People
This person studied geographical changes
Hutton
This type of hybrid zone demonstrates how reproductive barriers are weakened until the two species become unified
Fusion
A heritable trait that helps the survival and reproduction of an organism in its present enviornment
Adaptation
This type of barrier arises when the gametes prevent fertilization from taking place
Gametic barrier
Why are more offspring produced than are able to survive
resource competition
This individual claimed that species stay the same regardless of time
Plato
Two species who can mate produce a viable hybrid offspring. Over time these hybrids continue to be born, however, the two species remain different species. What type of hybrid zone is this an example of
Stability
What is it called when two species evolve in diverse directions from a common point
Divergent evolution
These types of behaviors occur prior to zygote formation
prezygotic barriers
Autopolyploidy results when mitosis is not followed by what?
Cytokinesis
These two individuals studied how the Bill shape of a Finch was related to its habitat
Peter and Rosemary Grant
A chromosomal error during cell division could result in what type of speciation
Sympatric speciation
These types of structures have no known function but could be used to argue descendance from a common ancestor. (wings in flightless birds)
Vestigial structures
Which type of isolation can be explained by the presence or absence of a specific behavior
behavioral isolation
What term describes when species diverge at a slow pace as traits incrementally diverge
gradual speciation
Which individual noted that changes are seen across different geographical regions?
Georges-Louis
Due to a recent avalanche, some members of a population got separated from other members of their species. Over thousands of years, the two groups that became separated have lost the ability to mate with one another. This is an example of....?
Allopatric speciation
The wings of insects and bats are a great example of...
Convergent evolution
A certain species of crab only lives/mates on land, while another species typically lives/mates exclusively in the water. This is an example of what type of barrier?
habitat isolation
Aneuploidy results due to _______ during meiosis causing the gametes to have too many or too few chromosomes
nondisjunction
These two famous people presented their scientific papers before the Linnean Society
Charles Darwin and Alfred Wallace
The honeycreeper birds are a perfect example of ___________ because they all evolved from a founder species, each with their own characteristics to match their diet
adaptive radiation
These types of structures indicate some sort of relation between species due to similar construction
Homologous Structures
A certain species is only active during the months of January-March and hibernates the rest of time. Another species is only active from May-December. Thus, these species never mate despite being located in the same habitat. What is this an example of?
Temporal Isolation
What term describes when species diverge quickly and then remain unchanged for long periods of time.
punctuated equilibrium
