Evolution exam UPDATED Exam
Questions and CORRECT Answers
Which the following statements is most closely related to the modern theory of evolution -
Correct Answer- Organisms best adapted to a change in environment are more likely to
reproduce and Past their genes to offspring
The theory of biological evolution includes the concept that - Correct Answer- Species of
organisms found on earth today have adaptions not always found in early species
Natural selection and it's evolutionary consequences provide a scientific explanation for each
of the following except - Correct Answer- A stable physical environment
The presence of some similar structures and all vertebrates suggest that these vertebrates -
Correct Answer- May have an evolutionary relationships
The similarities of the bones labeled a in the diagram below provide evidence that - Correct
Answer- The organisms may have evolved from a common ancestor
In a group of mushrooms exposed to a poisonous chemicals only a few of the mushroom
survived. The best explanation for the resistance of the surviving mushrooms is that the
resistance - Correct Answer- Resulted from a presence of mutations in the mushrooms
A basketball player develops speed and power as it was all of practice. This athletic ability
will not be passed on to her offspring because - Correct Answer- Hey sequences in the DNA
are not affected by this activity
Which two processes result in variations that commonly influenced the evolution of sexually
reproducing species - Correct Answer- Mutation in genetic recombination
Which characteristic of a population would most likely indicate the lowest potential for
evolutionary change in that population - Correct Answer- Asexual reproduction and few
mutations
, Which of the following statements describes a sexual reproduction - Correct Answer-
Adaptive traits are usually passed from parent to offspring without genetic modification
Which factor could be the cause of the other three in an animal species - Correct Answer- A
lack of genetic variability in the species
Which process is least likely to add to a variety of trades in a population - Correct Answer-
Accurate replication of DNA
Environment that undergoes frequent change species that reproduce sexually may have an in
vantage over species that reproduce a sexually because the sexually reproducing species
produce - Correct Answer- Produce offspring with more variety
Which factor is least likely to contribute to an increase in the rate of evolution - Correct
Answer- A long period of eenvironment stability
Scientist compare boss or means of a species that was 5000 years ago with members of the
same species living today. Scientist conclude that this species had changed very little over the
entire time period.which statement best accounts for this lack of change - Correct Answer-
The environment did not change significantly and those offspring expressing new
characteristics did not survive
Mutations that occur in skin or long cells have little effect on the evolution of a species
because mutations in the cells - Correct Answer- Cannot be passed on to offspring
The teeth of carnivores are pointed in our good for puncturing and ripping flush the teeth of
herbivores are flat and are good for grinding and chewing. Which of the following statements
best explains these observations - Correct Answer- The two types of teeth most likely
involved as a result of natural selection
Diagram below represents for different species of wild birds each species has been with
different structural adaptions. The development of these adaptions can best be explained by
the concept of - Correct Answer- Natural selection
Thousands of years ago draft with store next were common with in giraffe populations.nearly
all giraffes populations today have longnecks. This difference could be due to - Correct
