classification / kingdoms Flashcards
(38 cards)
which two taxa do you combine to make the scientic name of an orginism
genus
+species
two name system called
bionomal nomenclature
which taxon ios the broadest
domain
which taxon is most specific
species
how many domains exist
3
a diagram that represents evolutionary relationships( how species chnage from a common ancestor
cladogram
traits that positively affect survival are reproduced at a higher rate than and are more common in a population
adaptation
ratio or percent of an allel to the total genes in the same population
gene frequency
the pattern of distribution of speciesin the world is evidence for evolution
biogeography
study of an orginisms development
ontogeny
can improve or decrease variation for example food/water/predators
enviormental pressures
study of an orginisms early stages of development
embryology
the process by which populations change over time
evolution
a system that gives two names a genus and species to each organism
bionomal nomenclature
preserved remains or trace evidence of an orginism that lived long ago
fossils
study of fossil records showing how organisms are related to each other
palentology
similar structures in anatomy that show a common ancestor
homolouigous structures
sometimes a certain advantgeous traits will allow an individual to survive and reproduce more offspring than others in the population
natural selection
characteristics shared by different species that have very similar structures
comparative anatomy
out dated theory that living things can come from non living things
spontaneous generation
a process by which organisms with favorable traits survive to pass on their genes at a greater rate than organisms with unfavorable traits
heritability
group of organisms of same species living in the same place at the time
population
combination of all genes (alleles) present in a reproducing population or species
gene pool
individuals in a population are different from each other due to differences in alleles
genetic variation
