anti-slavery movements led by Wilberforce in England and abolitionists in America were dominated by Christians. These believers reasoned that since we are all created equal in the eyes of God, no one has the right to rule another without consent. This is the moral basis not only of anti-slavery but also of democracy.

And, in fact, you can see Christians pushing the culture hard against abortion today, just as we did with slavery. We also oppose frivolous divorce, and redefining marriage in a way that normalizes removing mothers and/or fathers away from their children. Defending the weak is what we do.
