Evidence for Evolution

Question 1

Dealing with the geographical distribution of animals and plants

Answer 1

biogeography

Question 2

Made up of all the fossils ever discovered on earth

Answer 2

Fossil record

Question 3

Bones, teeth, imprints in rock, preserved in tar/amber

Answer 3

Types of fossil

Question 4

Requires a precise combination of conditions; very rare

Answer 4

Fossil formation

Question 5

Fossil found that is the link between reptiles and birds (mix of traits); shows that birds evolved from a reptile ancestor

Answer 5

Archeopteryx lithographica

Question 6

Technique used to compare the DNA in different species to determine how closely related they are; the more strands match, the more recent the shared ancestor

Answer 6

DNA hybridisation

Question 7

Sequence of amino acids making up particular proteins are compared across different species to establish a timeline for evolution (more differences = more distant common ancestry)

Answer 7

Comparative proteins

Question 8

Anatomy compared across different species to establish a timeline for evolution; looking for homologous structures

Answer 8

Comparative anatomy

Question 9

Structures in different species that are similar because of recent common ancestry

Answer 9

Homologous structures

Question 10

Structures in different species that are similar because of shared environmental selection pressures

Answer 10

Analogous structures
