Three Critical Thinking Questions
How do you know it is true?
Has it ever been observed?
Are you making any assumptions?
One More Question - Fossils
How much of the fossil was
actually found and how much
was added (assumed)?
“For instance, modern whales are
the descendants of four-legged land
animals…”
Biology:
Visualizing Life,
Holt, Rinehart,
Winston, 1998,
p. 177.

Critical Thinking
4 Components
Analysis
Inference
Interpretation
Deductive reasoning
Analysis • Determine the credibility of
the evidence.
• Are there any assumptions?
• Are there any logical
fallacies?
Ad Hominem – Name calling
Equivocation - Different meanings
Bifurcation – Either or fallacy
Strawman – Distorting the position
Analysis
Inference • What elements are needed
to draw the conclusion?
• We need to query the
evidence: ask questions
Analysis
Inference
Interpretation • Decode the argument
• Clarify the argument
• What is the real issue?
(presuppositional)
Analysis
Inference
Interpretation
Deductive • What does the premise
Reasoning really allow us to conclude?
• Draw a logical conclusion
based on the evidence
presented in the argument.

Will millions of years of mutations and
natural selection allow for amoeba to

Analyzing Popular Definitions of
Evolution
Evolution is change over time.
(valid / not valid)
Genetic change in a species over time
(valid / not valid)
Any change in the relative frequencies
of alleles in the gene pool of a
population (valid / not valid)
Challenging Question
What is a good definition of
Darwinian evolution?
Random mutation
1. _________________
Beneficial
2. _________________
Add new information
3. _________________
Must survive
4. _________________
Reproduce more offspring

Natural Selection
What is it?
What Is Natural Selection?
Charles Darwin
“It may be said that natural selection is
daily and hourly scrutinising, throughout
the world, every variation, even the
slightest; rejecting that which is bad,
preserving and adding up all that is good;
silently and insensibly working, whenever
and wherever opportunity offers.”
Charles Darwin, On the Origin of Species by Means of Natural Selection, or
the Preservation of Favoured Races in the Struggle for Life, 1859, p. 84.
Three Assumptions about
Natural Selection
1. Assume natural selection is
responsible for appearance of design
and complexity.
2. Assume an external source as the
source of design.
3. Assume natural selection has the
capability to choose beneficial
mutations (intelligence).

3 Questions About Natural Selection
1. What is it that natural selection actually
does and how does it work?
2. Selection implies intelligence. Who or
what is actually doing or causing the
selection?
3. Since selection does not address the
origin of information, and mutations
are known to cause a loss of
information or function, is there any
observational evidence for where the
vast amount of information in DNA
came from?
What Is Natural Selection?
It is an artificial mechanism
devised by man to replace the
power and intelligence of God.

“Imagine that infinitesimal fluctuations in
density were present in the early universe….
The expansion of the universe must have
exerted a stabilizing influence on such
irregularities. The expanding universe has the
effect of greatly impeding what otherwise
might have been catastrophic forces….
Nevertheless, the process of growth of
fluctuations went on for a very long time,…”
Prentice Hall, Science Explorer: Life
Science, 2002, p. 46.
“The first cells could not have needed
oxygen to survive. They probably were
heterotrophs that used the chemicals
in their surroundings for energy….. At
some point, some of the cells may
have developed the ability to make
their own food.”

ago in a pool of chemicals.
