EVOLUTION & CLASSIFICATION
CLASSIFICATION Grouping organisms based on similarities.
This is the science of TAXONOMY
Classification is based on common ancestors with: Similar structures/anatomy Similar biochemical makeup Similar embryonic development
TAXONOMY KINGDOM (least similar) PHYLUM CLASS ORDER FAMILY GENUS SPECIES* (most similar)
*NOTE: members of the same SPECIES can mate and produce fertile offspring.
BINOMIAL NOMENCLATURE We use a 2 part naming system to identify
an organism, using their GENUS and SPECIES. Ex. Humans are Homo sapien
THE KINGDOMS Monera
Single-celled organisms Heterotrophs No nucleus (prokaryotic)
Ex. Bacteria
THE KINGDOMS Protista (Protists)
Two different groups Heterotrophs (protozoa) Autotrophs (alga)
Single-celled organisms Have a nucleus (eukaryotic)
Ex. Amoeba (heterotroph) Algae (autotroph)
THE KINGDOMS Fungi
Multi-cellular Heterotrophs (non-photosynthetic)
Ex. Mushrooms & Yeast There are 14,000 different
species of mushroom
THE KINGDOMS Plant
Multi-cellular Autotrophs
Ex. Tree & Bush
THE KINGDOMS Animal
Multi-cellular Heterotrophs
Ex. Birds
THE ANIMAL KINGDOM Divided into different phyla.
Coelentrates Hollow body cavity with one opening
Ex. Jellyfish & Hydra Annelids
Segmented bodies & tube within a tube body cavity Ex. Earthworm
Arthropods Segmented bodies, jointed legs, exoskeleton
Ex. Grasshopper & Lobster Chordates
Have a backbone with dorsal nerve Ex. Fish, Amphibians, Reptiles, Birds, Mammals
