The driving force of evolution, in which species that are best fit for an environment will survive.
What is natural selection
100
Darwin studied these types of animals on the Galapagos Islands
What are finches and tortoises.
100
This provides the raw material for evolution by ensuring that one organism is more different from the other.
What is mutation/variation
100
Name examples of homologous structures
Bat wing, whale flipper. Horse leg, human leg
100
This occurs when species do not mate because they live in different areas.
What is habitat isolation.
200
A method in which you compare similar strata with relatively the same age and similar organisms to determine the age of a fossil
What is relative dating
200
This type of selection occurs when dog breeders choose certain dogs that show desired traits
What is artificial selection
200
This is the reason that competition must occur and that only some organism can reproduce.
What are limited resources.
200
Wings of birds and butterflies are an example of what structure
What is an analogous structure
200
This occurs when species do not mate due to different mating seasons.
What is temporal isolation.
300
A method where you use the half-life of radioactive isotopes, by comparing them to the radioactivity of a modern day organism, to determine the age of a fossil
What is absolute dating
300
Darwin's book was titled this
What is On the Origin of Species
300
Evolution produces populations that are adapted to this.
What is their environment.
300
Darwin discovered that many lines of evidence support the hypothesis of common descent. What piece of evidence wasn't found until after Darwin's time.
Biochemical Evidence
300
This occurs when species do not mate because their genitals or equivalent are incompatible to each other as mates.
What is mechanical isolation
400
This occurs when a natural disaster or human interference takes place; it prevents the majority of the genotype to appear in the next generation
What is the Bottleneck Effect
400
Describe what is meant by an organisms fitness
The reproductive success of an individual, relative to other members of a population. The most fit will get more resources, giving it a higher chance of producing offspring.
400
Some organisms are more fit than others, causing them to have this
What is increased reproductive rate.
400
This type of evidence focuses on distribution of plants and animals throughout the world
What is biogeographical evidence
400
This occurs when species do not mate because the males and females do not recognize each other as mates.
What is behavioral isolation.
500
Similar fossils found in the same strata, but in different locations. Allows strata at one location to be correlated with a strata at a another location.
What is an index fossil
500
This person created a similar hypothesis, persuading Darwin to publish his book
Who is Alfred Russel Wallace
500
In an evolving population, more and more individuals will be this over time.
What is fit/adapted.
500
Pieces of bone, impressions of plants pressed into shale, and insects trapped in tree resin are examples of
fossils
500
This occurs when gametes of different species do not combine into a zygote after mating.
