Exam 1 Biol 112 TAMU JANES And Exam
2 Questions All Answered Correctly.
Evolution - Answer The change in organisms throughout earths history, DESCENT W
MODIFICATION
Aristotle - Answer Fixed ideal species (scala naturae)
Judeo-Christian bible - Answer Creation and young earth: added God, angels, heaven and
more to ladder of nature
Linnaeus - Answer Looked more at phenotypes; binomial naming
Binomial naming - Answer Capitalize genus and then underline and italicize name
Georges Cuvier - Answer Fossils are a record of change over time caused by catastrophic
changes (rock strata)
James Hutton - Answer Slow continuous processes, geological features
Charles Lyell - Answer Uniformitarianism - mechanisms of change are constant over time
Erasmus Darwin - Answer Natural Philosopher who proposed ideas of evolution; wrote science
as poetry; got Darwin interested in science
Lamarck - Answer Linked evolution to adaptation and first to propose mechanism for
evolution
Mechanism for evolution - Answer - use it or lose it
- inheritance of acquired characteristics
Lamarckism - Answer a theory of evolution based on the principle that physical changes in
organisms during their lifetime could be transmitted to their offspring
Who did Darwin publish with? - Answer Alfred Wallace
, Darwin's theory - Answer 1. Descent with modification
2. Natural selection
Descent with modification - Answer Traits passed down that sometimes undergo changes over
time
Natural selection - Answer Survival of the reproductive fittest; mechanism for evolution
NOT Explained in Darwin's Theory: - Answer 1. Origin of life
2. How variation arises
3. How inheritance works
4. Why variation still exists
5. Sudden changes in fossil record
6. Source of totally new characteristics
Evidence in support of Darwin's theory: - Answer 1. Direct observation
2. Fossil record
3. Homologous
4. Convergence
5. Biogeography
Direct observation - Answer Seeing a species change over time
Homologous - Answer Forms related by common ancestry
Vestigial structures - Answer Remnants of ancestral structures with no present adaptive
function (used to have a use but no longer is needed)
Cellular and molecular homologies - Answer Similarity of cell structures,proteins, and DNA
Viral footprints - Answer DNA left behind by viruses can show common ancestry
Convergence - Answer Unrelated species have similar adaptations under similar
environmental conditions (analogous) (coming together)
Biogeography - Answer Distribution of species; corresponds to geographic history
