Wired Science misleads readers on what Galapagos finches really prove

1 Comment

Here’s the article. (H/T Neil Simpson)

Excerpt:

On one of the Galápagos islands whose finches shaped the theories of a young Charles Darwin, biologists have witnessed that elusive moment when a single species splits in two.

Well, that would be very interesting… if it were true. But whenever I’ve heard these finches mentioned, it turns out that what actually happened is that populations of different kinds of finches increase and decrease in response to changing environmental conditions. No finch’s beak actually changes size! Some finches with beaks more adapted to the environmental conditions survive and leave more offspring than other finches who are not as adapted. When conditions change, the changes in populations reverse themselves and return to equilibrium.

Evolution News explains:

The deeper problem with the Wired Science report is not its perpetuation of the legend of Darwin’s finches, but its false claim that biologists have now “witnessed that elusive moment when a single species splits in two.” This is not what Peter and Rosemary Grant reported in their scientific article in the Proceedings of the National Academy of Sciences. 6

According to the Grants, in 1981 they found an unusually large male medium ground finch (scientific name: G. fortis) on the island of Daphne Major that they labeled 5110. They inferred that it had probably immigrated from the nearby island of Santa Cruz—though they could not be certain. For 28 years, the Grants followed all known descendants of this presumed immigrant, and genetic analysis suggested that after 2002 the descendants of 5110 bred only with each other (and were thus “endogamous”). The inbred group had a distinctive song that may have contributed to its reproductive isolation from other medium ground finches that were in the same area (“sympatric”).

But the Grants did not go so far as to label the inbred descendants a new species. “We treat the endogamous group as an incipient species because it has been reproductively isolated from sympatric G. fortis for three generations and possibly longer.” But an “incipient species” is not the same as a new species. In The Origin of Species, Darwin wrote: “According to my view, varieties are species in the process of formation, or are, as I have called them, incipient species.” 7 But how can we possibly know whether two varieties (or races) are in the process of becoming separate species? Saint Bernards and Chihuahuas are two varieties that cannot interbreed naturally. The Ainu people of northern Japan and the !Kung of southern Africa are separated not only geographically, linguistically, and culturally, but also (for all practical purposes) reproductively. Are dog breeds and human races therefore “incipient species?”

There’s no way we can know, unless we observe varieties becoming separate species at a future date. Designating two reproductively isolated populations “incipient species” is nothing more than a prediction that speciation will eventually occur. It is a far cry from observing the origin of a new species.

Assessing Bart Ehrman’s case against the resurrection of Jesus

10 Comments

Let’s start by listing some of Bart’s debates, and then we can take a look at his argument.

Bart Ehrman’s debates

  1. William Lane Craig vs. Bart Ehrman. The full transcript of the debate is here, so you can follow along with the video.
  2. Mike Licona’s first debate with Ehrman (audio, video).
  3. Ehrman’s debate with Peter Williams on the UK-based Unbelievable radio show.
  4. Ehrman’s debate with Dan Wallace
  5. Ehrman’s second debate with Licona can be ordered here for $10. Review is here.

Here’s William Lane Craig’s opening speech against Bart: (in 12 parts)

Part 1 of 12:

Part 2 of 12:

Bart’s argument

Bart Ehrman has a standard case based on 1) manuscript variants and 2) David Hume’s argument against miracles. Basically, he says that because the massive number of manuscripts contains a massive number of minor disagreements (see below), that the Bible cannot be trusted and therefore we can’t know whether Jesus rose bodily from the dead.

In Ehrman’s debate with Peter Williams on the UK-based Unbelievable radio show, and in Ehrman’s debate with Dan Wallace, Ehrman lists the 4 worst problems caused by the invariants:

  1. the woman caught in adultery (John 7:53-8:11) is a late addition not present in the earliest manuscripts
  2. the long ending of Mark (Mark 16:9-20) is a late addition not present in the earliest manuscripts
  3. Jesus was angry and not compassionate when he healed the leper (Mark 1:41)
  4. that Jesus died apart from God, and not by the grace of God (Hebrews 2:9)

I personally dislike that story in 1), because I think a lot of feminized Christians like it because they do not want to have their happiness diminished by moral judgments. They misunderstand this passage to support self-serving moral relativism and postmodern hedonism. Or worse, anti-capital-punishment. Eww.

