Up until the late eighteenth and early nineteenth centuries, many naturalists believed that all species of living
organism(s) had been created separately and had remained unchanged since the creation. Around that time,
scientific research provided findings that were contradictory to that idea. All of the following are findings that
contradict the idea of a single creation. Choose the exception.
A) The platypus is only found in Australia and the dodo was only found on Madagascar.
B) Some fossils of extinct organisms are quite different from living organisms.
C) As scientists explored more of the earth, they found that different groups of organisms were found in
the different regions.
D) Even though the limbs of various mammals carry out different functions (swimming, gliding, running,
holding, etc.), the bone patterns are very similar.
E) The limbs of some mammals serve the same purpose but their bone patterns are very different
Which of the following is the best description of an adaptation?
A) a trait that will be beneficial in the future
B) an environmental change that selects for certain traits
C) a trait that was beneficial to survival in the past
D) a trait that is of no advantage to survival
E) a trait that is currently beneficial to survival
A population in Hardy-Weinberg equilibrium
A) requires a small population size.
B) consists of allele frequencies that are constantly changing.
C) consists of genotype frequencies that are constantly changing.
D) is under no selective pressures.
E) is very common in nature.
Human chorionic gonadotropin (hCG)
A) is produced by the amnion.
B) is stored in the ovaries.
C) can be used to reveal pregnancy.
D) is needed to form the placenta.
E) acts as a hormone signaling menstruation.
Which of the following statements about natural selection is true?
A) Natural selection causes variations to arise within a population.
B) All individuals within a population have an equal likelihood of survival. Survival is based on chance.
C) Natural selection leads to extinction.
D) Natural selection leads to increased likelihood of survival for certain individuals based on variation. The
variation must come from outside the population.
E) Natural selection results in those individuals within a population who are best-adapted surviving and
producing more offspring
On a molecular level, all organisms
A) show no similarities.
B) use different means of storing genetic information.
C) have the same bases in DNA and RNA, the same amino acids in proteins, and use the same genetic
code.
D) have the same bases in DNA and RNA, but different amino acids in proteins.
E) have the same bases in DNA and RNA, the same amino acids in proteins, but use different genetic
codes.
Which of the following is not true of the punctuated equilibrium theory?
A) It suggests that subgroups diverge and evolve at about equal and constant rates.
B) It proposes that most evolutionary change is concentrated in relatively brief episodes of change.
C) It suggests that most species undergo little phenotypic change during most of their evolutionary
duration.
D) It was inspired in part by patterns observed in the fossil record.
E) It appears to be well supported by the fossil record.
