Question 1

Node

Answer 1

Split in phylogeny tree

Question 2

Cladogenesis

Answer 2

Evolution from one specie to two or more

Question 3

Cladistics

Answer 3

Classification of species based on evolutionary relationships
Compares homologous characteristics in a cladogram

Question 4

Cladogram

Answer 4

Shared primitive characters

Shared derived characteristics

Question 5

Parsimony

Answer 5

Requires the fewest # of changes

Question 6

Molecular clocks

Answer 6

Use genetic sequences to measure evolutionary time

Question 7

Neutral Theory

Answer 7

Neutral mutants have no effect on fitness

Predicts rate of molecular change in “clock life”

Question 8

Issues with molecular clock

Answer 8

Different proteins have different clock rates

Need a fossil record to calibrate clock

Horizontal gene transfer

Answer 9

Obtaining genetic material from another organism without being an offspring
Bacteria - conjugation, transformation, transduction