This Bible verse is a favorite of all the liberal “Christian” women I’ve met. I’ve noticed that they are terrified of moral judgments and they don’t like to have to do anything for God, like study apologetics. I don’t like that. So I say: throw the girly-verse out! If you want a good verse that shows that Jesus liked women, you should be reading the woman at the well story. Or the women witnesses to the empty tomb.

Regarding 2), I like that long ending because it’s more useful from an apologetics standpoint. So I do care about this invariant, and I just don’t use that ending when I debate. For 3), I prefer angry Jesus to compassionate Jesus. And for 4) I really don’t care. It’s Hebrews! It’s not like it’s Mark or 1 Corinthians 15.

Ehrman’s argument against miracles is really just David Hume’s argument against miracles, which even non-Christian scholars, like John Earman, have defeated at the highest level here:

So, one can easily see that Bart Ehrman’s case is silly and amounts to nothing in a formal debate on the resurrection. If you want to understand why he is selling so many books, just like Dan Brown, you need to understand that people want space to invent a Jesus that they like. Bart gives them that space by fueling their skepticism of traditional Christianity.

Responding to Bart Ehrman with the minimal facts

Bart seems to be under the misapprehension that Christians argue for the resurrection by assuming the whole Bible is inspired. But we don’t. We use a minimal facts case where each fact had to pass a battery of standard historical tests for the genre of historical biography.

We come up with a list of minimal facts like this list:

  • the burial narrative
  • the empty tomb
  • the appearances
  • the early belief in a bodily resurrection

We argue that the bodily resurrection is the best explanation of these facts, and we refute all naturalistic explanations of these minimal facts like these:

  • Jesus wasn’t really dead
  • Someone stole the body
  • The appearances were hallucinations

One other thing that may be of interest is British scholar N.T. Wright’s case for the resurrection, based on the changes introduced in the belief and practice of the first Jewish converts to Christianity.

Further study

For further study of Licona and Ehrman, I would recommend the book “The Case for the Resurrection of Jesus”, by Gary Habermas and Mike Licona on the resurrection, which is the best introductory book you can get on how to argue the minimal facts case.

If you like Lee Strobel’s interviewing style, then you can’t go wrong with this book, “The Case for the Real Jesus” and his earlier book “The Case for Christ”. All the Lee Strobel books are excellent, the best books that a beginner can get – the ground floor of apologetics, so to speak.

If you prefer books featuring debates between opposing scholars, check out William Lane Craig against Gerd Ludemann here, (audio of their re-match is here), William Lane Craig against John Dominic Crossan here, (audio of the debate is here), or N. T. Wright against John Dominic Crossan here, (audio of the debate only is here).

Gary Habermas, (has dual doctorates from Oxford and Michigan State) is also a good source.

He debates a Duke University professor here: (one of my favorites)

Summary of the William Lane Craig vs Christopher Hitchens debate: Does God Exist?

59 Comments

UPDATE: The video of the debate has been posted:

TOPIC: DOES GOD EXIST?

MY NOTES ON THE DEBATE: (WC = William Lane Craig, CH = Christopher Hitchens)

WC opening speech:

Introduction:

WC makes two contentions:
– there are no good arguments for atheism
– there are good arguments for theism

These topics are IRRELEVANT tonight:
– social impact of christianity
– morality of Old Testament passages
– biblical inerrancy
– the debate is whether god (a creator and designer of the universe) exists

