Chapter 22 (Pomarico) BIOL 1202 Final
Exam And 100% Correct Answers
2025-2026 Updated.
Who created the first "convincing" case of evolution? - Answer Charles Darwin
the transformation of the lifeforms on earth over time - Answer evolution
Darwin's specific "term" that summarized the concept of evolution, generational change over
time - Answer descent with modification
Is evolution linear? (Hint: think of it in terms of humans and chimpanzees) - Answer No;
when many people think of evolution, they think of it in terms of progressing towards humans,
but this is incorrect. "Humans did not evolve from chimpanzees; they share a common
ancestor."
When looking at a tree of organisms with many branches, where is the common ancestor? -
Answer Point farthest back where all the branches meet
How does the definition of evolution relate to genes and allele frequency? - Answer
Evolution is the change in gene and allele frequency within a population over generational time
What kind of change adds a new allele into a population or causes one allele to be favored over
another (creation of new genes)? - Answer mutation
If a mutation occurs within a population, how might that mutation affect the existing alleles? -
Answer It may add a new allele that is favored in the population or create a change in the
organism that favors one allele over another
If one allele in a population is favored greatly over another, what will happen to the disfavored
allele? - Answer Not going to be passed on as frequently to the next generation because the
organisms with that allele struggle to survive or reproduce
When thinking about evolution as "change over time," what is the unit of time used to quantify
evolution? - Answer generational time (time between generations)
, T/F: Generational time between all organisms is the same. - Answer False; the length of a
generation for different organisms varies in time (so some groups might "evolve" more quickly
than others)
Why wouldn't 40 years be enough time to observe evolutionary change in humans? - Answer
Not enough generations have passed to yield evolutionary change (probably only 1 or 2)
About how much time is needed to see evolutionary change within bacteria? - Answer a day
or two could be plenty
About how much time is needed to see evolutionary change within humans? - Answer
possibly 200-300 years
Why is the idea that evolution is "controversial" (for lack of a better word) dumb? - Answer
there is IRREFUTABLE evidence that evolution has occurred
How did Western Philosophy view Darwin's ideas of evolution and descent with modification? -
Answer Western philosophy disapproved of Darwin's theory of evolution because different
ideas about the creation of life and species were already heavily ingrained (ex: The story of
Creation in the Bible)
What was the principle most popular hypothesis for the origin of species within Western
Philosophy? - Answer creationism
hypothesis for the origin of species that states all species were created exactly as they exist
today (and have not changed over time) - Answer creationism
Why does creationism clash with Darwin's theory of evolution? - Answer Within creationism,
there is no "descent with modification" or change over time, which is a key feature of Darwin's
ideas
Why was creationism so heavily ingrained in Western philosophy? - Answer The idea of
creationism fit well with religion that was practiced in European cultures at that time (ex:
Catholicism). Religious orders were very often involved in the education processes. The
Churches also had large influences over country leadership. (The Church ruled all)
What is creationism in the biblical sense? - Answer the philosophy that all organisms were
created at exactly the same time ("At the beginning there was nothing, and then there was
light.")
