Some leftover questions

 Tony: ―what about the Big Bang? Don’t

Darwinists still have to explain where stuff that

produced life in the first place came from:

galaxies, stars, planets, and life itself from

inorganic matter?‖

 Jay: ―After debating with Darwinists, they

eventually say that the probability of evolution

happening must be ONE, since here we are. How

do we answer that argument?‖

Tony’s Question: The Big Bang

The term is used in both cosmology and biology.

 Cosmology: About 10-15 billion years ago the

universe—including matter, energy and space

itself—came into being out of nothing

 Biology: Biology’s big bang is better known as the

―Cambrian Explosion‖:the geologically sudden

appearance of multi-cellular animals in the fossil

record during the Cambrian period of geologic time,

about 540 million years ago

Big Bang: Cosmology

 Cosmologist Stephen

Hawking (Brief History

of Time) attempts to do

away with a creation

event, via ―imaginary

time,‖ but fails.

 Goal: ―to know the mind

of God‖

 An aside: Hawking’s first

wife an evangelical

 More on this big bang

later

Cambrian Explosion (biology big bang)

 Major body plans of

animals emerge in

relatively brief

geologic time

 Body plans distinct:

no merging of one

into another

 Stasis: these plans

then remain static for

the rest of time until

present

But there must have been another biological

―big bang‖: when life first formed

 Macro-evolution:

how simple already

living things evolved

into more complex

living things (us).

 Origin of Life (OOL):

how simple living

things came into

existence from non- These are two different fields

living chemicals. of study, but related by the

need to explain complexity.

We will be discussing all these issues in more detail

later, but note that a key issue has to do with where

things come from:

• Where do the laws of nature, in operation at the

cosmological big bang come from?

• Where does information contained in every

living cell come from?

Which brings us to Jay’s question

 Isn’t the probability

of evolution

happening equal to

ONE, since here we

are?

Probability Calculations for OOL

 See link at the ARN site by Stephen Meyer:

www.arn.org/docs/meyer/sm_origins.htm



Consider a chain of

amino acids making up a

protein

Most proteins are around 300

amino acids long; let’s consider

one only 100 long.

Since there are 20 amino acids involved

in making real life proteins, to get a specific amino

at a specific site has a probability of 1/20

So, for a 100 chain protein, the probability of a

specific one is (1/20)100 ~ 1/10130: 10 with 130

zeroes after it

Sauer, at MIT, has shown that certain variances

increase this probability up to 1 in 1065

How much time?

3x107 sec/year

Age of universe

15 billion years = 4.5x1017 sec

If 100 amino acids come together randomly

once/sec, then chance of a single specific

protein being formed over the life of the

universe is:

4.5x1017 / 1065 ~ 1/1048

Even if they came together a million times

faster, still gives only 1 chance in 1042

In the 1960s, NASA sponsored research to inform future

astronauts how to recognize even the most rudimentary forms

of life on other worlds – with the conclusion that the simplest

living thing would contain at least 124 proteins of 400 amino

acids each, and would possess a functioning genetic code so

the organism would reproduce true to type.

Within the NAS Workshop (1999) geneticists and cell

biologists reached consensus on the smallest size likely to

be attained by organisms of modern biochemical

complexity. Free-living organisms require a minimum of

250 to 450 proteins along with the genes and ribosomes

necessary for their synthesis.

Combining these odds

 1 chance in 1065 to get a single unique 100 amino

acid chain protein

 But we need at a minimum 250 of them, each

with around 400 amino acids, to get a the smallest

living thing

 Homework: you calculate the odds of that

happening in 15 billion years

 Most OOL researchers have abandoned the idea

of a chance creation of life, and are looking to

areas such as self-organization of chemicals for

new ideas

What is the likelihood that…

 That your car will leak out of your garage?

 That the water in six 20 gallon water jars

would spontaneously turn to excellent

wine?

 That a dead person would rise from the

dead?

 When these happen, what do we call it?

Yet, when something even much less

probable than any of these happens

namely, life on earth, we call it:

The Case for Darwinism

 What is it about Darwinism that makes

some scientists so sure that it is correct?