1. cosmological argument
– an actually infinite number of past events is impossible
– number of past events must be finite
– therefore universe has a beginning
– the beginning of the universe is confirmed by science –  universe began to exist from nothing
– space, time, matter, energy began at the big bang
– the creation of the universe requires a cause
– the cause is uncaused, timeless, spaceless, powerful
– the cause must be beyond space and time, because it created space and time
– the cause is not physical, because it created all matter and energy
– but there are only two kinds of non-physical cause: abstract objects or minds
– abstract objects don’t cause effects
– therefore must be mind

2. teleological argument
– fine-tuned constants and ratios
– constants not determined by laws of nature
– also, there are arbitrary quantities
– constants and quantities are in narrow range of life-permitting values
– an example: if the weak force were different by 1 in 10 to the 100, then no life
– there are 3 explanations: physical law or chance or design
– not due to law: because constants and quantities are independent of the laws
– not due to chance: the odds are too high for chance
– therefore, due to design
– the atheist response is the world ensemble (multiverse)
– but world ensemble has unobservable universes, no evidence that they exist
– and world ensemble contradicts scientific observations we have today

3. moral argument
– objective moral values are values that exist regardless of what humans think
– objective values are not personal preferences
– objective values are not evolved standards that cultures have depending on time and place
– objective moral values and duties exist
– objective moral values and duties require a moral lawgiver

4. argument from resurrection miracle
– resurrection implies miracle
– miracle implies God
– 3 minimal facts pass the historical tests (early attestation, eyewitness testimony, multiple attestation, etc.)
– minimal fact 1: empty tomb
– minimal fact 2: appearances
– minimal fact 3: early belief in the resurrection
– jewish theology prohibits a dying messiah – messiah is not supposed to die
– jewish theology has a general resurrection of everybody, there is not supposed to be a resurrection of one person
– jewish theology certainly does not predict a single resurrection of the messiah after he dies
– therefore, the belief in the resurrection is unlikely to have been invented
– disciples were willing to die for that belief in the resurrection
– naturalistic explanations don’t work for the 3 minimal facts

5. properly basic belief in god
– religious experience is properly basic
– it’s just like the belief in the external world, grounded in experience
– in the absence of defeaters, those experiences are valid

Conclusion: What CH must do:
– destroy all 5 of WC’s arguments
– erect his own case in its place

CH opening speech:

1. evolution disproves biological design argument
– evolution disproves paley’s argument for a watchmaker

2. god wouldn’t have done it that way
– god wouldn’t have waited that long before the incarnation
– mass extinction and death before Jesus
– god wouldn’t have allowed humans to have almost gone extinct a while back in africa
– why insist that this wasteful and incompetent history of life is for us, that’s a bad design
– the universe is so vast, why would god need so much space, that’s a bad design
– there is too much destruction in the universe, like exploding stars – that’s a bad design
– the heat death of the universe is a bad design
– too many of the other planets don’t support life, that’s a bad design
– the sun is going to become a red giant and incinerate us, that’s a bad design

3. hitchens’ burden of proof
– there is no good reason that supports the existence of god
– all arguments for god can be explained without god
– atheists can’t prove there is no god
– but they can prove there is no good argument for god

4. craig’s scientific arguments don’t go far enough, they only prove deism, not theism
– the scientific arguments don’t prove prayer works
– the scientific arguments don’t prove specific moral teachings of christianity

5. if the laws of physics are so great then miracles shouldn’t be allowed
– good laws and miracles seem to be in contradiction

6. extraordinary claims need extraordinary evidence
– none of craig’s evidence was extraordinary

7. science can change, so craig can’t use the progress of science
– it’s too early for craig to use the big bang and fine-tuning
– the big bang and fine-tuning evidences are too new
– they could be overturned by the progress of science

8. craig wrote in his book that the internal conviction of god’s existence should trump contradicting evidence
– but then he isn’t forming his view based on evidence
– he refuses to let evidence disprove his view
– but then how can atheists be to blame if they don’t believe
– so evidence is not really relevant to accepting theism

9. the progress of science has disproved religion
– christianity taught that earth was center of the universe
– but then cosmology disproved that

Response to the big bang and fine-tuning arguments:
– was there pre-existing material?
– who designed the designer?
