BSC 111 Prin Of Bio Sci II Chapter 15
UPDATED ACTUAL Exam Questions and
CORRECT Answers
genetic change of a species over time - CORRECT ANSWER - Evolution
Species that are still in existence - CORRECT ANSWER - Extant
anatomical structures that apparently functioned in ancestor but have since lost most or all of
their function in descendant - CORRECT ANSWER - Vestigial structures
Study of fossils - CORRECT ANSWER - paleontology
layers of sedimentary rock - CORRECT ANSWER - Strata
belief, proposed by Georges Cuvier that local catastrophes/mass extractions/worldwide
catastrophes occurred and were followed by repopulation
of surviving species or species from surrounding areas, giving the appearance of changes over
time - CORRECT ANSWER - Catastrophism
idea, created by Jean-Baptiste Lamarck, that environment can produce physical changes in
organism that are heritable - CORRECT ANSWER - Inheritance of acquired
characteristics
Theory composed by Charles Lyell that natural processes witnessed today are same processes
that occurred in past - CORRECT ANSWER - Uniformitarianism
Study of geographic distribution of organisms throughout the world - CORRECT
ANSWER - Biogeography
, Process based on observations that:
Organisms exhibit variation that can be passed from one generation to next - they have heritable
variation
Organisms compete for available resources
Individuals within population differ in terms of their reproductive success
Organisms became adapted to conditions as environment changes - CORRECT
ANSWER - Natural selection
reproductive success of individual relative to other members of population - CORRECT
ANSWER - Fitness
any evolved trait that helps an organism be more suited to its environment - CORRECT
ANSWER - Adaptation
remains & traces of past life or any other direct evidence of past life. - CORRECT
ANSWER - Fossils
Bear resemblance to two groups that in present are classified separately; often represent
intermediate evolutionary forms of life in transition form one type to another or common
ancestor of these types - CORRECT ANSWER - Transitional fossils
Structures that are anatomically similar because they are from common ancestor - CORRECT
ANSWER - Homologous
(Blank) structures serve same function but originated independently in different groups of
organisms that don't share common ancestor - CORRECT ANSWER - Analogous
Genes that orchestrate the development of the body plan in all animals, from invertebrates to
humans - CORRECT ANSWER - Homeobox (Hox)
