This is the piece of evidence that looks at where species and populations are distributed on earth
What is biogeography
100
This agent is the only source of new alleles
What is mutation
100
This agent of evolution is when certain organisms are better adapted to their environment, and therefore have a greater chance of surviving and reproducing.
What is natural selection
100
This is how many extinctions there have been in the past
What is 5
200
This is one reason why the fossil record is incomplete
What is not all organisms fossilize, some areas have eroded, can't reach all the fossils
200
This agent is where new individuals enter or leave a population, thus changing the genetic composition of the population
What is migration/gene flow
200
This agent of evolution occurs when an event, such as a natural disaster, reduces the population in a random way.
What is genetic drift
200
What type of speciation occurs when there is a geographic barrier
What is allopatric
200
This is the proper name for a species
What is Acionyx jubatus (italicized)
300
An owl wing and a butterfly wing are considered to be this type of structure in relation to each other?
What is analogous
300
Female birds are attracted to the most colorful male birds. The bright plumage of male birds is not necessarily advantageous to their survival though. What type of agent is this?
What is sexual selection
300
A population of rabbits has been hit by a tornado. Remarkably, out of 5,000 rabbits, 100 of them were picked up by the tornado and dropped in a new uninhabited area. The rabbits moved to the new area have different allelic frequencies compared to the original population. This type of genetic drift has occurred.
What is founder effect
300
Two birds have different songs and do not recognize each other as potential mates as a consequence. What type of reproductive isolation is this?
What is prezygotic
300
This is the correct order of classification taxa from biggest/broadest to smallest/most narrow
What is domain, kingdom, phylum, class, order, family, genus, species
400
Structures that have become reduced in form and function are known as this
What is vestigial
400
A population of narwhals have 3 phenotypes for body color- black, grey, and white. Over time, the darker colors have been selected for, and the white color has all but disappeared. What type of natural selection/evolution has happened?
What is directional
400
A population of black bears have been hit by a hurricane. Out of 500 black bears, only 10 have survived. This type of genetic drift has occurred.
What is bottleneck effect
400
This type of speciation occurs when the population is in the same place (no geographic isolation), but somehow the population still becomes two different species
What is sympatric speciation
400
This type of speciation occurs when there are bursts of speciation, followed by long periods of no change
What is punctuated equilibrium
500
These are 4 pieces of evidence for evolution
What is biogeography, fossil record, comparative anatomy, biochemistry, and direct observations of natural selection
500
In a population of black rhinos, horn length has three phenotypes. The two extremes have become more prominent over time, while the intermediate has declined in the population. What type of natural selection/evolution has occurred?
What is disruptive
500
These are the 5 agents of evolution
What is genetic drift, mutation, sexual selection, natural selection, and gene flow/migration
500
This type of evolution is when two species mirror each other in evolution, that is, a change in one species will invoke a change in the other.
What is coevolution
500
This is the 4 steps to early earth life
What is 1. monomers (amino acids) formed 2. polymers formed 3. Protocells 4. RNA
