Phylogeny and gradualism

Question 1

Gradualism

Answer 1

The model of timing evolution
- when geologic and climate condtions are stable evolution may occur gradually

Question 2

Fast evoultion

Answer 2

When geologic and climate condtions are changing evolution may occur more quickly

Question 3

Punctuated equilibrium

Answer 3

Caused when long periods of no change can be interrupted by bursts of rapid change

Question 4

Phylogeny

Answer 4

The evolutionary history of a group of related organisms and is represented by a phylogenetic tree

Question 5

Clade

Answer 5

A group of organisms that include an ancestor and all of its descendants

Question 6

Cladistics

Answer 6

Method of comparing traits in related speice to determine ancestor- descendent relationships/ represented as cladograms

Question 7

Phylogenetic classification

Answer 7

Involves placing organisms in groups based on their evolutionary history

Question 8

Linnaeus

Answer 8

Classified organisms base don obvious physical traits/ grouped together organisms if they looked alike
