chapter 4 evolution

QuestionAnswer
beleived world was created 6,000 years ago
aristotle stated organism r fixed and do not change
idea of uniformitarianism- earth developed gradually over a long period of time charles lyell
theory of lamarkism- older fossils of primitive animals, younger fossils of more complex animals lamark
father of evolution darwin
darwin wrote? the origin of species
who stated decent with modification present day species come from succesion of ancesters
nature selects natural selection
came up with same idea as darwin wallace
earths age 4.5 billion y.o.
oldest fossils(stomatolites)age 3.5 billion y.o.
the older the fossils, the more simple
the younger fossils, the more complex
similar structures from similar organism and same embryotic origin homologous structure
rudimentary, no functions vistigial organs
study of geographic distribution of living organisms biogeography
unrelated species have similar structures, due to similar environments analogous structures
foraminifera(marine protists) gradual change
1 population is split into 2 or more populations divergent evolution
fan shaped branching pattern of evolution adaptive radiation
2 or more dissimilar species evolve structures that make them appear superficially convergent evolution
rare, sudden changes in genotypes, and a new phenotype may occur for survival mutation
change in an allele frequencies due to immigration or interbreeding gene flow
due to change, occurs in any size population, and a loss of genetic variation genetic drift
small surviving population may not represent the original gene pool bottle neck effect
extra finger,toe founder effect
can alter genotype ratios non random mating
early earth frigid, warming, cooling, tumultous, plate tectonics
atmosphere poisonous and no free oxygen
stanley miller primordial soup
stage where oldest fossils were found precambrian
stage of plate tectonics, pangea paleozoic
dinosaur era, pangea broke apart mesozoic
age of mammals cenozoic
patterns that have existed anaerobic to aerobic prokaryotic to eukaryotic aquatic to terrestrial fish to amphibians to reptiles to birds to mammals
the evolutionary history of a group of species phylogeny
species placed in categories taxonomy
when was morphology used past
now we use morphology, embryology, and molecular taxonomy
categories domain, kingdon, phylum, class, order, family, genus, species
domains bacteria,archea, and eukaria
when 2 different species mate hybrid
ways new species arise allopatric speciation parapatric speciation sympatric speciation
reasons for extinction don't mate right, breeding with other species, environmental changes
smallest living cells bacteria
bacteria multipy by binary fission
pathogenic bacteria cause diseases
virulence bacteria very strong
importance of bacteria nitrogen fixators, decomposers, make foods
e. coli in intestines- help digest foods
coccus round
bacillous rod
sparillum spiral
bacteria stain gentian violet
gram + purple
gram - pink
when conditions r harsh endospores
first eukaryotic cell protista
protistas arose from prokaryotes
amoeba pseudopods
paramecium cilia
giardia flagella
diamaceous earth produce more oxygen than all land plants combined
dinoflagellates red tide
diatoms marine
plasmodium vivax causes malaria passed on by misquitos
common algae green
algae found in deep waters red
algae found on kelp brown
gills 1 tonsils 2 eustation tube 3 thymus gland
