Question 1

New techniques used to establish evolutionary relationships

Answer 1

Genome sequencing
Antibody-antigen interactions
amino acid sequencing

Question 2

How can genome sequencing help establish evolutionary relationships?

Answer 2

The more similar the base sequence are between organism, the more closely related the organism are.

Question 3

How can amino acid sequencing help establish evolutionary relationships?

Answer 3

The amino acids that make-up proteins in an organism can be sequenced and compared to organism. The more
similar the amino acid sequence the closely related.

Question 4

How can antibody-antigen interactions help establish evolutionary relationships?

Answer 4

Species produce specific antibodies that recognise foreign proteins.An organism’s antibodies can be isolated and mixed with another to see how antigen-antibody complexes are formed.

The more complexes that form the more closely related the organism are.
