Fossil Record
Which rock layer contains the newest fossils?
Images of the embryo and adult stages of three different organisms are shown.
Which of the following is the best conclusion that can be drawn from this evidence?
Having similar embryos indicates that these organisms eat the same types of food.
Having similar embryos indicates that these organisms live in a similar environment.
Having similar embryos indicates that these organisms share a recent common ancestor.
Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
Occurs when a catastrophic event changes the environment suddenly.
Gradual extinction
Mass extinction
A number of different species arise from one common ancestor.
Adaptive Radiation (aka, Divergent Evolution)
Gradualism
Coevolution
Speciation
Speciation is the outcome of:
Population growth
Reproductive isolation
Extinction
Sexual reproduction
Leopard frogs and wood frogs reach sexual maturity at different times in the spring and hence cannot interbreed. This is an example of:
Behavioural isolation
Geographic isolation
Gene pool isolation
Temporal isolation
Males of different species of the fruit fly Bactrocera that live in the same parts of the Fijian Islands have different elaborate courtship rituals. These rituals involve fighting other males. What does this represent?
Habitat isolation
Temporal isolation
Behavioral isolation
Gametic isolation
the total genetic information available in a population
population genetics
microevolution
gene pool
allele frequency
determined by dividing the number of a certain allele by the total number of alleles of all types in the population
population genetics
microevolution
gene pool
allele frequency
The emergence of new rivers or streams is a type of ____________ isolation.
Temporal
Mechanical
Behavioral
Geographic
Fossil records show that black bears increased in size during the Ice Age and decreased in size with warmer temperatures. What type of selection do these changes in size represent?
Allopatric
Directional
Disruptive
Stabilizing
Babies birth weight is an example of
Disruptive selection
Adaptive radiation
Stabilizing selection
Directional selection
Allele frequencies in a gene pool do not change, this is
random change

genetic equilibrium
punctuated equilibrium
When a species environment favors one dominant type of characteristic to the point that the other variations of the trait start to disappear is called _____.
disruptive selection
directional selection
