LECTURE 8 FLASHCARDS

Question 1

What trees would be considered “parsimonious”?

Answer 1

Trees that have fewer evolutionary changes (2 changes vs. 3 changes) - two change would be most likely

Question 2

What is the biological species concept?

Answer 2

Groups of actually or potentially interbreeding natural populations that are reproductively isolated from such groups

Question 3

What is the morphological species concept?

Answer 3

Defines species based on physical characteristics

Question 4

What is the Ecological Species concept?

Answer 4

Defines species based on ecological roles and interactions

Question 5

What is the Phylogenetic species concept?

Answer 5

Defines species based on evolutionary relationships and genetic data

Question 6

What is the genotypic cluster concept?

Answer 6

Uses genetic data to identify cluster of individuals

Question 7

What do species form via?

Answer 7

Speciation

Question 8

What is speciation?

Answer 8

The process by which a single species splits into two or more distinct species over time.

Question 9

What does speciation require?

Answer 9

Reproductive isolation (barrier to gene flow)

Question 10

What is allopatric speciation?

Answer 10

Species split due to a geographic barrier or because some individual; moved to a different location

Question 11

What is Sympatric Speciation?

Answer 11

Species is split by reproductive separation even though they are in the same place.
