Q

Why is it important for Christians to relate God’s world and God’s Word – science and Scripture?

A

It builds faith and trust in Scripture (the Bible), and it helps believers use the wonders of science to introduce others to the wonders of new life in Christ revealed in God’s Word.

17
Q

Created kinds may be called ___________, a combination of the Hebrew words bara for ___________ and min for ___________.

A

baramins; create(d); kind

18
Q

Explain why no Christian familiar with the 4 Cs of biblical history would ever have accepted “fixity of species.”

A

The Bible refers to “kinds” in both the Creation and Flood accounts in Genesis. This does not mean “species” — it simply means kinds — which can show a lot of variety and diversity built into each one. For example, the cat kind can encompass everything from a house cat to a cheetah to an African lion. This view takes into account the major changes that occurred when mankind corrupted God’s creation; e.g., plants producing thorns, and animal predators beginning to kill and eat other animals. Fixity of species would not allow for the re-population of the earth by animals following the Great Flood — meaning that every animal that every lived in every kind would have had to be represented on the ark which was not feasible or necessary.

19
Q

What does “molecules to man” evolution need that neither microevolution nor natural selection provide?

A

“Molecules to man” evolution absolutely requires a HUGE INCREASE IN BOTH THE QUANTITY and QUALITY OF GENETIC INFORMATION, and neither mutations nor Darwinian “ selection” can provide either, since they only change or select existing varieties (pointing back to prior acts of creation).

20
Q

Use lions chasing zebras to explain the difference between natural selection and ecological competition.

A

Natural selection is NOT lion vs. zebra; it’s lion vs. lion (who can catch a zebra) and zebra vs. zebra (who can escape the lion). In other words, natural selection is NOT INTERspecific competition (between species); it’s INTRAspecific competition (within species). Even members of a plant species compete for water and minerals from the soil and a place in the sun.

21
Q

Use mosses, ferns, and shrubs to explain the differences between real simple-to-complex change, ecological succession, and imaginary evolutionary change by natural selection.

A

Evolution is a hypothetical process that is supposed to change a few simple forms over time into many complex and varied forms. There is a real process of change through time in which a few life forms are followed by a series of more and more complex and varied forms, but the real process is ecological succession. If you watched a certain area of bare rock over time, as scientists have, you could observe a series of changes from lichens to moss, ferns, shrubs, and trees. But the lichens didn’t evolve into the moss, nor the moss into the ferns, etc. Rather, each living community changed the environment in ways that paved the way for the next community to move in.

22
Q

Explain why creationists think that “natural selection” works best as “unsurvival of the unfittest.”

A

Peppered moth case: Natural selection did NOT produce a “new and improved moth”; the dark moth was already present. Pollution made the light form less camouflaged, and so (presumably) natural selection eliminated more light than dark moths. Had natural selection “gone to completion” and totally eliminated the light moth, the species might now be well on the road to extinction, since reduction in pollution has now made the dark moth less camouflaged.

23
Q

The “late, great” evolutionist S. J. Gould called imperfections in living things evidence of ___; creationists call them evidence of ___.

A

evolution; corruption (mutational defects following sin)

24
Q

Compare creationist and evolutionist explanations for variation in beaks among Galapagos (“Darwin’s”) finches.

A

Creationists and evolutionists would both say that, given finches with a variety of beak types, natural selection helps us to explain how and where the different varieties survived as they multiplied and filled the earth. A biblical creationist would also add that the “struggle and death” part of migration did not begin until man’s rebellion ruined the world God had created without death.
