LSU BIOL 1202 Pomarico Exam
Questions and Correct Answers 2025-
2026 Updated.
evolution - Answer descent with modification; change over time
changes in evolution - Answer a change in the frequency of the alleles of a population
-mutation which favors one allele over another
-mutation which creates a new allele that is favored
time in evolution - Answer several generations for the organism
-for bacteria --> a day or two could be plenty
-for humans --> may be 200-300 years
Charles Darwin - Answer first "convincing" case of evolution published in 1985 was written
by whom?
creationism - Answer may be strictly Biblical or may involve continual creation
fossils - Answer evidence of some of the organisms which have existed on earth is preserved
as?
What is seen in the fossil record? - Answer A succession of organisms
-the differences between fossils and living species are great
-new species appeared and others became extinct
Cuvier - Answer Which French anatomist founded the science of paleontology (the study of
fossils) and the theory of catastrophism?
catastrophism - Answer theory which states that the major changes in the Earth's crust are
the result of catastrophic events rather than gradual process of change
geological gradualism - Answer the predecessor of evolution
Hutton - Answer Late 1700s geologist that proposed the large changes seen in the fossil
records were the result of uniformitarianism
, uniformitarianism - Answer principle that profound change is the cumulative product of
slow, continuous processes
Lamarck - Answer Who placed fossils in an evolutionary context and compared modern
species to the fossil record and identified several lines of descent consisting of a succession of
older fossils --> younger fossils --> modern species and was published in 1809?
Also envisioned many "ladders" of evolution which organisms could "climb"
ladder of evolution - Answer least complex organisms at the bottom were spontaneously
generated ; the complexity of organisms increased in a "march toward perfection" and the most
complex organisms were at the top
mechanism of change - Answer 1) use and disuse - use it, or lose it philosophy
2) acquired traits can be passed along to the next generation
WRONG
HMS Beagle - Answer The boat Darwin voyaged on in 1831
Darwin's observations - Answer -observed that South American organisms differed from
European forms
-species of finches in Galapagos Islands were unique but resembled species of South America
The Origin of Species - Answer Darwin's observations in a book published in 1859
Tree metaphor - Answer history of life
-at each branch or fork the species have a common ancestor
-similar species have branched recently
-species with greater differences branched long ago
-most branches are dead ends
Natural selection and adaptation - Answer Observation 1: Populations have potential for
exponential growth
Observation 2: Population size is normally stable
Inference 1: Survival is a struggle, and only a fraction will survive
Observation 3: Traits are variable among individuals of a population
