BIOL 214 EXAM 1 (CWRU) Exam TEST
EXAM QUESTIONS AND ANSWERS
100%- SOLVED (Newest UPDATE 2025
Darwin's contribution to understanding diversity - CORRECT ANSWERS 1. evolution
2. gradualism
3. speciation
4. common ancestry
5. natural selection
Speciation - CORRECT ANSWERS separated geographically
takes its own course of evolution
formation of new species
Natural selection - CORRECT ANSWERS does not apply to acquired characteristics (heritable traits
only)
Scala Naturae (Aristotle) - CORRECT ANSWERS The Great Chain of Being
all living organisms arranged in a linear order from simple to complex
Lamarck - CORRECT ANSWERS 1. species change through time (transmutation)
2. acquired characteristics are passed down in generation
3. organisms change in response to environment
4. specific mechanisms lead to evolutionary change
, Lyell - CORRECT ANSWERS Uniformitarianism - mechanisms of change are constant over time
(slow processes are still at work today)
Hutton - CORRECT ANSWERS Gradualism: geology we see is the result of slow processes acting
over long periods of time
Wallace - CORRECT ANSWERS Father of Biogeography
developed the mechanism of natural selection independent of Darwin
(natural selection is responsible for evolution)
Thomas Malthus - CORRECT ANSWERS humans competing for limiting food resources
Darwin: fight for survival; those don't adapt die
Cuvier - CORRECT ANSWERS catastrophism: believed that the extinction of species was caused by
catastrophic events such as floods
different layers of fossils = remains of organisms that had died in a local catastrophe
How long can a cabbage seed soak in salt water still germinate? - CORRECT ANSWERS a variety of
cross-oceanic dispersal methods were possible
Evolution - CORRECT ANSWERS heritable changes in the phenotype of a population over
generations
Inference 1: individuals within a population compete for limited resources - CORRECT ANSWERS
1) most organisms produce more than 1 or 2 offsprings & are capable of exponential growth under ideal
conditions
2) populations do not increase in size indefinitely
