|
Captive Study |
Primate behavior study conducted in a zoo, laboratory, or other enclosed setting |
|
|
Semi-free-ranging study |
Primate behavior study conducted in a large area that is enclosed or isolated in some way so the population is captive |
|
|
Field study |
Primate behavior study conducted in the habitat in which the primate naturally occurs |
|
|
Female philopatry |
Primate social system in which females remain and breed in the group of their birth, whereas males emigrate |
|
|
Male philopatry |
Primate social system in which males remain and breed in the in the group of their birth, whereas females emigrate |
|
|
Monogamy |
A mating bond; primates can be socially monogamous but still mate occasionally outside their pair bond |
|
|
Polygyny |
Mating system in which one man is allowed to take more than one wife |
|
|
Taphonomy |
The study of what happen to the remains of an animal from the time of death to the time of discovery |
|
|
Polyandry
|
Mating system in which one female mates with multiple males |
|
|
Fission-Fusion Polygyny (p.215) |
Type of primate polygyny in which animals travel in foraging parties of varying sizes instead of a cohesive group |
|
|
Stratigraphy |
The study of the order of rock layers and the sequence of events they reflect |
|
|
Petrifaction |
The process of being turned to stone |
|
|
Original Horizontality |
Layers of rock (strata) are laid down parallel to the earth's gravitational field and thus horizontal to the earths surface, at least originally |
|
|
Superposition |
With all other factors equal, older layers are laid down first and then covered by younger (overlaying) layers. Leaving older sediments are on the bottom, and the fossils found in them are older that those found above. |
|
|
Cross-cutting relationship |
Which says that a geological feature must exist before another feature can cut across or through it, and that the thing that is cut is older than the thing cutting through it |
|
|
Faunal succession |
Proposed in 1815 by William Smith (nick named "Strata") addresses the change or succession of fauna (animals) through layers. That not only deeper fauna is older, but that there are predictable sequences of fauna through strata, that successive layers contain certain types of faunal communities |
|
|
Chronometric Dating Techniques |
Technique that estimates the age of an object in absolute terms through the use of a natural clock such as radioactive decay or tree ring growth |
|
|
Relative Dating Techniques |
Dating Techniques that establish the age of a fossil only in comparison to other materials found above or below it. -Lithostratigraphy: using rock layer characteristics to correlate across regions |
|
|
Relative Dating Techniques |
-Tephrostratigraphy: Variant of Lithostratigraphy that uses the chemical fingerprint of volcanic ash to correlate across regions-Biostratigraphy: relative dating technique using comparison of fossils from different stratigraphic sequences to estimate which layers are older than others |
|
|
Adapoids |
Family of mostly Eocene primates, probably ancestral to all strepsirhines |
|
|
Omomyoids |
Family of mostly Eocene primates probably ancestral to all haplorhines |
|
|
Proconsul |
Discovered in the 1920's in East Africa, Proconsul is thought to be the last ancestor between apes and hominins |
|
|
Mototpithecus |
20 (MYA) is the earliest fossil ape to show post-cranial adaptations similar to those of livings apes like: short and stiff back, suspensory shoulder anatomy, massive front teeth and premolars for extremely hard food |
|
|
Oligopithecidae |
36 (MYA) very primitive with strepsirhine-like molars. Had fused frontal bone and post orbital closure |
|
|
Parapithecidae |
Includes the genus Apidium. Resembles South American Squirrel Monkey. Had monkey-like teeth with three premolars |
