Evolutionary history or the evolutionary family tree of organisms

Question 2

Parsimony

Answer 2

“More than likely”
“If all things are equal, the simplest explanation for how that occurred is probably the most right”

Question 3

Cladogram

Answer 3

A phylogeny tree made of clades that are based on synapomorphies

Question 4

Phylogram

Answer 4

A scaled phylogeny

Question 5

Endogenous retroviruses

Answer 5

Past viruses
Inserted into genome they then are transcribed in the following genes

Question 6

Transposons

Answer 6

Segments of DNA capable of shifting from one location to another
(Carried by plasmid and leaves a copy of itself behind)

Question 7

LINEs/SINEs

Answer 7

INterspersed Elements
Inserted retroviruses are synapomorphies

Question 8

Pseudogenes

Answer 8

Genes that are expressed due to mutation, esp. in promoter region

Question 9

Atavistic trait

Answer 9

Originally gone but mutations bring it back temporarily

Question 10

Snapping shrimp

Answer 10
