Species

Phylogeny
the history of the evolution of a species or group
Taxonomy
classification of living organism
Binomial Nomenclature
system of naming organisms
Classification
grouping living organisms
Taxon
a single group
Common Ancestor
An ancestor shared by two or more descendant species.
Phylogenetic Tree
a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
Homologous Structure
similar physical features in organisms that share a common ancestor, but the features serve completely different functions.
Prokaryotic Cell
no membrane bound organelles
Eukaryotic Cell
membrane bound organelles
Dichotomous Key
ask yes or no questions to classify a newly discovered organism compared to existing organisms
Autotroph
produces its own food
can either be photosynthetic or chemosynthetic
Heterotroph
eats other organisms to get energy
natural selection
the process through which populations of living organisms adapt and change.
Artificial Selection
the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations
