Evolution Exam 1 – FAU – Study Guide & Revision Notes
TRUE or FALSE: human beings as we know them, developed from earlier species of animals -
ANS ✔✔True
What are 2 commonalities of all life - ANS ✔✔-all life possesses RNA/DNA
-all life evolved
Evolution= Descent with modification. What does this mean? - ANS ✔✔Change in the
properties of populations of organisms, or groups of such populations, over the course of
generations
Evolutionary biology has applications in what 6 things? - ANS ✔✔-health sciences
-agriculture
-natural products
-conservation and environment management
-understanding ourselves
-Entertainment
What are vestigial structures? - ANS ✔✔A useless rudimentary version of a body part that has
an important function in other, closely allied, species
,What did Darwin argue about vestigial structures? - ANS ✔✔Argues that vestigial traits are
difficult to explain under the theory of creation, but readily interpretable under the theory of
descent with modification
What are some examples of vestigial structures that were talked about in lecture? - ANS ✔✔-
human's tiny tailbone (coccyx)
-our arrector pilli muscles on our hair follicles (goosebumps)
What is Special Creation? - ANS ✔✔-species do not change
-lineage do not split
-each species is separately created
- each species in independently created
-earth and life are young
What is descent with modification? - ANS ✔✔-species change over time (microevolution)
-lineages split and diverge (speciation)
-new life forms derive from older life-forms (macroevolution)
-all life forms are related (common ancestry)
, -earth and life are old
What is microevolution? - ANS ✔✔Species are not immutable, but change through time
Ex. In a population of birds, the average beak sizes may change from one generation to the next
What are some examples of microevolution? - ANS ✔✔-Selective breeding/ artificial selection:
humans selectively breed wolves to create dogs and many different kinds of dogs
-direct observation
-vestigial structures: coccyx, goosebumps
What is speciation? - ANS ✔✔Lineages split and diverge, thereby increasing the number of
species
ex. An ancestral species of birds, for instance, may give rise to two distinct descendant species
What is a species? - ANS ✔✔Populations, or groups of populations, within and among which
individuals actually or potentially interbreed and outside of which the do not interbreed
What are some examples of speciation - ANS ✔✔-Natural populations
-lab experiments: a study by Dianne Dodd on the fruit fly on the mating preferences of fruit flies
from populations adapted to different diets. (Same wanted to mate with same 90% of the time)
