Evolution Unit

Charles Darwin- species of life have
descended over time from common ancestry,
proposed the scientific theory of evolution
resulted from a process that he called
natural selection.

Homologous Structure- similar structure
different function

Analogous Structure- structures similar in
function but different structures

Vestigial Structure- Structures once used by
our ancestors but have shrunk for no use
today

Fossils- the preserved trace, imprint, or
remain of a plant or animal

Phylogenic Tree- A chart showing

evolutionary relationships
Embryology- the branch of biology that
studies the formation and early development
of living organism

Evolution- to evolve

Natural Selection- It is a key mechanism of
evolution.

Mutation- a change or alteration in form or
qualities

Adaption- a trait that helps an organism
survive and reproduce

Survival of the Fittest- Process by which
individuals that are better suited to their
environment survive and reproduce most
successfully; also called natural selection

Fitness- ability of an organism to survive
and reproduce in its environment

CLASSIFICATION UNIT:
What's the definition of taxonomy? Is the branch of
science concerned with classification of organisms

Binomial Nomenclature- the system to assign a
specific name- involves genus and species ex: The
brown grizzly bear

Eukaryotic cell- DNA contained inside a nucleus
(blow pop)/multi and unicellular/”condo” more
complex/many organelles/cell membrane/animalplant-protista-fungi

Prokaryote cell- DNA is not contained/bacteria
cell/has cytoplasm and ribosomes besides its DNA/
 Virus- an infective agent that typically consists of a
nucleic acid molecule (RNA) in a protein coat and is
able to multiply only within the living cells of a host

Autotroph-organisms capable of making their own
food

Heterotroph- organisms that consume food already
made for them

Order of classification- King, Phylum, Class, Order,
Family, Genus, Species

Taxonomy-the science of classifying organisms?

Six kingdoms- Archaebacteria, Eubacteria, Protists,
Fungi, Plants, Animals
