To assess ENVOLUTIONARY RELATIONSHIPS; looking at the similarities and
differences between organisms.
It helps IRRADICATE CONFUSION of naming species and sub groups; they are put into
Latin to avoid confusion.
Taxonomy? Assigning a species into a particular defined group or taxa.
The 5 kingdoms:
1. Animalia = Eukaryotic, tissue differentiation, multicellular, Holozoic Heterotroph. E.g.
2. Plantae = Eukaryotic, tissue differentiation, multicellular, Autotrophic Cellulose cell
wall. E.g. Flowers
3. Fungi = Eukaryotic, multicellular, unicellular, Saprophytic Heterotroph. E.g. Mould
4. Prokaryotae = unicellular, peptidoglycan cell wall. E.g. Bacteria
5. Protoctista = Eukaryotic E.g. Amoeba

Here's a taster:
A) Common Name: this varies from place to place
B) Scientific Name: Binomial name consistent from place to place.
Phylogeny = the science of establishing evolutionary relationships through classification.
These relationships can be shown on a phylogenetic tree.
DNA Hybridisation: comparing similarities in DNA base sequences between different species.
Step 1: Mix DNA sample 1 with species being tested.
Step 2: Heat to separate strands (breaking the hydrogen bonds).
Step 3: Allow different strands to hybridise through formation of complementary base pairs.…read more
