1.
Which of the following have been used by scientists to determine evolutionary relationships and divergence times between primate species or lineages?
2.
Problems with interpreting information from the fossil record include:
3.
Cultural practices - such as those pertaining to agriculture - can play a significant role in influencing the evolution of infectious disease microbes.
True
False
4.
Populations that evolved to include high numbers of individuals with the "thrifty genotype" include higher frequencies of the following health problems:
5.
Human behavior is one of the critical factors that contribute to the evolution of more virulent (harmful) bacterial and viral strains.
True
False
6.
Large agricultural and urban populations may be more vulnerable to infectious disease due to their:
A. evidence from the fossil record B. behavioral observations of living primates C. molecular phylogenies D. all of the above E. A and C are correctExplanation / Answer
Answers: -
1.option-'E'
2.option-'D'
3.option-'B'-False.
Mostly, infectious disease emergence in humans is caused by pathogens of animal origin, so-called zoonoses.
Likewise, cross-over events may occur between non-human species including between domestic animals and wildlife, and such events also involve transmission from a reservoir population into a novel host population but not by cultural agriculture practises.
4.option-E-
Obesity and diabetes type 2
The thrifty gene hypothesis, or Gianfranco's hypothesis is an attempt by geneticist James V. Neel to explain why certain populations and subpopulations in the modern day are prone to diabetes mellitus type 2 and obesity.
5.option-'A'-true
because of indiscriminate use of antibiotics
6.option-'E'-larger population size and sedentary lifestyle.
