Bio Ch 6 Flashcards
What are the three similarities between the Big Bang Theory and the Genesis account of Creation?
They both have a beginning
Light was created first
The universe is stretching/expanding
What are the 3 modes of natural selection?
Stabilizing selection
Direction selection
Disruptive selection
What are the 5 patterns of evolution?
Speciation
Gradualism
Punctuated equilibrium
Divergent evolution
Convergent evolution
What is science
Study of the natural world
What is evolution?
Explanation of natural world
Verifiable theory that can be accepted with clear evidence
Work in progress with certain “gaps” in fossil record
What is evolution not?
Atheistic perspective
Explanation that denies the supernatural
Explanation of how everything came into existence
Perfect explanation of how every living species came to be as they are today
What did Charles Darwin study on the Galapagos? What theory did he develop?
Finches. Natural selection
How is microevolution different from macroevolution?
Micro- small scale
Macro- large scale
What are the two theories for how the universe began? Which has more evidence?
There is no beginning
There is a beginning (more evidence)
What can be used to determine the age of the universe?

What IS important for Christians to agree with
God created all things, was there at the beginning
What is NOT important for Christians to agree with
How God created everything
How long it took God to create the universe
God created humans instantly or through long process
What is natural selection? Be able to identify advantages in a population
A natural process that selects certain traits in organisms based on genetic trait that are favorable for survival.
Genetic variation exists
There are limited resources
Some traits allow organisms to get those resources better than others
The organisms that get the resources live on; those that don’t, diminish in the population
The appearance of the favorable trait is now more common
What are the three modes of natural selection
Stabilizing- Favorable trait is the medium range of the phenotypes
Directional- Favorable trait is one extreme range of the phenotype
Disruptive- Favorable trait is both extreme of the phenotype
What are the five patterns of evolution
Speciation- New species emerge from “old” species
Gradualism- Small modifications over long periods of time
Punctuated equilibrium- Rapid changes followed by no change over long periods of time
Divergent evolution- Multiple species from 1 common ancestor
Convergent evolution- Species that are unrelated have similar traits due to similar environment
