1 monkeys are divided into two major groups:
New and Old World species
1 The X and Y chromosomes are called:
sex chromosomes
1 Regarding the example of the peppered moth,
a. the two color patterns resulted from genetic variation in the species.
c. natural selection acted upon pre-existing variation in the population.

carries a gene that causes a fetus to develop as male.
1 Which are not hominoids?
humans, chimps, gorillas, and orangutans are

1 how many chromosomes occur in a normal human somatic cell?

1 who uses anthropological techniques to assist in crime investigations and to identify skeletal remains in:
forensic anthropologists
1 genetic drift
is a random change in allele frequencies, has its greatest effect in small populations, and includes the phenomenon of founder effect.
1 a hypothesis
is a provisional statement regarding certain scientific facts or observations.
1 primates possess __________, whereas other mammals do not.
highly prehensile hands and the presence of nails rather than claws on most or all digits.
1 after miosis, daughter cells contain the same amount of DNA as the original cell, this is due toL
DNA replication.
1 A prehensile tail
is seen in some New World monkeys, but not in any Old World monkeys.
1 Paleoanthropology
is the study of human evolution as evidenced by the fossil record.
1 birds and mammals
are modern endothermic animals
1 Cells
are the basic units of life
1 Type AB blood is an example of
1 Homozygous
when two copies of the same allele are present in the genotype
1 homologies
structural similarities shared by a species that are acquired by descent from a common ancestor.
1 Social relationships
are crucial to nonhuman primates.
1 Reproductive Success
"fitness" in an evolutionary sense, refers to an individuals..
1 Lemurs
1 Polygenic traits
-are governed by more than one genetic locus.
-their expression is often influenced by genetic/environmental interactions
-the alleles have an addictive effect on the phenotype.
1 Ribosomes
are important to protein synthesis
1 Process of Meiosis
-produces gametes
-are two cell divisions
-produces daughter cells with half the original amount of DNA found in the original cell.
-homologous chromosomes exchange genetic information
THEY DO NOT: produce daughter cells with the same amount of DNA found in the original cell.
1 Mendel's experiment
the uppercase letter was initially meant for homozygous for the allele for tallness.
1 Meiosis
reduction of chromosome number occurs during this.
1 Purely on the basis of genetic similarities, it would be consistent to classify humans and the great apes within the same:
1 Mendel
Discovered independent "units of heredity" (gene) during plant breeding experiments.
1 Lamarck
Early proponent of evolution species. Hypothesize the inheritance of acquired characteristics.
1 Lyell
geological uniformitarianism and the concept of "deep time"
calculated the age of the earth is 6000 years based on the Bible.
1 Malthus
Proposed that species reproduction will exceed the food supply and that intra-species competition for resources would result.
independently stated the concept of evolution driven by the process of "Natural Selection"
2 Current evidence indicates that hominins were bipedal by about
5-7 mya
2 adaptive advantages of bipedalism include
- freeing the hands for making and using tools
- earlier predator detection
-more efficient cooling of the body when one is exposed to the direct sun.
2 anatomical changes in hominins that are indicative of habitual bipedal locomotion include:
shortening and broadening of the pelvis.
2 Relative dating techniques
include biostratigraphy
2 "Robust" paranthropines (P. bosie/P.robustus) probably had a diet primarily composed of
abrasive and heavy foods such as grasses, seeds and nuts.
2 Shortly after Homo erectus fossils are found in East Africe, similar hominins also appear in
2 Homo Habilis
is the hominin species most likely associated with the Oldowan stone tool tradition
all hominins found outside of Africa are members of this genus
2 Homo sapiens would have to exist at least another _______ years to match the time-span of Homo Erectus
1 million
2 The average Neanderthal was
more robust than modern humans
---and the earliest definitive archeological evidence of burials is attributed to Neanderthals.
2 ____make the best samples for the K/Ar dating method
Volcanic rock
2 The oldest fossils of Homo Sapiens are found in
2 Current evidence indicates that ____was the first hominid to migrate out of Africa
Homo Erectus
2 Biostratigraphy
relative dating method is used to CROSS-CORRELATE dates from south african plio-pleistocene hominin sites.
2 The "Complete Replacement Theory" states that
none of the above
2 Certain organic materials less than 75,000 years old:
would be the best suited to the carbon-14 dating technique. (earliest)
2 By using the designation of Homo Habilis Louis Leakey was implying:
-that a larger brain was related to the ability to make the stone tools found with he fossils.
-the Homo lineage was distinct from the australopithecines.
-the homo habilis was more closely related to modern humans than were the austrolopithecines.
2 _____was contemporaneous with Paranthropus but had a significantly larger brain
Homo Habilis
2 Miocene hominoid fossils have been found in:
Africa, Europe, Asia
2 Homo erectus fossils first appear in east africa and are dated to about ____ mya
2 In Africa, Neanderthals have been found at:
Laetoli, Broken Hill, Olduvia Gorge,
2 Bifacially flaked hand axes characterize the ____stone tool industry.
2 Homo erectus DIFFERS most distinctly from modern humans in:
cranial size & shape
2 the dating method that uses the principle that undisturbed underlying geological deposits are older than overlying geologic deposits is called:
stratigraphic dating
2 If an isotope had a half-life of 4 billion years, than in 4 billion years
1/2 of the original amount will still be present.
2 the earliest stone tools are about
2.5 million years old.
2 The hominin fossils from Laetoli and Hadar (Lucy) are classified by most researchers as
Austrolopithecus Afarensis
2 The earliest member of our own genus can be referred to as..
Homo Habilis
2 Based on the current fossil evidence, the initial hominin divergence from the African hominoids most likely occurred..
during the late Miocene
From 6-7 mya ---> 35,000ya
1. Sanelanthropus tchadensis (Chad)
2. Australopithecus Afarensis (Ethiopia)
3. Australopithecus Africanus (South Africa)
