Evidence of Evolution

Question 0

Paleontology

Answer 0

Study of ancient items like fossils, bones, etc.

Question 1

4 main bodies of evidence

Answer 1

Paleontology
Embryology
Comparative anatomy
Molecular biology

Question 2

Fossil

Answer 2

Preserved bone or other trace of an ancient organism. Formed when the dead animal or something of an animal is left behind and buried by sediment.

Question 3

The _______ fossils are the _______ they are

Answer 3

Deeper ; older

Question 4

Morphology

Answer 4

Describing what fossils look like. Can be used with location of fossils to determine information about an organism’s ancestors.

Question 5

Transitional fossil

Answer 5

Not one generation of first species but gradual progression (all fossils)

Question 6

Biogeography

Answer 6

Where organisms live

Question 7

Embryology

Answer 7

Study if developmental patterns in embryos

Question 8

Vertebrates in _____ stages of ________ are similar

Answer 8

Early ; development

Question 9

Comparative anatomy

Answer 9

Comparing how organisms are put together through homologous structures and analogous structures

Question 10

Homologous structures

Answer 10

Structures that are derived from a common ancestor but not the same function and caused by divergent evolution

Question 11

Divergent evolution

Answer 11

Evolution toward different traits in closely related species

Question 12

Analogous structures

Answer 12

Structures that look similar but evolved from different structures and caused by convergent evolution

Question 13

Convergent evolution

Answer 13

Similar traits in very distantly related species

Question 14

Vestigial structures

Answer 14

Remnants of an organism’s evolutionary past and has no function

Question 15

Molecular biology

Answer 15

similarities in common biological molecules like DNA or proteins

Question 16

The greater the _________, the higher the ______ difference I. The compared molecules

Answer 16

Divergence ; %

Question 17

2 specific areas of molecular biology

Answer 17

Pseudo genes

Hox genes

Question 18

Pseudo genes

Answer 18

Non-functioning sections of DNA (don’t code for anything), carried along with functional DNA

Question 19

Hox genes

Answer 19

Come from distant common ancestor, determine head to tail development in embryos

Question 20

Genes shared by all organisms

Answer 20

“Master genes”
