Evolution
What is something that is supported by evidence that explains how populations change over time?
Theory of Evolution
The survival and reproduction of organisms that are most fit for their environment
Natural Selection
When an organism matches its environment to hide
Camouflage
How are the arms of humans and bats homologous structures?
They have the same bones/arrangement
When a species becomes a new species through adaptations
Evolution
Evolution mainly looks at _________ over time
change
Breeding certain organisms of the same species in order to get desired traits
Selective breeding
Artificial selection
Mutations that cause organisms to evolve
Adaptations
Human arm and leg, dog leg and paw, bird wing, and whale flipper are examples of this
Homologous Structures
What fossil structure is the real fossil of a real plant or animal part
True Form Fossils
Who is the Father of Natural Selection?
Charles Darwin
The name of the islands where Darwin studied his finches
Galapagos Islands
A ____________ variation causes adaptations
Genetic
Imprints of species left behind
Fossils
A Chart that scientists use to figure out the scientific name of organisms or to help identify footprints
Dichotomous Key
Evolution can only occur when this randomly happens
Mutations
This difference was observed by Darwin in finches on the Galapagos Islands
Beaks
This may occur when a species does not adapt
Extinction
body parts of organisms that
Have DIFFERENT STRUCTURES but a SIMILAR FUNCTION
Analogous structures
Today's whale evolved from what kind of animal?
Land Mammal
Where do related organisms get their shared traits?
Common Ancestor
Another term for Natural Selection
Survival of the Fittest
What other animal did Charles Darwin observe when he was on the Galapagos Islands? Please also explain the different characteristics Darwin observed and why
Tortoises and he observed his their neck sizes because of the food sources that were found on each island.
Body parts that have lost their original function through evolution. Give 2 examples
Vestigial structures
What are the 4 types of fossil structures
Trace, Mold, Cast, True Form
