There are many sources of evidence to support the ______________ of evolution
hypothesis
theory
law
inference
Evolution can be defined as
a population that remains unchanged over time
the study of living things and their interactions with the environment
the hierarchy of life
a change in a population over time
The scientist credited with developing the theory of evolution is
Gregor Mendel
Rosalind Franklin
Charles Darwin
Albert Einstein
The mechanism of evolution which is sometimes referred to as "survival of the fittest" is also known as
natural selection
mutation
migration
genetic drift
One of Darwin's observations, during his travels around the world, was that individuals within a population
are identical to one another
are varied in their traits
do not share a common ancestor
Mutations occur due to
selective pressures on a population
overpopulation of a species within a gepgraphic area
cloning of organisms within a population
random changes of an individual's DNA
_________ causes changes in a population due to random chance.
Genetic drift
Migration
Natural selection
Survival of the fittest
When indivdual organisms move into or out of a population, it is called
Genetic drift
Migration
Natural selection
Survival of the fittest
When a population is separated by a physical barrier (river, canyon, mountain range, etc), it may evolve into 2 separate species. This is referred to as
sympatric speciation
allopatric speciation
population speciation
Darwin speciation
An organism is considered to be evolutionarily "fit" if it can
survive and reproduce
benchpress two times its weigh
run a 4 minute mile
find food & shelter
Which of the following are body parts that share a common function, but are NOT inherited from a common ancestor?
derived trait
analogous structure
homologous structure
vestigal structure
A vestigal structure in a human is the appendix. Specifically, this means that the structure is a reduced form (unused). Such a structure is considered to be
analogous
homologous
derived
vestigal
Humans and rhesus monkeys have in only 1 difference out of the 140 amino acids in their cytochrome C proteins. Humans and yeast have 42 differences out of the 140 amino acids in their cytochrome C proteins.
What can be inferred from this information?
Rhesus monkeys and yeast are very closely related, evolutionarily
Humans are more closely related to yeast than to rhesus monkeys
Humans are more closely related to rhesus monkeys than to yeast.
No conclusions can be made from these obseverations.
Which of the following is the study of past and present distribution of organisms?
comparitive embryology
biogeography
fitness
comparitive biochemistry
Based on the fossil evidence (shown in the figure), which organisms is evolutionarily the "youngest"?
monkey
lizard
fish
No information can be determined from the fossil evidence
