ANT 201, Fall 2019, Lab13: Pleistocene Evolution
Dr. Benjamin Z. Freed, Eastern Kentucky University
Dept. Anthropology, Sociology, & Social Work
PURPOSE:
to introduce comparative cranial-dental anatomy among Pleistocene hominins.
LAB OUTCOMES:
The successful student will correctly be able to:
1)
Compare major cranial-dental features to understand the classification of fossil
hominins.
2)
Identify & describe the taxonomy of Pleistocene hominins.
3)
Recognize when specific human traits first appear in the fossil record.
4)
Identify difficulties with how we define modern humans.
5)
Recognize and differentiate significant paleontological events in the Pleistocene.
6)
Identify and explain each of the following organisms and their significance in
Pleistocene evolution:
Homo
erectus/ergaster, Homo antecessor, Homo
heidelbergensis, Homo neanderthalensis
, and
Homo sapiens
.
7)
Define and describe what factors led to the speciation, spread, and, in some cases,
extinction of the above fossil hominins.
8)
Recognize and explain the significance of dental, cranial, and postcranial evidence
about each of the above fossil humans.
DUE DATE:
Wednesday-Monday, 11/20-25/19

NOTES:
While you look at 6 different species, you will want to examine the traits you see on
the cladogram matrix,
and you will want to look at the following:
1.
Mandibular horizontal ramus: robusticity, chin, buttressing/extra support surrounding
teeth, shape of the dental arcade (block U, U, parabola), retromolar space
2.
Maxilla: prognathism, mid-face projection, robusticity, flaring to the side
3.
Teeth: size/shape issues with the incisors, canines, premolars, & molars; poscanine
megadontia
4.
Zygomatic: flare, depth/height
5.
Frontal: forehead, supraorbital torus (shape, size, length), postorbital constriction
6.
Parietals: size, curvature, sagittal crest, sagittal keel
7.
Temporal: mastoid process
8.
Occipital: foramen magnum, curvature vs. squared-off/angled bottom, nuchal crest,
protuberance, torus, bun
9.
Skull shape: height of maximum breadth; cranial capacity, elongation, eggplant shape.
NAME: _____________________Lab13: Part 2b:
Becoming Human Part 3: 6 pts
1.
Describe two significant aspects of the human (
Homo heidelbergensis
) and
material remains of Atapuerca.
2.
What do the remains at Scladina suggest about growth and development in
Neanderthals?
3.
Describe the diet of the human population of Pinnacle Point.
When did humans
live there?
What do their diet and their material remains suggest about their
thought processes?

Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows:
79.3 75.1 78.2 74.1 73.9 75.0 77.6 77.3 73.8 74.6 75.5 74.0 74.7

If necessary, round all intermediate calculations to four decimal places (e.g. 12.3456).
(a) Calculate a point estimate of the mean pull-off force of all connectors in the population (Round the answer to four decimal places
(e.g. 90.2353).)
(b) Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the
strongest 50% (Express the answer to two decimal place (e.g. 90.15).)
(c) Calculate the point estimate of the population variance (Round the answer to three decimal places (e.g. 3.567).)
(d) Calculate the point estimate of the population standard deviation (Round the answer to two decimal places (e.g. 1.23).)
(e) Calculate the standard error of the point estimate found in part (a) (Round…
