Taxonomy
branch of biology that deals with the naming and classification of living things
Early Schemes
Aristotle= habitat
John Ray= Structure
Carolus Linnaeos
father of modern taxonomy
Used structural similarities and evolutionary relationships
Evolution
all present forms of life share a common ancestor and evolve from simplire more primitive ancestors/ organisms
Classification categories
Kingdom
Phylum
Class
Order
Family
Genes
Species
Nomenclature
a system for naming organisms
BEFORE LINNEAUS- organisms name =
genus by 7-9 latin words
LINNEAUS's NOMENCLATURE
2 word naming system [binomial nomenclature] is the scientific name - GENUS & SPECIES
THEORY OF EVOLUTION
CHARLES DARWIN
relationships exist between species
Species
natural group or population of organisms that interbreed in nature
Taxonomic key / dichotomous key/ classification key
identify organisms through series of questions
objective powers
low-10x X 10x = 100x
middle-10x X 25x = 250x
high- 10x X 40x = 400x
********* 1 mm =
1,000 um
to measure field diamater under high power ...
if low power = 100 x
if high power = 400x

ratio between them is 100/400 = 1/4 X field diameter AKA known over unknown
