Cell Theory Correct answer-All organisms are made of cells, and all cells come from pre-
existing cells.
Conclusion: If you trace a cell's lineage back far enough, you will discover that all cells are
descended from a common ancestral cell
Evolution Correct answer-The heritable change in a population over time or a change in
gene frequency in a population over a number of
generations
Proximate process Correct answer-what happens in short term, measured in fractions of
lifetimes
Ultimate process Correct answer-longer timeframe (lifetime or more)
Evolutionary Theory Correct answer-2 General Ideas:
Evolution explains variation
All species are related to each other through common ancestry
Biomes Correct answer-collection of similar ecosystems but not part of hierarchy because
it doesn't have emergent properties

Before the mid-1800s we knew: Correct answer-a. Organisms have offspring similar to
themselves.
b. We could select individual plants and animals on our farms to breed and produce offspring
that we considered beneficial.
c. There exists a large amount of diversity/variation among organisms within a species.
d. Differences among the members of a population mean that not all are affected in the same
way by ecological factors
e. The variation between species may mean that not all areas that can do so will support a
population of a particular species or actually have a population present.
f. Typically, individuals produce more offspring than what the environment can support.
Also, Special Creation, species have never changed and are unchangeable, variation between
individuals is unimportant, and Aristotle's Great Chain of Being.
Emergent Properties Correct answer-The collection of the units at one level takes on a
trait that is greater than the sum of the parts
Ex: Social groups have the emergent property to have safety in numbers
Evolution is an emergent property of populations
Organisms Correct answer-Individuals that are typically a collection of organ systems.
They are acted on by natural selection.

Jean Baptiste de Lamarck Correct answer-first evolutionist to believe that organisms
change over time. The theory of acquired characteristics: individuals change as a result of
environmental pressures and then pass those traits to offspring
ex: you're JACKED and then your child is born JACKED
Fitness Correct answer-number of viable offspring you produce in your lifetime
Adaptations Correct answer-A heritable trait that increases the relative fitness of
individuals having that trait
A process by which individuals within a population acquire traits that increase their relative
fitness
Australian Rabbits Correct answer-Rabbit invasion, tried to control population with
myxomatosis virus that only kills rabbits, it was pretty effective in killing rabbit pop , but only
killed 99.9% so the rabbit population that was resistant survived and passed on resistance to
offspring through placenta
What do rabbit and virus population have in common?
They both have variation (virus- virility, rabbit- variation in susceptibility)
Both are populations
Both have differential reproduction
Homologies Correct answer-traits in common due to inheritance from a common
ancestor

Macroevolution Correct answer-the change of one major taxonomic group into another
(ex: fish to amphibians to reptiles) or creation or extinction of a species
1.) Homology
2.)Fossil Record
3.) Vestigial Traits
Microevolution Correct answer-the change in a population over generations that helps to
separate populations from each other genetically.
Accumulation of microevolution over time leads to macroevolution
Evolutionary Trends Correct answer-resulted from macroevolutionary processes
a. An increase in multicellularity
b. An increase in complexity
c. An increase in ways to capture energy for use
d. An increase in ways to deal with the environment - biotic and abiotic
e. An increase in diversity (snowball effect)
Construct a hypothetical scenario that explains the evolution of feathers in birds (feathers are
modified scales) Correct answer-Scales that vary in shape/waviness may have an
advantage regulating body temp. allowing them to have more energy to get food
