This type of speciation results if members
of the same species are separated and
isolated from one another, while this type
of speciation occurs if the population
comes back together but can’t reproduce
with each other
Allopatric, sympatric
Back
These are types of barriers that
prevent new species from forming
because of potential complications
prior to the conception of an embryo
Pre-zygotic barriers
Back
This is the area where new species
are able to form
Hybrid zone
Back
This is the process where inherited
traits are passed down and result in a
lot of phenotypic variation and
multiple new species, such as in
finches or cichlids
Adaptive radiation
Back
This type of evolution results in similar
traits that derived independently in
different populations that did not
interbreed
Convergent evolution
Back
These were the first living organisms on
planet Earth
prokaryotes
Back
This experiment showed how living things
could have been formed from nonliving
chemicals during the Early Earth
conditions
Miller-Urey
Back
This chemical came around after
prokaryotes and allowed for many animals
to survive
oxygen
Back
These were believed to be responsible for
the assembly of RNA monomers
ribozymes
Back
These are known for being able to carry
out metabolism and could have served as
the first cell membranes
liposomes
Back
This is the naming process that utilizes the
genus and species in italics
Binomial nomenclature
Back
This is a method of comparing characteristics
within characteristics
cladistics
Back
The presence of jaws was a new development in fish,
but was around for a long time before monkeys evolved
and had jaws. To fish, jaws would be this type of trait,
while for monkeys, jaws would be this type of trait
Derived trait, primitive trait
Back
A group that includes a common ancestor and all of its
descendants would be known as this
monophyletic
Back
The simplest explanation is the best describes this
philosophy that is applied to the construction of
phylogenetic trees
parsimony
Back
prokaryote fossils
stromatolites
Back
new species from two species
Hybrid species
Back
more chromosomes in a species that’s
derived from one organism
autopolyploidy
Back
80% of plant species formed from this type
of speciation
Sympatric
Back
Age of the Earth
4.6 billion years
Back
This is the scientist who is best known for
the taxonomy of organisms
Linneaus
Back
Two species that can’t mate because one
species doesn’t know how to dance
properly during courtship would be
separated because of this barrier
Behavioral isolation
Back
This is the theory that eukaryotes gained
organelles from prokaryotes
endosymbiosis
Back
This is the name of a table that indicates
whether or not organisms have certain
traits
Character table
Back
This is the scientist who proposed the idea
that populations have limits on their growth
Malthus

genes formed through speciation
Orthologous genes
Back
another name for a monophyletic group
Clade
Back
This is the name for the speciation event
in which many different animal species
evolved
Cambrian explosion
Back
This is the extinction event that allowed for
the radiation of mammals
Cretaceous
Back
Prokaryotes are believed to have evolved
around this long ago
3.5 billion years
Back
This is the first organelle that was taken in
by the eukaryote during endosymbiosis
mitochondria
Back
These genes are responsible for
development and are found in many
different organisms
Hox genes
