Building Blocks in Life Science Chapters 1-5 Flashcards
Use mosses, ferns, and shrubs to explain the differences between real simple-to-complex change, ecological succession, and imaginary evolutionary change by natural selection.
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.
adaptions are design features that suit each organism for its special role in the web of life
creation
Random changes in genes that often change normal genes into alleles producing defects or disease (e.g. sickle cell hemoglobin)
mutations
black, brown, grizzly, polar, and panda bears
morphotype
Why is it important for Christians to relate God’s world and God’s Word – science and Scripture?
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.
Explain why creationists think that “natural selection” works best as “unsurvival of the unfittest.”
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.
several small groups separate from a large population, each with percentages of alleless different from those in the original gene pool (e.g. language groups moving away from the Tower of Babel)
genetic drift/founder effect
look-alike species of fruit files with different chromosome numbers
fertilotype
many defects and diseases result from chance changes in heredity called mutations
corruption
Created kinds may be called ___________, a combination of the Hebrew words bara for ___________ and min for ___________.
baramins; create(d); kind
Explain why no Christian familiar with the 4 Cs of biblical history would ever have accepted “fixity of species.”
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.
Members of a kind separating into distinctive subtypes as they “multiply and fill” earth’s environmental diversity (e.g. generalized bears leaving the Ark becoming black, brown, grizzly, and polar bears).
specialization
flood conditions are ideal for forming fossils
catastrophe
Only a few members of a species with a large gene pool survive a major disaster (e.g. animals aboard the ark)
genetic bottleneck
Barriers or preferences in the choice of a mate separate some parts of a gene pool from others (e.g. culture and language separates humans; size and temperament separate dogs)
reproductive isolation
