26) It resulted in more structured human behavior and in many cases more productive.
27) Because they formed at the same time as the Earth but the moon and meteorites were not subjected to the same geologic processes (especially weathering and plate tectonic activity).
28) Stratigraphy
29) Nonconformity
30) Electron capture
31) 6.25%
32) 39 million years
33) Horizontality
34-35) Groups of index or guide fossils that better constrain or limit the age of the rock unit the contains them.
36) Seismic stratigraphy
37-38) a) Selective Preservation
b) Sampling Problems or Decrease in the rock record with increase in rock age
39-40) a) Abundance of individuals
b) Easily recognized
c) Limited age range
d) Geographically widespread
41) Paleobiogeography
42-43) Structures or body parts that evolved from the same ancestral structure or body part but now are much different in different organisms because they are used for different purposes. (Ex. 5-digit bones in bats, birds, humans and whales)
44) Swamp or deep ocean
45) It is where different species start to resemble one another as they adapt to the same environment. (Ex. Birds and Insects)
46) Industrial Melanism
47-48) mutations and genetic recombination
49-50) a) Epidemics
b) Over predation
c) Change in food chain
d) Climatic changes
