made up of individuals, number same species found in its habitat TERM 2
DEFINITION 2 change over time TERM 3
DEFINITION 3 "survival of the fittest" fittest means youcan leave behing offspring, those best suited to current conditions survive and reproduce leaving offspring TERM 4
DEFINITION 4 most credit for evolution, alfred wallace had the same idea, but darwin had more, he had a book full of information TERM 5
DEFINITION 5 shifts in alleles
the percent of time each allele appears TERM 7
DEFINITION 7 fossils, biogeography, comparative anatomy and embryology and molecular biology TERM 8
DEFINITION 8 incomplete record,relative dating are the layers the ones at top are newest and bottom are the oldest, radiometric dating is when youuse radioactive isotopes: carbon 12 the isoptos is carbon 15 which has two extra neutrons and very unstable when you die carbon 14 starts to go away but takes very very long to go away TERM 9
DEFINITION 9 the geographic patterns of species distributions TERM 10
DEFINITION 10 make DNA and protein comparisons, you are able to compare bacteria and humans using this process, if sequence similarity is high then they have alot of similarity and closely related
way to organize organisms with putting them in order so they can be grouped togeter TERM 17
DEFINITION 17 mutation, genetic drift, migration and natural selection TERM 18
DEFINITION 18 altered sequence in DNA, cause by replication errors or exposure to mutgens, if a mutation is in a germ cell then it can be passed on to the offspring TERM 19
DEFINITION 19 random change in allele frequencies, unrelated to alleles' influence on reproduction, types are bottleneck and founder effect TERM 20
DEFINITION 20 when only a few individuals survive a natural disaters or illnes
a new population may be started when a few individuals travel and colonize a new area TERM 22
DEFINITION 22 the movement of some individuals of a species from one population to another, influenced by mobility of organisms, alleles may be "carried into" a population which can alter allele frequencies TERM 23
DEFINITION 23 three conditions: 1variation for the trait within the population 2, variation must be inheritable 3."differential reproductive success" bases on the trait alleles must be able to be pasted on TERM 24
DEFINITION 24 Stabilizing selection, directional selection, disruptive selection TERM 25
DEFINITION 25 for a population to be in equilibrium it must satisfy five main conditions: 1. the poplulation is very large 2. matins is random 3.the population is isolate (no gene flow) 4. no mutations 5. all individuals are equal in reproductive succes (no natural selection)
occurs within same geographic area, usualy with plants, mistakes heppen in the cell division that end with a new organism so that that organism can no longer mate with the other. TERM 32
DEFINITION 32
DEFINITION 33 evolutionary history of a species or group of species, hypotheses developed by using fossils, homologous morphological triats, behaviors and molecular sequences TERM 34
DEFINITION 34 change and adapted to their own envioronments TERM 35
DEFINITION 35 connects classification with evolutionary history,2 part name: genus and species, taxonimic unit: taxon, most specific is the species most broad is the domain of the organism
hypothesis of evolutionary relationships within a group TERM 37
DEFINITION 37 monophyletic: one group or tribe, uses the concept that evolution proceeds when a new heritbale triat develops and is passed on to descendents, new triats that come up are called derived characters TERM 38
DEFINITION 38
