Biological Anthropology EXAM #1-UGHHH Questions and Answers
What makes physical anthropology scientific? - Answer-It depends upon the use of the
scientific method (testing hypotheses and making theories to explain
natural phenomena).
List a couple of examples of what physical anthropologists do. - Answer-1. Skeletal
biologists study archaeology or forensic contexts.
2. Human biologists study the range of variation in modern human adaptations.
What is science? - Answer-The activity of seeking out reliable explanations for natural
phenomena.
Number the steps of the scientific method in the correct order from 1 to 5, and fill in the
blanks.
______ Ask a question (why, what, how, etc. )
______ Experiment or collect data.
______ State a _______, which is based on a corroboratted ______.
______ Oberserve some phenonomenon.
______ Propose a _______, which must be testable/falsifiable. - Answer-2.
4.
5; theory; hypothesis.
1.
3; hypothesis.
Explain hypothesis and theory and the difference between them. - Answer-A hypothesis
is an educated guess to answer a question, whereas a theory is supported by a body of
evidence - like multiple hypotheses.
What is the definition of evolution? - Answer-A change in allele frequency in a gene pool
over time.
What is allele frequency? - Answer-How often each allele for a given trait occurs in a
gene pool.
What is a population? - Answer-A group of potentially interbreeding organisms.
List the four main evolutionary forces. - Answer-1. Gene flow
2. Genetic drift
3. Mutation
4. Natural selection
, Explain the difference between natural selection and evolution. - Answer-Evolution is a
change in a population's allele frequency over time, and natural selection is one of the
four factors that cause a change to occur.
Explain why variation within each species is important for natural selection. - Answer-
Variation causes some individuals to be better adapted to their environment than others
and can result in higher reproductive success.
What is wrong with the statement, "Evolution is just a theory"? How would you respond
if someone said this to you? - Answer-A scientific theory is a goal in life sciences; it is
based on corroborated hypotheses after experimentation and/or data collection. The
common use of the word theory is equivalent to the scientific hypothesis, which has not
yet been tested through experimentation and/or data collection
Explain how evolution in non-progressive. - Answer-Species do not evolve in a
predetermined way (toward a goal). Traits are selected for by natural
selection depending upon environmental conditions, which change over time.
What is wrong with the statement, "If humans evolved from apes, why are there still
apes"? How would you respond if someone asked you this? - Answer-Humans did not
evolve from modern apes, we share a common ancestor, known as hominins.
Why have humans changed more than chimpanzees and gorillas since diverging from
our shared common ancestor? - Answer-Apes have gone under less selective pressure
from the environment.
What are chromosomes made of? - Answer-DNA
How many chromosomes are in a human somatic cell? - Answer-46
Hoe many chromosomes are in human gametes? - Answer-23
The # of chromosomes in a human gamete is referred to what? - Answer-diploid
number
if a chickens cell has 78 chromosomes, how many chromosomes would the chickens
sperm cell have? - Answer-39
How can we distinguish the 23 types of chromosomes from one another? - Answer-size,
centrom location, bonding pattern
What is a gene? - Answer-A section of DNA that codes for a trait
What makes homologous chromosomes homologous? - Answer-what is on the
chromosome makes it homologous
