Biology 105 Exam #4 Practice
Questions and Correct Updated
Answers 2026.
Organic Evolution and Special Creation are considered as this. - Answer Broad Concepts to
Explain Origins
A gradual change in organisms through time, generally with organisms becoming more complex.
- Answer Evolution
Proposed a theory on the mechanism of evolution based on the inheritance of acquired traits
involving the use and disuse of structure. - Answer Lamarack
A geologist who reinforced the ideas of uniformitarianism, the idea that the present is the key
to the past. - Answer Lyell
An economist who indicated that the human population is limited in size by food supply and
other factors such as disease and war. - Answer Malthus
Formulated the theory of Evolution based on Natural Selection. - Answer Wallace
Wrote a very convincing book explaining how biological evolution could occur based on Natural
Selection. - Answer Darwin
What was the significance of the HMS Beagle? - Answer It was Darwin's sailing ship.
What was the title of Darwin's book explaining evolution? - Answer Origin of Species
Where are the Galapagos Islands and why are they important? - Answer They are a small
archipelago of dry volcanic islands isolated 600 miles off the coast of South America. They are
sometimes thought of as laboratories of Evolution; it was here that Darwin got some of his most
important ideas about Evolution.
How did the Galapagos creatures and Darwin's finches influence Darwin's ideas about special
creation? - Answer Most of the animals there have evolved from their ancestors before.
a. Genetic Variation is Characteristic of all Organisms
b. Organisms overproduce young, but population size remains relatively constant.
, c. There is a struggle for existence among all the offspring for available resources.
d. The is survival of the fittest by means of Natural Selection. - Answer The Postulates of the
Darwin Theory.
Ancestral giraffes with short necks; wanted to reach upper branches, so by stretching their
necks and legs, they eventually made their necks and legs longer. - Answer Lamarack's
hypothesis
Variation is characteristic of all species and, in the case of the giraffe, those individuals that
happened to have slightly longer necks were better adapted and thus they survived and
reproduced. - Answer Darwin's hypothesis.
Evidences for Evolution - Answer Paleontology
The traces of preexisting life found preserved in the Earth's crust. - Answer Fossil
1. Fossils of organisms preserved in the Earth's crust are different from present-day organisms.
2. As one looks further down in the fossil record, one sees more and more differences. - Answer
Two Evidences for Evolution from Paleontology
Vertebrates have the same general patterns of blood circulation, bones, muscles, digestive
system, reproductive system, etc. - Answer Comparative Anatomy
The same general pattern of development is repeated in all vertebrates. - Answer
Developmental Biology
The areas of the world which are separated from one another have different species of
organisms instead of common ones on all the continents. - Answer Biogeography
All organisms have the same genetic material, DNA. - Answer Biochemistry and Molecular
Biology
In just a few thousand years, humans have vastly changed various species of plants and animals
by selective breeding. - Answer Artificial Selection
Geological theory stating that the continents were all together at one time. - Answer
Continental Drift
a. Mutation
