Is there a smooth pathway from micro-evolution to macro-evolution?

From Luke Nix who blogs at Faithful Thinkers.

Excerpt:

Macroevolutionary changes are a lot of microevolutionary changes, but they are in a specific series that follow a specific pathway. The missing premise in this argument is that the pathway from ancestor to claimed offspring (many generations down the road) is clear of obstacles.

In his book, “The Edge of Evolution” Michael Behe shows that scientists have observed such an obstacle in the lab. The obstacle was not time, it is in the genetic pathway that must be traversed if macroevolutionary changes are to take place in reality. Since an obstacle has been observed, we now have a false premise in the argument. Since there is a false premise, the argument fails. There is a difference between micro- and macro-evolutionary changes. A lot of microevolutionary changes are necessary for macroevolution, but they are not sufficient. The other sufficient condition (a clear genetic pathway) still has yet to be met. Since both sufficient conditions for macroevolution have not been met, it has not been demonstrated. And since changes over time has been demonstrated, there is a need to distinguish between the two. To prevent confusion about what we know to be true and what we don’t, this distinction must be made.

There is only one way that this can be overcome by the naturalist: find a pathway that would be clear by default in nature. Notice that I have added one more piece to the missing premise above: “…clear by default in nature“. I have to add that last qualification because as scientists are looking for a way to overcome this obstacle, they are introducing their own intelligence- fine-tuning the process, then “allowing nature to take its course”. Their conclusion of naturalistic macroevolution will depend on a premise that is founded on intelligence. That would undermine the whole argument for naturalistic (macro)evolution.

This is one of the ways to show that evolution is true – by showing a pathway to macro-evolutionary change in the lab. If people expect me to believe in the grandiose claims of fully naturalistic evolution through a stepwise process, then why can’t I see the pathway myself? If you make the claim that it happened, then I want to see the evidence for the claim.

The Talk Origins speciation FAQ and the problem of citation-bluffing

1 Comment

The thing to be explained by Darwinism (in addition to the origin of life) is how can you get new, different body plans and organ types by the mechanisms of mutation and selection. Everyone admits that you can get cases where animal A mutates in a small way so that it can no longer breed with animal B. That is speciation of a sort, because the animals can no longer breed. But the real question is whether we can generate species with different body plans using these naturalistic Darwinian mechanisms of mutation and selection.

Here are two podcasts featuring Casey Luskin that discuss how much morphological change has really been observed according to research.

Here is the MP3 file from part one. (14 minutes)

Details:

On this episode of ID The Future, Casey Luskin discusses Talk Origins, a resource often used by supporters of Darwinian evolution to refute arguments made by proponents of intelligent design. After taking a closer look, Luskin found FAQs on Talk Origins guilty of citation bluffing, overstated claims, and other misleading tactics. In particular, the Talk Origins FAQ on speciation claims to provide evidence of “observed instances” of new species. On further review, this turns out to be far from the case. Tune in to Luskin as he explains why.

On this episode of ID The Future, Casey Luskin continues his discussion about Talk Origins, a resource often used by supporters of Darwinian evolution to refute arguments made by proponents of intelligent design.

In particular, the Talk Origins FAQ on speciation claims to provide evidence of “observed instances” of new species. On further review, this turns out to be far from the case. Tune in to Luskin as he explains why in this conclusion to a two-part series.

Basically, he takes a look at the details of cases of “speciation” claimed in the Talk Origins FAQ, and finds that the changes are minor changes, and not changes in morphology. This is not the change that we are looking for to support the hypothesis of macro-evolution. In order to become Darwinists, we need to observe change driven by mutations that leads to changes in body plans. And the mutations have to be heritable.

Highly recommended. You’ve got to love the directness of Casey Luskin explaining what needs to be proved and what has been proved. By the way, here is a more detailed written assessment of speciation claims of the Darwinists.

In Asia, questioning Darwinism on scientific grounds is no problem

From Evolution News.

Excerpt:

In Korea, a mainstream publisher of popular and science texts, Book 21 Publishing Group, has brought out an edition of Explore Evolution, a textbook presenting both sides of the evolution debate. The translation was done by a pair of Korean academics, Seung Yup Lee and Eung Bin Kim, whose scientific specialties are respectively in biomimetics and environmental microbiology. Both teach at universities, Sogang and Yonsei, ranked in Korea’s top ten.

Dr. Lee’s research fuels his questions about macroevolution. His work on the amazing “natural design” of the South American Hercules beetle and its humidity-sensing shell was highlighted in Nature. In the Preface to the Korean Explore Evolution, Lee advocates investigating “alternative theories” to undirected Darwinian evolution.

Korea also has its own Research Association for Intelligent Design, with an impressive masthead of biologists, chemists and other scientists at top research institutions. Sogang University in Seoul hosts an Annual Symposium on Intelligent Design. The event has included presentations on William Dembski and Robert Marks’s Law of Conservation of Information and on protein translation as evidence of intelligent design.

China, of course, is Asia’s biggest market for ideas. Illustra Media has had considerable success distributing DVDs of prime ID-related titles there.

[…]Producer and director Lad Allen had Unlocking the Mystery of Life and Privileged Planet dubbed into Cantonese and Mandarin, moving a hundred thousand copies into China via Hong Kong. He estimates that three or four times that many DVDs were illegally pirated and copied.

[…]Illustra has completed a Japanese translation of The Privileged Planet, lip-synced by Japanese actors in Tokyo. But Unlocking the Mystery of Life is Illustra’s most-translated film, with editions in Khmer (Cambodian), Thai, Sri Lankan, and Mongolian as well as a variety of European languages.

On the book-publishing side, Center for Science & Culture senior fellow Paul Chien has been largely responsible for introducing intelligent design to China. A biologist at the University of San Francisco, Chien has translated Phil Johnston’sDarwin on Trial and Michael Behe’s Darwin’s Black Box among other titles.

He recently finished work on Denyse O’Leary’s By Design Or By Chance?, to be followed by Stephen Meyer’s Signature in the Cell.

It’s good that there are still some places left where a person can ask questions about what natural causes can do and what intelligent causes can do.
