What is the overarching idea of evolution?
All life descended from a common ancestor
Humans came from apes
Animals adapt based on needs
Only the strongest and most intelligent organisms survive
Which of the following are lines of evidence for the theory of evolution? (There LOTS of answers, choose ALL that apply!)
comparative anatomy
study of DNA
fossil evidence
embryology
molecular biology
A vestigal structure is.....
A structure that is a remnant from our ancestors that provides no function.
A structure that is similar in different organism, but may have a different function
A structure that is very different in different organisms, but has the same function
A structure that is essential for evolution to occur
Which three of the following are examples of vestigal structures?
A homologous structure is.....
A structure that is a remnant from our ancestors that provides no function.
A structure that is similar in different organism, but may have a different function
A structure that is very different in different organisms, but has the same function
A structure that is essential for evolution to occur
Which of the following two (2) diagrams show only homologous structures?
An analogous structure is.....
A structure that is a remnant from our ancestors that provides no function.
A structure that is similar in different organism, but may have a different function
A structure that is very different in different organisms, but has the same function
A structure that is essential for evolution to occur
Which three (3) of the following diagrams show at least one analogous structure?
Darwin believed in the idea of Common Descent, but couldn't quite explain how random changes created such complex, and adapted organisms until.....
he saw our common ancestor on the Galapagos Islands.
he saw that there were so many different types of finch.
he realized that animals adapted to their environments as needed.
he formulated the idea of natural selection.
What did Darwin mean?
That large, intelligent organisms are less likely to survive long enough to reproduce
That organisms change according to the needs of the environment
That organisms that are adapted to their environment have a better change of surviving long enough to reproduce
That evolution is a secret
What is descent with modification?
When the offspring of an organism are exactly like their parents
When the parents of an organism purposely modify their offspring when the environment changes
When the offspring of an organism show genetic variation in comparison to their parents
When parents modify themselves so that their descendents are better adapted to survive
Which two (2) answers are true?
Natural selection is when organisms that are best suited for their environment have a better survival chance than those organisms that are less suited to their environment
Natural selection means the organisms with the fewest changes, which are more natural, have the best chances for survival
Artificial selection happens naturally in the wild
Artificial selection is when humans intervene with nature and only breed organisms with the most favorable traits.
Dark moths are ....
white moths that changed because they needed to be darker to survive
moths that have a different allele for color, which makes them better suited for survival in certain environments
moths that are able to change their color depending on their environment
white moths that have mutated due to the pollution in the air
Evolution is a theory because.....
not everyone believes it
there isn't enough evidence for it to be a reliable explanation
although it is supported by a vast amount of evidence, there is still a lot of evidence still to be found.
dinosaur fossils cast doubt on whether there was a common ancestor to all living things
The three species pictured share a common ancestor and have adapted so that each lives in a different environment. This is an example of...
divergent evolution & homologous structures
divergent evolution & analogous structures
convergent evolution & homologous structures
convergent evolution & homologous structures
The three species pictured do not share a common ancestor, yet have evolved to have a similar anatomy and life style. This is an example of ?
Homologous Structures
Divergent Evolution
Vestigial Organs
Convergent Evolution
