1 Species that produce relatively large numbers of offspring and invest little parental care are said to be:
1 structural similarities shared by a wide array of distantly related species that are inherited from a common ancestor, such as the number of bones in the forelimb, are termed:
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.
1 who uses anthropological techniques to assist in crime investigations and to identify skeletal remains in:
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 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
structural similarities shared by a species that are acquired by descent from a common ancestor.
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 Process of Meiosis
-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 Purely on the basis of genetic similarities, it would be consistent to classify humans and the great apes within the same:
Early proponent of evolution species. Hypothesize the inheritance of acquired characteristics.
Proposed that species reproduction will exceed the food supply and that intra-species competition for resources would result.
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 "Robust" paranthropines (P. bosie/P.robustus) probably had a diet primarily composed of
abrasive and heavy foods such as grasses, seeds and nuts.
2 Homo sapiens would have to exist at least another _______ years to match the time-span of Homo Erectus
2 The average Neanderthal was
more robust than modern humans
---and the earliest definitive archeological evidence of burials is attributed to Neanderthals.
relative dating method is used to CROSS-CORRELATE dates from south african plio-pleistocene hominin sites.
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.
(ALL THE ABOVE)
2 the dating method that uses the principle that undisturbed underlying geological deposits are older than overlying geologic deposits is called:
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 hominin fossils from Laetoli and Hadar (Lucy) are classified by most researchers as
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)
4. australopithecus Boisei (Tanzania)
5. homo Habilis (Kenya)
6. homo erectus (Java-Indonesia)
7. Homo Sapien (France)
refers to an adaptive change that is reversible when condition return to their former condition