 First, observe that even the ID community

agrees with the ―fact of evolution‖ at least

as it occurs within a single species

 Resistance to antibiotics

 Cycling of bird beak sizes in Galapagos

The Case for Darwinism-2

 However, ID supporters say that

extrapolation from evolution within a

species to macro-evolution: from single

celled entity to man, is not warranted

 Why do Darwinist feel that macro-

evolution is true?

Fundamental Concept:

Natural Selection

 In a population of living things, there will be a

variation of characteristics

 Some of these will improve reproductive success

 These characteristics are ―naturally selected‖, i.e.,

are favored because they enhance the further

production of offspring

 Dog breeders use this process to produce new

varieties of dogs: in this case it is artificial

selection

Analysis by Phillip Johnson

 Prominent law professor at UC Berkeley

 Recognized as the leader of the ID

movement

 Wrote Darwin on Trial after reading

Dawkin’s Blind Watchmaker while on

sabbatical

Darwinism as a Tautology

 Tautology: An empty or vacuous statement composed of

simpler statements in a fashion that makes it logically true

whether the simpler statements are factually true or false;

for example, the statement Either it will rain tomorrow or

it will not rain tomorrow.

 ―Survival of the Fittest‖ means that the individuals which

produced the most offspring must have been the ones who

produced the most offspring.

 I.e., ―fitness‖ is strictly limited to success in

reproduction

Karl Popper, Philosopher

 Darwinism is not really a scientific theory

because natural selection is an all purpose

explanation that can account for anything,

and therefore explains nothing.

Example: The Peacock

 Which better explains

the existence of the

peacock: natural

selection or design?

Peacock: Natural Selection

 The male’s plumage is

favored by natural

selection because it

attracts the most

favorable females.

 Never mind that it also

makes the male more

vulnerable to predators

because of its

bulkiness

Johnson’s Rejoinder

 Why would natural

selection, which

supposedly formed all

birds from lowly

predecessors, produce a

species whose females lust

for males with life-

threatening decorations?

The peahen should have

developed a preference for

males with sharp talons &

mighty wings.

Evolutionist Futuyma:

 Do the creation scientists really suppose

their Creator saw fit to create a bird that

couldn’t reproduce without six feet of

bulky feathers that make it easy prey for

leopards?

Johnson’s Response

 It seems to me that a

peacock & a peahen

are just the kind of

creatures a whimsical

creator might favor,

but an uncaring

mechanical process

like natural selection

would never permit to

develop.

Remember the ostrich

In Job

Johnson’s Conclusion

 With the weaknesses so noted, why do scientists hold

on to Darwinism?

 The National Academy of Scientists told the Supreme

Court that the most basic characteristic of science is a

―reliance upon naturalistic explanations,‖ as opposed

to ―supernatural means inaccessible to human

understanding.‖ In the latter, unacceptable category

contemporary scientists place not only God but also

any non-material vital force that supposedly drives

evolution in the direction of greater complexity,

consciousness, or whatever.

Johnson Continued....

 If science is to have any explanation for

biological complexity at all it has to make

do with what is left when the unacceptable

has been excluded. Natural selection is the

best of the remaining alternatives, probably

the only alternative.

 But….what is science?

Towards a definition of Science

 Jack Collins,

professor at Covenant

Seminary

 Phillip Johnson

 Thomas Kuhn:

 Paradigm shifts

 Pearcey & Thaxton

 The Soul of Science

Collins: Science & Faith: Friend or Foes?

 A science is a discipline in which one

studies features of the world around us, and

tries to describe his observations

systematically and critically

 There are sciences, not Science!

 Science tends to be a power word

 Connotes unquestionable authority

 Leads to fuzzy thinking

Johnson: Darwin on Trial

In the Arkansas case finding creation-science was

unconstitutional, Judge Overton defined 5

essentials of science:

1. It is guided by natural law

2. It has to be explanatory by reference to natural

law

3. It is testable against the empirical world

4. Its conclusions are tentative—that is not

necessarily the final word

5. It is falsifiable

How do Overton & Collins

Compare?

