What is the taxonomic hierarchy?
|
Kingdom, phylum, class, order, family, genus, species
|
A group of potentially interbreeding natural populations that are capable of producing viable, fertile offspring is ____.
|
A species
|
________ is the evolution of a new species. It is a population level process that begins with the isolation of a small number of individuals from the larger population of a species.
|
Speciation
|
______ is a method used to reconstruct relationships among species based on nested sets of shared derived characteristics.
|
Cladistics
|
What are the 2 main assumptions when determining how to create a cladogram?
|
1-speciation is a branching (splitting) process2-the best explanations for evolutionary change are the most parsimonious.
|
What is the 1st step in making a cladogram?
|
Find a group you are interested in
|
What is the 2nd step in making a cladogram?
|
Select characters that vary among species and go to an out-group to compare.
|
What is the 3rd step in making a cladogram?
|
Collect information on characters for all taxa.
|
What is the 4th step in making a cladogram?
|
Search for the most parsimonious cladogram.
|
What is a plesiomorphy?
|
A primitive character
|
What is a symplesiomorphy?
|
A shared primitive character.
|
What is an apomorphy?
|
A derived character.
|
_________ is a shared derived character.
|
Synapomorphy
|
______ is a derived character in a single species.
|
Autapomorphy
|
If a characteristic evolved from a common ancestor, it evolved this way...
|
