survival of the fittest or best adaptated survive to reproduce
Natural Selection
When a farmer picks the best crops or animals to breed in order to get offspring with the wanted characteristics
Artificial Selection
When one species evolves or changes into more than one species
Speciation
When a physical barrier separates two organisms and they eventually evolve into two species (one type of speciation)
Geographic Isolation
When two organisms are separated due to the time the organism mates, which eventually will result in the evolution of two species (one type of speciation)
Reproductive Isolation
Two types of speciation
Reproductive and Geographic Isolation
Compares the embryos of two organisms to see how genetically similar they are
Embryology
Compares the structure of organisms to compare the similiarities
Anatomy
Compares the chemical makeup of two organsims to see similarities
Biochemistry
Same structure, different function
Homologous Structure
same function, different structure
Analogous Structure
Structure inherited from the parents of the offspring, but often unused
Vestigial Structure
Type of structure that is seen when comparing a bird wing and a bee wing
Analogous structure
Type of structure that is seen when comparing a whale fin to a human arm
Homologous Structure
Type of structure defined by the human appendix, a hipbone on a snake, or eyes on a blind mole rat
Vestigial Structure
When examining a fossil record, where is the oldest fossil
the bottom of the sample
List the levels of classification from BROAD to SPECIFIC
Kingdom, Phylum, Class, Order, Family, Genus, Species
In the levels of classification, what is the level that comes right after class
Order
In the levels of classification, which to levels are used in binomial nomenclatures?
Genus and Species
In the levels of classification, what are the two levels that are used in the scientific name?
Genus and species
In a scientific name, which part come first?
Genus
In the scientific name, what must be done to the genus part?
First, capitalized, underline or italized. It can also be abbreviated to one letter.
When writing the species portion of the scientific name, what do you need to remember?
Second word, lower case.
If two organisms have the same order, what other levels are classification are the same?
Everything before it (Class, Phylum, Kingdom
A type of cell that does NOT contain a true nucleus
Prokaryotic Cell
All the kingdoms that have prokaryotic cells
Eubacteria and Archaebacteria
Type of cell that has a true nucleus and organelles
Eukaryotic
All the kingdoms that are eukaryotic
Everything but bacteria ( Fungus, Protist, Plants, Animals)
Name of an organims that has the ability to produce its own food
Autotroph
Type of organism that can not make its own food, it must comsume food for nutrients
