Title: The Nature of Science, Evolution
1The Nature of Science, Evolution Creationism
- Mike Phillips
- Geology Professor
2Foundations of Science
- Natural Cause The universe behaves in a
predictable way under rules that can be
determined through observation and
experimentation. - Efficient Cause effect follows cause (no Final
Cause, no teleological)
3Foundations of Science
- Uniformity The rules are constant through
space and time. - Parsimony All other things being equal, the
simplest explanation is the best. - Objectivity
4Scientific Explanations
- must be natural
- must be supported by available data
- must be testable falsifiable
- subject to revision or refinement or negation
- should be predictive
5Scientific Explanations
- no arguments from or appeals to authority
- can should build on published work of others
- must be prepared to defend that work as well as
your own
6Theory Hypothesis
- Hypothesis
- a working explanation or educated guess
- competing hypotheses are often investigated
simultaneously - Theory
- the best explanation supported by a preponderance
of the evidence - the best a scientist can hope for
7Should we use biblical explanations instead?
- St. Augustine No. He was concerned that if
Christians asserted that the Bible contradicted
reason and experience with natural phenomena,
potential converts would reject the spiritual
message. - Isaac Newton No. He was concerned that mixing
science and religion would corrupt religion.
(Believed nature operates according to Gods
laws.) - Creationists Yes. (sort of)
8Why give science precedence?
- It works!
- Examples
- Germ theory explains why we get sick
- Plate tectonics theory explains earthquakes
volcanoes predicts economic deposits - Gravity theory allows safe space travel
- Natural selection theory agricultural
development, improved medical practice
(laboratory experimentation germ control),
enhanced pest control
9Why not give the Bible precedence?
- Purpose of Bible
- ethical philosophy (likely)
- scientific resource (unlikely)
- Gap problem
- moves focus away from ethical message
- Bible doesnt always match up with nature
- Gods realm diminished as science grows
- Bible missing most of modern science, medicine,
and technology
10Was the Bible written to be a science text?
- Would the writers have comprehended the material?
- Would the original audience have comprehended the
material? - Is there room for all of the sciences?
- Has it worked well as a science text?
11Is the natural world a better scientific source?
- Direct record
- traces of what happened
- incomplete
- Objective record
- unfiltered
- must be interpreted
- available to all
12Tests for a scientific explanation
- Was the explanation derived from observation?
- Does the explanation rely on natural cause?
- Is it supported by natural data?
- Can the explanation be changed or negated in the
light of new information?
13Is it science?
- Evolution
- derived from observation yes
- natural cause yes
- supported by natural data yes
- change with new data yes
- Creationism
- derived from observation no
- natural cause no
- supported by natural data no
- change with new data no
14Science religion(some perspectives)
- Nature is Gods will, no need to investigate.
- If its in the Bible, thats how it is (was) all
scientific explanations must conform to the
Bible. - Nature operates according to Gods laws, what
science cannot explain is where God has
intervened. - Nature operates according to Gods laws, God
never intervenes. - Nature operates according to natural laws. (no
comment on God) - Nature operates according to natural laws. (there
is no God)

16The Chicago Statement on Biblical Hermeneutics
- We affirm that since God is the author of all
truth, all truths, biblical and extrabiblical,
are consistent and cohere, and that the Bible
speaks truth when it touches on matters
pertaining to nature, history, or anything else.
We further affirm that in some cases
extrabiblical data have value for clarifying what
Scripture teaches, and for prompting correction
of faulty interpretations. - We deny that extrabiblical views ever disprove
the teaching of Scripture or hold priority over
it.
17The Chicago Statement on Biblical Hermeneutics
- We affirm the harmony of special with general
revelation and therefore of biblical teaching
with the facts of nature. - We deny that any genuine scientific facts are
inconsistent with the true meaning of any passage
of Scripture.
18The Chicago Statement on Biblical Hermeneutics
- We affirm that Genesis 1-11 is factual, as is the
rest of the book. - We deny that the teachings of Genesis 1-11 are
mythical and that scientific hypotheses about
earth history or the origin of humanity may be
invoked to overthrow what Scripture teaches about
creation.
19Irreducible Complexity
- A functional system is irreducibly complex if it
contains a multipart subsystem (i.e., a set of
two or more interrelated parts) that cannot be
simplified without destroying the systems basic
function. - Irreducible complexity differs sharply from
another form of complexity that may be called
cumulative complexity. A system is cumulatively
complex if the parts of the system can be
arranged sequentially so that the successive
removal of parts never leads to the complete loss
of function.
20Irreducible Complexity
- To determine whether a system is irreducibly
complex employs two approaches - An empirical analysis of the system that by
removing parts (individually and in groups) and
then by rearranging and adapting remaining parts
determines whether the basic function can be
recovered among those remaining parts. - A conceptual analysis of the system, and
specifically of those parts whose removal renders
the basic function unrecoverable, to demonstrate
that no system with (substantially) fewer parts
exhibits the basic function.

22ICR Tenets of Scientific Creationism
- A Christ-Focused Creation Ministry
- 1. The physical universe of space, time, matter,
and energy has not always existed, but was
supernaturally created by a transcendent personal
Creator who alone has existed from eternity.
23ICR Tenets of Scientific Creationism
- 2. The phenomenon of biological life did not
develop by natural processes from inanimate
systems but was specially and supernaturally
created by the Creator.
24ICR Tenets of Scientific Creationism
- 4. The first human beings did not evolve from an
animal ancestry, but were specially created in
fully human form from the start. Furthermore, the
"spiritual" nature of man (self-image, moral
consciousness, abstract reasoning, language,
will, religious nature, etc.) is itself a
supernaturally created entity distinct from mere
biological life.
25ICR Tenets of Scientific Creationism
- 6. Processes today operate primarily within
fixed natural laws and relatively uniform process
rates but, since these were themselves originally
created and are daily maintained by their
Creator, there is always the possibility of
miraculous intervention in these laws or
processes by their Creator. Evidences for such
intervention should be scrutinized critically,
however, because there must be clear and adequate
reason for any such action on the part of the
Creator.
26ICR Tenets of Scientific Creationism
- 7. The universe and life have somehow been
impaired since the completion of creation, so
that imperfections in structure, disease, aging,
extinctions, and other such phenomena are the
result of "negative" changes in properties and
processes occurring in an originally-perfect
created order.
27ICR Tenets of Scientific Creationism
- 8. Since the universe and its primary components
were created perfect for their purposes in the
beginning by a competent and volitional Creator,
and since the Creator does remain active in this
now-decaying creation, there do exist ultimate
purposes and meanings in the universe.
Teleological considerations, therefore, are
appropriate in scientific studies whenever they
are consistent with the actual data of
observation, and it is reasonable to assume that
the creation presently awaits the consummation of
the Creator's purpose.
28ICR Tenets of Scientific Creationism
- 9. Although people are finite and scientific
data concerning origins are always circumstantial
and incomplete, the human mind (if open to the
possibility of creation) is able to explore the
manifestations of that Creator rationally and
scientifically, and to reach an intelligent
decision regarding one's place in the Creator's
plan.
29Answers in Genesis
- Believing in a relatively 'young Earth' (i.e.,
only a few thousands of years old, which we
accept) is a consequence of accepting the
authority of the Word of God as an infallible
revelation from our omniscient Creator.
30CRS Statement of Belief
- All members must subscribe to the following
statement of belief - 1. The Bible is the written Word of God, and
because it is inspired throughout, all its
assertions are historically and scientifically
true in the original autographs. To the student
of nature this means that the account of origins
in Genesis is a factual presentation of simple
historical truths.
31BCS Creation Manifesto
- While the Bible is not a scientific textbook, it
makes some clear statements which have a direct
bearing on the study of various areas of science,
which provide both frameworks and baselines for
the study of those subjects. The disciplines and
issues dealt with in this section are of crucial
and central importance (though many others could
be cited), and failure to incorporate them into
the relevant disciplines will result in failure
to fully understand the subject, and failure to
glorify God in that area of His creation.

33Biblical Astronomer Credo
- The Biblical Astronomer was originally founded in
1971 as the Tychonian Society, on the premise
that the only absolutely trustworthy information
about the origin and purpose of all that exists
and happens is given by God, our Creator and
Redeemer, in his infallible, preserved word, the
Holy Bible. All scientific endeavor which does
not accept this revelation from on high without
any reservations, literary, philosophical or
whatever, we reject as already condemned in its
unfounded first assumptions.
34Biblical Astronomer Credo
- We believe that the creation was completed in six
twenty-four hour days and that the world is not
older than about six thousand years. We maintain
that the Bible teaches us of an earth that
neither rotates daily nor revolves yearly about
the sun that it is at rest with respect to the
throne of him who called it into existence and
that hence it is absolutely at rest in the
universe.

36From Science Digest (July 1980)
- Johnson's beliefs are firmly grounded in the
Bible. Many verses of the Old Testament imply
that the earth is flat, but there's more to it
than that. According to the New Testament, Jesus
ascended up into heaven. - "The whole point of the Copernican theory is to
get rid of Jesus by saying there is no up and no
down," declares Johnson. "The spinning ball thing
just makes the whole Bible a big joke."

40Age of the Earth observations
- rocks
- sedimentary 1000s of feet thick
- intrusive igneous rocks metamorphic rocks cool
and exposed - unconformities even more rocks are missing
- radiometric dating
- provides actual ages
- age of the sun
- from the rate it is fusing hydrogen
41Age of the Earth 4.5 BYO
- rocks earth is very, very, very old
- radiometric dating
- earth is over 3.8 billion years old
- moon is 4.5 billion years old
- sun 4.6 billion years old
42Organic evolution observations
- fossil record
- younger rocks have more organisms similar to
those living today (at levels from species to
kingdom) - fossils record includes appearances and
extinctions of many species - geographic distribution of organisms
- anatomy
- genetics
43Organic evolution conclusions
- the characteristics of populations of living
organisms have changed through time - life has become more complex
- life has become more diverse
- all life is related
- this is excepted as a factual observation
44Natural selection observations
- populations of organisms display a variety of
characteristics - random mutations provide variety
- domesticated plants and animals can be bred to
favor certain characteristics
45Natural selection observations
- the natural environment
- organisms with favorable characteristics for
their niche are more likely to thrive and
reproduce - organisms with unfavorable characteristics are
less likely to thrive and reproduce - a new niche or stress on an existing niche will
enhance selection
46Natural selection conclusion
- the natural environment provides conditions that
result in evolution through the process of
natural selection
47Natural selection speciation
- a population has a gene pool
- members of the population interbreed
- the population may become isolated from others of
a species - development of niches resource partitioning
- migration
- development of physical barriers
- populations may be selected
- by stress
- by opportunity
- isolation may result in genetic divergence
