5.4.3 - Evidence Of Evolution & The Scientific Community

Question 1

What Are Sources Of Evidence That Support The Theory Of Evolution?
(2 Points)

Answer 1

~ Genomics.

~ Proteomics.

Question 2

What Is Genomics?

Answer 2

Using DNA sequencing to determine the sequence of bases that make up a gene.

Question 3

Describe ‘Genomics’ As A Source Of Evidence For The Theory Of Evolution
(4 Points)

Answer 3

~ Base sequences of some genes are very similar across many species, indicating common ancestry.

~ The level of similarity between base sequences and genes, gives a measure of how long ago two species diverged.

~ Similar base sequences = diverged recently.

~ Different base sequences = diverged a long time ago.

Question 4

Describe ‘Proteomics’ As A Source Of Evidence For The Theory Of Evolution
(4 Points)

Answer 4

~ Sequencing proteins, to determine the order of amino acids in the primary structure.

~ Similar amino acid sequence = closely related, vice versa.

Question 5

What Are Sources Of Evidence That Support The Theory Of Evolution, Within Scientific Communities?
(3 Points)

Answer 5

~ Scientific journals.

~ Peer review.

~ Conferences.

Question 6

Describe ‘Scientific Journals’ As A Source Of Evidence For The Theory Of Evolution
(2 Points)

Answer 6

~ Used to share ideas and theories.

~ Other scientists can then repeat experiments, to test reliability.

Question 7

Describe ‘Peer Review’ As A Source Of Evidence For The Theory Of Evolution
(2 Points)

Answer 7

~ Scientists who work in that area, read and review.

~ Check for validity.

Question 8

Describe ‘Conferences’ As A Source Of Evidence For The Theory Of Evolution
(2 Points)

Answer 8

~ Encourages discussion.

~ Sharing of ideas.
