- his last meal had barely

T/F Change is Linear
False, as our supposed innovation are, in reality, problems
- evolution and culture do not always improve with time
Relative Dating
Making comparisons in age; saying something is older than this and younger than this in a temporal sequence
Problems with relative dating
no information on how long something ago something began, lasted, or ended
Absolute Dating
Required analysis [often in lab] of an artifact or material to assign an age in years
Margin of Error
A range you propose in absolute dating, usually (+) or (-) quantitively
Stratigraphic Superimposition
- Relative Dating Method
- Going off the Law of Superimposition to compare the ages of different artifacts and strata
Why Archeology should be precise, not chaotic
Digging up things chaotically may disorganize strata and cause the Law of Superimposition to not apply
Seriation
- Relative Dating Method
- Making comparison in the style of different artifacts to determine their age relative to others
Battle Ship Curve Formation
- Something is Made (low frequency)
- Something becomes trendy (high frequency)
- Something new takes the place, loss of trend (low frequency)
- Abnormal: Rebirth/Resurgence of the lost trend! (Ex: carigans..?)
Dendrochronology
- Absolute Dating Technique
- Using know wood rings that form on logs to determine the conditions and age of something: use of the Regional Master Chronology
Nature's Fingerprint
Wood Rings; they are all unique and known for given temperatures, times, humidity, etc.
Radioactive Isotopes
- Absolute Dating Technique
- Use of the knowledge of half-lives, in collaboration with physicists, to determine the age based on given []
Material to which Radiocarbon Dating applies
ONY ORGANIC MATERIAL, no rocks >v<
How C14 Forms
Cosmic Rays hitting N14
How C4 ends up in humans
Plants take in the C14 from the atmosphere
Humans eat Plants
Trend of C14 Concentration until we Die
- Accumulates, but typically steady, until we die and C14 starts to reconvert to N14
Half-life of C14
5730 Years
Units of measure the [] of C14
Beta-Radiation
In what organic material we find C14
- Faunal Remains (including humans)
- Egg Shells
- Mollusk Shells
