Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

History of Life Quiz

front 1

On a phylogenetic tree, the longer the branch, the longer the length of time that occurred before the next split in groups.

  • True
  • False

back 1

False

front 2

Scientists create clades by using:

  • monophyletic groupings
  • homologous traits
  • analogous traits
  • vestigial traits

back 2

homologous traits

front 3

Which is true about unrooted taxonomic trees?

  • They diverge from a single point and branch off
  • They show a common ancestor
  • They show a single lineage that connects organisms
  • They show a relationship between species

back 3

They show a relationship between species

front 4

Which phylogenetic models incorporates the possibilities of horizontal gene transfer?

  • Linnaean taxonomy
  • Web of Life

back 4

  • Web of Life
  • Ring of Life

front 5

A branch with more than two lineages is called a

  • branch point
  • polytomy
  • sister taxa
  • basal taxon

back 5

  • Mitochondria-first hypothesis

back 6

Mitochondria and Nucleus-first hypothesis

front 7

Maximum parsimony is used to

  • decipher mutations in DNA codes

back 7

determine most likely phylogenies

front 8

Transposons are most closed associated with

  • jumping genes
  • viral infections
  • transformation

back 8

jumping genes

front 9

Phylogenetic relationships do not show how organisms are similar or different, but do provide information on shared ancestry.

  • True
  • False

back 9

True

front 10

Some species are more "evolved" than other species since they have longer evolutionary histories than others.

  • True
  • False

back 10

False

front 11
