Science
Western Religion
Premise 1 - God created
humanity.
Premise 1 - All life forms
on earth go through the
process of evolution.
Premise 2 - Humanity did not
evolve.
Conclusion 3 - Therefore,
there will be no evidence
of human evolution.
Premise 2 - Humanity is a
life form on earth.
Conclusion 3 - Therefore,
there will be evidence of
human evolution.

Do the same laws of
evolution apply to
human beings?

In a new book, documentary, and promotional Web site, paleontologist Jorn Hurum, who led the
team that analyzed the 47-million-year-old fossil seen above, suggests Ida is a critical missinglink species in primate evolution. The fossil, he says, bridges the evolutionary split between
higher primates such as monkeys, apes, and humans and their more distant relatives such as
lemurs. "This is the first link to all humans," Hurum, of the Natural History Museum in Oslo,
Norway, said in a statement. Ida represents "the closest thing we can get to a direct ancestor."

Science Limits Itself to:
 The physical evidence
 Possible theories that explain the
patterns of physical evidence
 New improved theories as more
physical evidence is found
 No theories that cannot be supported
by physical evidence

Five Principles of Evolution
 Variation has a genetic origin due to
mutation and recombination
 Natural selection and gene flow causes
changes in gene frequency in populations
 Adaptation is genetically based and leads
to changes in population over time
 Species formation evolves through
reproductive isolation
 Genetic changes through natural selection
lead to new species

For Example…

strains of flu
becoming so
hard to fight off
each year?

And in the future…
Children downstream of polluted rivers lose 5 points in IQ
scores when they reach adulthood. How will this affect
the gene pool of humanity in ten generations?

Conclusions From Science
 Humanity has evolved from earlier life
forms.
 Those life forms have been identified by
fossil records.
 Humanity as we know it began its
evolutionary path about 170,000 years
ago in Africa.

However…
An Argument from Theology
or Philosophy Could Be…
Premise 1 – God is the essence of complete
consciousness.
Premise 2 - The process of evolution points
to the design and creation of increasingly
higher levels of consciousness over time.
Conclusion 3 - Therefore, God is the
Intelligent Design guiding evolution
towards complete consciousness.
