Remains of life from another time
embryo
homologous structures
vestigial structure
fossil
The theory of __ results in organisms with traits better suited to their environment.
acquiredism
natural selection
Lamarckism
developism
Variations are important in populations because they can lead to
more fossils
less evolution
improved environments
new species
The movements of individuals into or out of a population, sexual reproduction, and mutations provide a source of __ to a population.
variation
mutation
metamorphosis
gradualism
Most fossils are found in
amber
bones
ice
sedimentary rock
Organisms produce more offspring than can survive.
true
false
Variations occur among individuals in a species.
true
false
Individuals with helpful variations survive and reproduce better than those without these variations.
true
false
Over time, the offspring of individuals with helpful variations make up more of a species and eventually become a population.
true
false,variations make up more of a population and eventually become a species
Variations result from adaptations in an organisms genes.
true
false, mutations
false, recessive traits
false, dominant traits
Darwin's theory of natural selection emphasizes the differences among individuals in a species.
true
false, similarities
false, more common traits
false, populations
Organisms are made up of all the individual species living in an area.
true
false, kingdoms
false, species
false, populations
Darwin observed that the length of the neck and shell shape of different species of tortoises weren't related to their eating habits.
true
false
Which are example(s) of fossils.
amber
cast
vestigial structures
homologous structures
petrified
The sudden disappearance of a type of fossil in the fossil record is evidence of
camouflage
extinction
pollination
mimicry
True or False: Patterns in the fossil record show that species change over time.
true
false
What determines how closely related 2 species are?
how recently they share a common ancestor
how much they compete for food
how closely they live to each other
how much they compete for mates
What can be inferred about a time period if fossils show many extinctions?
there was no competition between species
there was a lot of species adaptation
there were no species that were similar during this time period
there was lots of environmental change
Through __ a helpful __ can lead to a(n) __.
natural selection, adaptation, variation
natural selection, variation, adaptation
natural selection, variation, mutation
artificial selection, adaptation, variation

(a)
Characteristic of a species that enables the species to survive in its environment.
(a)
Adaptation that enables species to blend in with their environments.
(a)
Resemblance of one species to another species.
(a)
Process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations.
(a)
The breeding of organisms for desired characteristics.
(a)
Slight difference in the appearance of individual members of a species.
(a)
