Environment Phenotype Phenotype what you can actually observe about the person T tasting dominant TI39 and Tt T nontasting recessive tt Homozygous same alleles at a given locus can either be homozygous dominant or recessive Heterozygous different alleles at a given locus sometimes referred to as carriers of the recessive alleles they have the little t but they still taste bitter Punnett Square Mendel Segregation Independent assortment what goes on at one locus is completely unrelated to what is going on at another locus different loci operate independently from each other Recombination crossing over happens in meiosis genetic variability Blood types March 5 2010 Allele frequency do the calculations Mechanisms for evolution 1 Natural selection 2 Mutation beneficial mutations provide the raw material for natural selection 3 Gene flow genes moving from one group to another group 4 Drift random Bottleneck effect Founder effect shipwrecked British sailor example

equilibrium Speciation when a species splits into two March 24 2010 Archaeological evidence Relative dating Stratigraphy further down you go further back you go Assemblages groups of artifacts found together or in close proximity more useful to study groups of artifacts found together Seriation simply a way of putting something into a series putting together a chronology not absolute dating because you don t assign a date in the chronology Battleship curves think of example from class with hula hoop roller skates and skateboard graph point gt V gt bowed out gt upside down V gt point

to arrow points Flourine Dating Nitrogen Dating and Uranium Dating when bone goes into the ground it absorbs ground water containing fluorine and uranium the bone also loses nitrogen while it is in the ground happens at different speeds at different places fluoridated water uranium in water temperature also effects the processes involved March 26 2010 Obsidian Hydration dating Dating when arrowhead was made not when rock was made older obsidian is the thicker the hydration rind or how far the water has worked itself in will be Temperature hotter faster Speed at which water absorbs into obsidian gt and form the rind gt is linear ex if it takes 1000 years to form a 1 micron thick rind then it will take 2000 years to form a 2 micron thick rind Used on flake obsidian event being dated is the flaking of the obsidian not the creation of the obsidian when somebody made that obsidian into a tool good for 0less than 10000 years not great for something much older than that bc the hydration rind will weather away eventually Connection between event dated and event of interest example about arrowhead next to hearth of fireplace with carbon in it Accuracy vs Precision Dead

around HAVE TO READ Varved sediments Annual pulses of water in lakes mainly glacial lakes can actually find out how old each layer is by what artifacts it lays chronometric dating method Faurnal Remains Animal remains mainly bones Macrobotanical Remains Pine cones charcoal Microbotcanical Remains Pollen tell you about foliage of environment Arboreal Nonarboreal Pollen that can tell you the temperature of the water at the time because it is taking oxygen out of the water and using it helps you look at environmental change very systematically Power point slides avg annual temp dropped 3

llDietary hypothesis so different that they belong in different genus Australopitherus Africanus typically came from Early caves Paranthropus robustus typically came from Late caves Sexual dimorphism should be considered when applied to Africanus llsingle species hypothesis came to light just said what if one is just a male and one is a female of the same species instead of 2 different species Not the case Chewing muscles run out of skull to grow up with a smaller brain and they grow into each other creating a saginal crest Size of canines male larger the female did not support single species concept Dating does not help either Males in 1 time period and females in another doesn t make sense Could determine male and female that fit the sexual dimorphism pattern within the two categories 2

ice age gets a little warmer around 40000 ya around the transition from Middle to Upper Paleolithic Mesolithic Post iceage conditions new categories of resources sea levels rise and large herds of prey migrate Big jump in obvious use of plant materials gt grinding stones or stones to crack open nuts More use of aquatic resources fish Now hunting smaller more dispersed animals instead of bigger herds Pressure builds on rapidly growing human population manipulation of plant resources out of all this comes Neolithic READ New technology AGRICULTURE pottery etc farming is the big thing here could no longer rely on natural plant growth and gathering to feed the growing population same processes happening all over the world at the same time period
