organisms are becoming larger as the earth ages
organisms are becoming more complex as the earth ages
organisms are becoming more adapted as the earth ages
organisms are becoming less fit as the earth ages

analogous structures
homologous structures
morphological structures
vestigial structures
Which pairs of animals show a correct example of homologous structures?
Wings of butterfly and bat
Fingers of human and arm of starfish
Flipper of whale and forelimb of cat
Tongue of frog and proboscis of the mosquito
The greater the number of common homologous organs, _______________.
the more relationships are shared by two groups of organisms
the more recent the two groups of organisms share a common ancestor
the earlier the two groups of organisms share a common ancestor
the more common ancestors that the two groups have
Vestigial structures such as the tailbone and the appendix in humans suggest common ancestry with organisms _______________.
with the same structures that are functioning
with the same structures that are not functioning
without vestigial structures
that appeared in the same period of time
Which of the following contains the information about the body structures and functions in organisms?
amino acids
proteins
genes
nucleus
How is genetics used as a piece of evidence in evolution?
by comparing the genes of closely related organisms
by comparing the genes of organisms with their ancestor
by analyzing the traits of organisms
by analyzing new forms of organisms
Which of the following is a source of modification of organisms in evolution?
heredity
mutation
fertilization
reproduction
Why do organisms with close biochemical similarities show stronger evolutionary relationships?
They have varied and different ancestry.
They have similar patterns during their early stages of development.
They have a common ancestor and have the same kind of proteins.
They possess the same vestigial structure that made their evolutionary relationship closer.
Humans have approximately 96% of their genes similar to those of chimpanzees. Which of the following is TRUE about humans and chimpanzees?
Humans and chimpanzees share a common ancestor.
Humans and chimpanzees evolved from different ancestors.
Humans evolved from chimpanzees.
Chimpanzees evolved from humans.
Which of the following refers to the transformation of species through time?
evolution
adaptation
mutation
variation
Which of the following statements DOES NOT describe evolution?
Evolution is continuous
The world is stable and unchanging
Evolution refers to change
If there is a mutation, there is an evolution
Which of the following describes the process by which species undergo changes over time, with such changes sometimes resulting in the formation of new species?
descent with modification
inheritance of acquired characteristics
natural selection
speciation
What does "higher biological fitness" imply?
the higher capability of an organism to interbreed and produce fertile offspring
the higher capability of an organism to survive the natural conditions
the higher capability of an organism to grow into larger populations
the higher capability of an organism to become the dominant species in a certain ecosystem
How does the process of descent with modification help certain organisms in increasing their chance of survival?
by enabling organisms to adapt to the changing environment at different stages of Earth history
by enabling organisms to evolve into new species
by enabling organisms to establish distinct characteristics
by enabling organisms to direct evolutionary trends to different directions at different times
Which of the following refers to the process in which individual organisms that possess favorable traits have a greater survival rate and higher reproductive success rate?
adaptation
longevity
natural selection
survival
How does natural selection cause evolution?
More selected offsprings of a population will increase the frequency of the selected gene.
More selected offsprings of a population will increase the frequency of their life cycles.
More selected offsprings of a population will increase the frequency of longevity.
More selected offsprings of a population will increase the frequency of mutations.
Which of the following statements best explains the Theory of Natural Selection?
Organs that are not used may disappear while organs that are constantly used may develop.
In nature, the organisms with desirable characteristics may survive while those with weaker traits may not.
Organisms develop desirable structures to survive in a given environment.
Acquired characteristics of parents can be passed on to offsprings.
Which of the following is the ultimate result of evolution?
adaptation
population stability
natural selection
variation