 Similarities

 OBERVABLE:

 FALSIFIABLE: (CRITCAL THINKING)





 Differences

 NATURAL IS A LOADED TERM (OVERTON)

 COLLINS WOULD ALLOW SUPERNATURAL

Johnson’s critique

 Naturalism is not something about which

Darwinists can afford to be tentative, because

their science is based on it

 Quote: ―Man is the result of a purposeless and

natural process that did not have him in mind.‖

[George Gaylord Simpson, prominent Darwinist]

 Thus, the judge bought into this definition of

science which automatically rules out a Designer

or Creator. (Does this sound familiar, circa

2005?)

Johnson’s Critique-2

 Last 3 points of judge’s definition appear to be

sound: empiricism—focus on data

 However, the data, i.e., the fossil record is

incompatible with Darwin’s predictions

 Rather than gradual changes in intermediate

fossils, we have the Cambrian Explosion

 Thus, naturalism, not empiricism is the real value

for the Darwinist definition of science, otherwise

they would limit their claim to micro-evolution.

Johnson’s Critique-3

Defenders of naturalism must enforce rules of

procedure for science that preclude opposing

points of view. With that accomplished, the next

critical step is to treat ―science‖ as equivalent to

truth and non-science as equivalent to fantasy.

As long as scientific naturalists make the rules,

critics who demand positive evidence for

Darwinism need not be taken seriously. They do

not understand ―how science works.‖

fictional example]

Johnson’s use of Kuhn

 Thomas Kuhn-science historian: author of The Structure

of Scientific Revolutions

 Paradigm, a collection of beliefs shared by scientists, a set

of agreements about how problems are to be understood.

According to Kuhn, paradigms are essential to scientific

inquiry, for "no natural history can be interpreted in the

absence of at least some implicit body of intertwined

theoretical and methodological belief that permits

selection, evaluation, and criticism.‖

 Normal research is directed to the articulation of those

phenomena and theories that the paradigm already

supplies

Paradigm Shift

 Crises are triggered when scientists discover counter-

instances as anomalies in fit between the existing theory

and nature. All crises are resolved in one of three ways.

Normal science can prove capable of handing the crisis-

provoking problem, in which case all returns to "normal."

Alternatively, the problem resists and is labeled, but it is

perceived as resulting from the field's failure to possess

the necessary tools with which to solve it, and so

scientists set it aside for a future generation with more

developed tools. In a few cases, a new candidate for

paradigm emerges, and a battle over its acceptance

ensues. A paradigm shift occurs if the new triumphs

over the old.

Paradigm Shift Examples

 Heliocentric vs geocentric view of earth-sun

system in astronomy (Copernicus)

 Quantum mechanics replaces classical mechanics

in physics (Bohr, Planck, Schrodinger, etc)

 Spontaneous generation replaced by

microorganisms in biology (Pasteur)

 Existence of ether (as medium of light

propagation) eliminated by Michelson-Morley

Is ID an impending paradigm shift?

 May require an old generation of scientific

elites (e.g., members of the National

Academy of Scientists) to literally die off

before a new generation more ID friendly

replaces them.

 ID researchers must follow the data

wherever it leads, even if it means

academic persecution (Dean Kenyon)

Conclusion

 The deck is stacked against ID because of the

―unscientific‖ definition of science in common use

 By ―unscientific‖ I mean that science should follow the

data wherever it leads, even when it violates the current

theories of science

 Given this legal/scientific climate ID will have

significant challenges in making headway

 ID can advance if/when it is able to make

predictions, and offer better explanations of

biological systems than Darwinism does

Pearcey &Thaxton: Trends

 Historicism-the belief that there is no trans-

historical truth and that all knowledge is caught

up in a continual process of historical change.

 A tendency to deny the possibility of objective facts

apart from ideology

 Pragmatic realism-practicing scientists blithely

ignorant of the first trend and assuming facts have

objective meaning

 But within the current paradigm of naturalistic

reductionism

The Past Informs the Future

 In past centuries prominent scientists, such as

Isaac Newton, viewed their work as an outgrowth

of the Christian faith, not a contradiction to it.

 Is the naturalistic materialism that dominates

Western thought a blip in history which will be

someday be replaced by a return to an

understanding of the created universe by Christ as

the Intelligent Designer?

 In the meantime how should Christians address

these issues?

The Words

 In the beginning was

the Word (John 1:1)

[special revelation]



 In the beginning was

the program, the word

encoded in the DNA,

by the Word

[general revelation]
