UCSB EEMB 7 Exam 1 Questions With
Correct Answers 2026
Evolution - CORRECT ANSWER -descent with modification, a pattern and a process
Adaptations - CORRECT ANSWER -inherited characteristics of organisms that enhance their
survival/reproduction in specific environments
Explanations on how they arise based on natural selection
Homology - CORRECT ANSWER -similarity resulting from shared ancestry
Homologous structures - CORRECT ANSWER -characteristics with underlying similarities due to
common ancestry but usually have different functions (ex: forelimbs of all mammals have the
same bone structure)
Vestigial structures - CORRECT ANSWER -remnants of features that served a function in the
organism's ancestors (ex: snakes with leftover pelvic/leg bones)
Convergent evolution - CORRECT ANSWER -the independent evolution of similar features in
different lineages, due to organisms adapting to similar environments in similar ways
Analogous - CORRECT ANSWER -features that share similar function but not common ancestry
The fossil record - CORRECT ANSWER -documents the pattern of evolution, shows that past
organisms are different from present-day organisms and that many have gone extinct
Shows evolutionary changes in groups of organisms and sheds light on the origins of new
groups
, Biogeography - CORRECT ANSWER -the scientific study of the geographic distribution of
organisms
Used to predict where fossils of different groups of organisms might be found
Phylogeny - CORRECT ANSWER -the evolutionary history of a species or a group of species
Systematics - CORRECT ANSWER -a discipline focused on classifying organisms/determining
their evolutionary relationships
Taxonomy - CORRECT ANSWER -the scientific discipline of how organisms are named and
classified
Binomial - CORRECT ANSWER -describes the two-part format of organisms' scientific Latin
names
The first part is the name of the genus the species belongs to
The second part is unique for each species of the genus
Hierarchical classification - CORRECT ANSWER -organisms are grouped into a hierarchy of
increasingly inclusive categories
The Linnaean System - CORRECT ANSWER -genera --> family --> orders --> classes --> phyla -->
kingdoms --> domains
Taxon - CORRECT ANSWER -the named taxonomic unit at any level of the hierarchical
classification
Phylogenetic tree - CORRECT ANSWER -a branching diagram that represents a hypothesis about
the evolutionary relationships between a group of organisms
