PALEO 200 Final CORRECT QUESTIONS &
ANSWERS(RATED A)
Carl Linnaeus - ANSWER Founding father of taxonomy
- Introduced a new system for scientifically naming organisms
- 18th century dude
Taxonomy - ANSWER The science of naming and organizing organisms
into related groups
- prior to Linnaeus there was not system which led to considerable
confusion regarding classifying organisms
- system is still used today
- organism is given a binomial name
Binomial Name - ANSWER Consists of 2 parts:
1.*Genus name*
, 2. *specific epithet*
- genus name is capitalized, specific epithet is not
- the binomial name is always italicized (or underlined if writing by
hand)
Ex: /Homo sapiens/
Can a specific epithet be shared by species who are not closely related?
- ANSWER Yes! As long as the genus is different
- the specific combination of genus name and specific epithet are not
permitted to be shared by any two species
The Rule of Priority - ANSWER States that once a species has officially
been given a binomial name, the named cannot be changed (unless it
turns out that the organism is not really a *new* species)
How must a biologist officially give a new species a binomial name? -
ANSWER They must publish a description of the new species in a widely
distributed and peer-reviewed scientific publication
, - they must also designate a holotype specimen
- the published description must contain a list or combination of
characteristics that makes the new species unique
Peer-reviewed Scientific Publication - ANSWER Is one that is not
published until it has been reviewed by other scientists to verify that
the contents of the publication are legitimate and scientifically
reasonable
Holotype - ANSWER A specimen that is a physical example of the new
species
- it must be kept at a research institution such as a university or
museum such that other scientists may study it
- does not necessarily have to be a complete specimen (dinosaur
holotypes are hardly ever complete)
- in case you were wondering, there is no /Homo sapiens/ holotype. I
googled it
Just because 2 organisms look different are they separate species? -
ANSWER No! Individuals may differ morphologically due to intraspecific
variation
, Interspecific Variation - ANSWER Individuals that differ in morphology
because they belong to different species
Instraspecfic Variation - ANSWER Individuals who belong to the same
species but have different morphologies
Ex: Tyler an Austin look different, but still belong to the same species
Four types of Intraspecific Variation - ANSWER 1. sexual dimorphism
2. ontogenetic variation
3. individual variation
4. taphonomic variation
Sexual Dimorphism - ANSWER When males and females of the same
species look different
Ontogenetic Variation - ANSWER The variation that you can see
between young and old individuals of the same species
