Molecular evidence
Chytochrome C
Protein used for respiration
We can compare the amino acid sequence for this protein in two species
Less diff = more closely related
Three domain system
•eukarya- organism with cells that contain a nucleus
Prokaryotae split to arches and Bactria
Due to molecular evidence :
RNA polymerase different different in bacteria and archae
Bonds in Lipids in cell membrane are different
Anatomical evidence
Similarities in structure and function of different body parts
Embryological evidence
Similarities in early stages of organisms development d
Behavioural evidence
Similarities in behaviour of organism
