Isolation
The three types of reproductive isolation are:
Temporal, Geographic, Behavioral
When different species become more alike because of similar environments
Convergent evolution
Structures that are similar but have different functions
homologous structures
T or F: The size of a bird determines the size of its beak
False
What kind of rock are fossils found in?
Sedimentary
When two populations of a species can no longer reproduce because they are physically separated
Geographic isolation
When two species that rely on each other evolve together in response to environmental changes
coevolution
Structures that are different but have similar functions
analogous structures
What did Darwin discover about organisms on the Galapagos Islands compared to mainland South America?
They were similar but had some differences
How many years is one half-life of Carbon14?
5700 years
When organisms begin to have different reproductive behaviors
Behavioral isolation
When humans select traits of plants or animals when reproduced
selective breeding
What is embryologic evidence?
Similarities between early embryos of different organisms
Darwin discovered that the Galapagos finches beaks were...
different shapes based on the food that was available in their environment
What are the 3 types of camoufllage?
Concealing Coloration, Disruptive Coloration, Mimicry
When populations begin reproducing at different times
temporal isolation
A type of selective breeding that enhances the traits desired by humans
artificial selection
______________ of different species have similar structures in early stages of development
embryos
The number of finches that Darwin realized were similar but slightly different from the mainland finch
14
When related organisms become more different from each other through generations
divergent evolution
The formation of a new species
speciation
When several new species evolve from one common species
adaptive radiation
Structures that currently have no function but once were functional in ancestors
vestigial structures
Give a reason why the Galapagos Island finches had different types of beaks
1. different types of food available
2. different environments to live in
Dairy farmers select cows that give higher amounts of milk produced in order to increase productivity on their farm. This is an example of ______________.
Selective breeding/artificial selection
