What are the 8 categories of taxonomic hierarchy (in order from species upward to
broader classifications)?
Give this one a try later!
Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain
What is Taxonomy?
Give this one a try later!
Science of describing, naming, and classifying living and extinct organisms
and viruses
,What is systematics?
Give this one a try later!
Study of biological diversity and the evolutionary relationships among
organisms, both extinct and modern
What is the biological species concept?
Give this one a try later!
-Species is a group of individuals whose members have the potential to
interbreed with one another in nature to produce viable, fertile offspring
-But cannot successfully interbreed with members of other species
What 2 observations the theory of natural selection based off of? What conclusion
(inference) can be made from these two observations?
Give this one a try later!
1. All species tend to produce excessive numbers of offspring.
2. Organisms vary, and much of this variation is heritable
Conclusion: Unequal reproductive success (natural selection)
Mechanical Isolation

, Genital doesn't fit/match
Temporal Isolation
Give this one a try later!
Species mate at different times
What is a population? A species?
Give this one a try later!
Population
- Members of the same species that are likely to encounter each other and
thus have the opportunity to interbreed
Species
-Group of related organisms that share a
distinctive form
-Among species that reproduce sexually, members of the same species are
capable of interbreeding to produce viable and fertile offspring
Hybrid inviability

fertilized egg cannot progress past an early embryo - salamander
