BIO 1200 FINAL EXAM PRACTICE QUESTIONS
AND ANSWERS (100% PASS)
theory - ✔️✔️a widely accepted explanation for a natural phenomenon that has been
extensively and rigorously scientifically tested
Hypothesis is when you observe something that can be testable and a theory is when
that hypothesis/study gets widely accepted - ✔️✔️What is the difference between a
hypothesis and a theory?
inheritance of acquired characteristics - ✔️✔️is a hypothesis that physiological changes
acquired over the life of an organism (such as the enlargement of a muscle through
repeated use) may be transmitted to offspring.
fossils - ✔️✔️are remains or traces of organisms from the past, usually found in
sedimentary rock, which appears in layers or strata
Sedimentary rocks are deposited into layers called strata and are the richest source of
fossils - ✔️✔️how are fossils formed
transitional form - ✔️✔️is any fossilized remains of a life form that exhibits traits common
to both an ancestral group and its derived descendant group.---land mammals with
whales and dolphins

vestigial traits - ✔️✔️are remnants of features that served important functions in the
organism's ancestors----the human tailbone: monkey tails and human coccyx---
goosebumps: to make yourself look bigger like a cat but for humans it is useless
homology - ✔️✔️STRUCTURES THAT HAVE A DIFFERENT APPEARANCE AND
FUNCTION BUT ARE DERIVED FROM THE SAME BODY PART IN A COMMON
ANCESTOR ARE
phylogeny - ✔️✔️is the evolutionary history of a species or group of related species
developmental homology - ✔️✔️GILL POUCHES IN CHICK, HUMAN, AND HOUSE-CAT
EMBRYOS ARE AN EXAMPLE OF
genetic homology - ✔️✔️
differential fitness, inheritance, variation - ✔️✔️What factors are necessary for natural
selection to occur?
allele frequencies will change - ✔️✔️if a population gradually includes more individuals
with a trait that has been subject to Natural Selection what would we expect to happen
to allelic frequencies that govern this trait?
o Natural selection
o Genetic drift
o Gene flow

o Mutation - ✔️✔️These are four mechanisms that shift allele/genotype frequencies in
populations:
Edits or selects for traits already present in the population - ✔️✔️Selection does what
when present in a population?
fitness - ✔️✔️is the ability of an individual to produce offspring, relative to that ability in
other individuals in the population
•Phylogenic trees show patterns of descent, NOT phenotypic similarity
•Phylogenetic trees do not generally indicate when a species evolved or how much
change occurred in a lineage - ✔️✔️Why do we construct phylogenetic trees?
cladistics - ✔️✔️uses the presence of shared derived characters to infer phylogeny
shared ancestral character - ✔️✔️is a character that originated is an ancestor of the taxon
shared derived character - ✔️✔️is an evolutionary novelty unique to a particular clade
it allows the construction of phylogenetic trees; synapomorphic characters show close
relationships- they can indicate which groups are derived from which ancestors -
✔️✔️What is a synapomorphy, why are they important?
• Homology is similarity due to shared ancestry
